Timeline of the Ancients: Legacy Period: A.D. 2007 to Present

Timeline of the Ancients

Introduction

This timeline is part of a larger timeline that covers the over 50-million-year history of the Ancients. To view the entire timeline, visit Timeline of the Ancients, which also includes an overview of the Ancients' evolutionary path and author's notes.

**MAJOR HISTORICAL PERIODS OF THE ANCIENTS**
Date Range	Period	Human	Ascended	Galaxy	Notes
Over 50 million years ago	Alteran	Yes	Uncertain	Original home galaxy, often referred to as simply the Ori galaxy because only the Ori remained there.	The Altera and their brethren the Ori were humans on the evolutionary path toward ascension, but it is unknown if there were ascended beings who existed before or during this period, and if they existed, whether or not the humans were aware of them. The Ori greatly outnumbered the Altera and were preparing to wipe them out because of their conflicting philosophical views. By the end of this period, the only Ancients that existed were the Altera, the mountaintop villagers who chose to leave their home aboard a single spaceship rather than engage in a war. The Ori were left behind to continue on their own path.
5 to 10 million years ago to 50 million years ago	Ancient	Yes	Possible	Primarily in the Milky Way, their new home that they named "Avalon". The Altera became known as the Ancients.	This period includes the establishment of the Stargate network in the Milky Way, the exploration of their new home galaxy and others through the launch of their exploration fleet of Stargate-seeding starships and follow-up exploration vessel Destiny (see Stargate Universe), the formation of alliances, the advancement in weapons and other technology, the development of the means to collect and store their accumulated knowledge, and the continued research into the acceleration of evolution through genetic alteration to achieve ascension. Some of the Ancients had evolved to the point that they could ascend on their own. The defining moment that ends this period is the occurrence of the plague that swept throughout the galaxy that forced the Ancients to ascend, to leave the galaxy, or to die out. Because of the plague and the heightened research into ascension, the Ancients never boarded Destiny, but instead left the exploration fleet to continue on its automated course.
10,000 years ago to 5 to 10 million years ago	Lantian	Yes	Yes	Pegasus. The Ancients were called the Ancestors by the humans of the Pegasus galaxy.	This period opens with the plague sweeping throughout the Milky Way that forced the Ancients to leave the galaxy in one form or another—whether it be by ascending, by leaving the galaxy as humans (in spaceships, for example), or by dying out. The Ancients that ascended joined together in a collective called The Others. The Ori, although not hit by a plague, also ascended and established themselves as the gods of the religion "Origin". This period also includes the creation of the second generation (evolution) of humanity in the three galaxies: the original Altera/Ori home galaxy, the Milky Way, and Pegasus. As they did in the Milky Way, the Ancients in Pegasus built a Stargate network and settled on several planets. By the end of this period, more Ancients had ascended and apparently joined their own ancestors who were with The Others; however, no more ascended beings joined the Ori because the Ori did not wish to share their power and prevented their humanity from evolving to the point where they could ascend on their own or through the use of advanced technology. This period ends when the last of the Lantian survivors of the Wraith-Ancient War abandoned Atlantis and used the Stargate to return to Earth, where they blended into Earth's societies, left the planet through the Stargate, or ascended.
Present to 10,000 years ago	Legacy	Possible	Yes	All except original home galaxy.	This is when the majority of Ancients are Ascended Beings, and other races use and abuse their legacy. At the beginning of this period, the Lantian Ancients had just returned to Earth after abandoning Pegasus to the Wraith and chose to blend in with Earth's societies, to leave Earth through the Stargate, or to ascend. Proof of the Ancients' blending into the human population of the Milky Way is the natural occurrence of the ATA gene (Ancient Technology Activation gene) that allows the possessor to activate and interface with genetically-keyed Ancient technology, as well as the cultural influences of the world's ancient civilizations. Some Ancients from earlier in this period survived into the modern era in human form via stasis, time travel, or some other form of technological means, while a few Ascended Ancients chose to retake human form. This period includes the reopening of the Stargate in modern times and a near-repeat of history as the humans of Earth assimilate the Ancients' legacy, which not only includes knowledge and technology, but also old rivalries that the Ancients had failed to resolve. It also includes the discovery of Destiny, which opened up the universe to exploration (albeit limited) and to the exposure to new life forms untouched by Ancient hands.

ca A.D. 2007-2008

This time estimate corresponds to Season Four and into the beginning of Season Five of Stargate Atlantis.

Asurans attack Atlantis; Atlantis gets a new home; Carter becomes the new commander of the Atlantis Expedition; Travelers recover and use abandoned Ancient warship; Earth experiments with Asuran nanotechnology; Asurans are destroyed; Wraith are greatly weakened:

The IOA sent the newest 304 to Pegasus, the Apollo, with the Horizon Weapons Platform to destroy the warships that the Asurans were building on their homeworld. They believed that the Asurans were going to attack Earth, so they decided to execute a first strike against them. Horizon worked, and the ships were destroyed, but the Asurans retaliated by sending a high energy beam against Atlantis through an orbiting Stargate. To escape this beam, the Expedition submerged the city-ship just as the Lantians had done 10,000 years ago, but the beam was still too powerful. Finally, they used the underwater drilling platform to boost their energy to launch the city-ship into space. (Stargate Atlantis: 3.20 "First Strike Part 1", 4.01 "Adrift Part 2")
The power of the single ZPM in Atlantis was about to run out while the city-ship was still in space, so the Expedition decided to steal a ZPM from the Asurans. They used an experimental hyperdrive generator on a puddle jumper to get to Asuras (this hyperdrive was designed by McKay after he had become a superhuman through his exposure to the Ancients' ascension acceleration technology). They also used the nanites inside Weir, which had been reactivated to heal her when she was gravely injured in the Asuran attack. Using Weir's subspace link with the Asuran collective, the team managed to locate and steal a ZPM. During the link, Weir isolated the attack code that the Wraith had managed to shut down and didn't erase. McKay reactivated the code, but during this added time on Asuras, Weir was discovered and captured. The team made it back to Atlantis with the ZPM, which they used to power the city-ship's descent onto a new homeworld. (Stargate Atlantis: 4.02 "Lifeline Part 3")
The IOA chose newly-promoted Col. Samantha Carter, formerly of SG-1, to become the new commander of the Atlantis Expedition. She was selected over other potential leaders because of her knowledge of Ancient and Replicator technology. (Stargate Atlantis: 4.03 "Reunion")
The Wraith captured McKay so that he could shut down the Asurans' attack code. The Asurans had built more warships and were attacking Wraith worlds, and because of McKay's modifications to the Asuran base code, the Wraith's old program to stop the Asurans no longer worked. McKay was rescued before he was able to make any changes to the code. (Stargate Atlantis: 4.03 "Reunion")
Some time ago, a group of humans in Pegasus learned to survive in a Wraith-dominated galaxy by living in spaceships. Their technology was put together from what they scavenged off of abandoned worlds. They were running out of room for their people on these ships, so they had to leave some of them behind "on the ground". When they heard that people were using Lantian technology, they set up spy satellites near the Stargates that were in orbit so that they could catch the pilot of a puddle jumper. This pilot happened to be Sheppard, and the Travelers, as they called themselves, knew that he possessed the gene needed to activate Ancient technology. They had found the abandoned Ancient Aurora-class warship in its two-hundred-year elliptical orbit and wanted Sheppard to initialize its systems so that they could move in. They fixed the harmful radiation leak and got the hyperdrives working again. Sheppard asked that they become allies in the war against the Wraith, and the Travelers' leader Larrin let him go. This new alliance proved to be very beneficial soon thereafter. (Stargate Atlantis: 4.05 "Travelers")
Michael and his Beckett clone, who was coerced into helping, perfected the Hoffan drug to the point that it killed 30% of the human subjects rather than the original 50%. Michael used this drug as the first wave in his bid to gain galactic domination. Because he was shunned by Wraith and humans alike, he waged his war against both by tainting the Wraith's human food supply with the drug. He planned to then convert the human survivors into his iratus-human hybrids. He had already converted himself into this hybrid form through changes in Beckett's retrovirus, eliminating his need to feed on humans, but keeping many of the strengths of the Wraith, including their telepathic and regenerative traits. He needed a lot of test subjects, though, so he kidnapped the Athosians and discovered that some among them had "the gift", traces of Wraith DNA that gave them the ability to sense Wraith through their psychic link. Among the Athosians who had "the gift" was Kanaan, Teyla's lover, and he was one of the first to be converted into a hybrid. (Stargate Atlantis: 4.07 "Missing", 4.18 "The Kindred Part 1", 4.19 "The Kindred Part 2", 4.20 "The Last Man Part 1")
The Atlantis Expedition met Davos of the Vedeenans, who could see future events in remarkably detailed visions, which he was also able to share telepathically. Davos claimed to never be wrong in his visions, but he pointed out that interpretations were highly subjective. Davos was dying, and his daughter asked the Expedition to help him, so he went to Atlantis for treatment. Richard Woolsey of the IOA suggested that Davos be studied because precognition was an ability of advanced humans like the Ancients, but Davos's unique brain structure was determined to be an anomaly rather the result of human evolution. Before he died, Davos told the Expedition that their future actions were very significant for the rest of the galaxy. (Stargate Atlantis: 4.08 "The Seer")
Sheppard's Wraith ally contacted him to obtain his help in shutting down the Asurans, since he knew that the Atlantis Expedition was responsible for reactivating the primary code for the Asurans to attack the Wraith. What McKay didn't foresee when he reactivated the code was that the Asurans would go after human worlds in order to starve the Wraith out. The Wraith ally and McKay worked together to try to rewrite the shutdown program, but their work was slowed down due to the enormous complexity of the code that the Ancients had programmed into the Asurans. (Stargate Atlantis: 4.08 "The Seer")
The experience that the Atlantis Expedition had with the restorative capabilities of the Asuran nanites within Dr. Elizabeth Weir drove the funding of the research and development of nanites that could repair damage inside a human's body and then deactivate once the healing was complete. McKay didn't get the chance to program Weir's nanites to heal, but only to replace damaged tissue. This next generation of nanites were to go that one step further, and McKay hoped that once they recovered Weir, they'd be able to reprogram her nanites. Unfortunately, these man-made nanites proved to be as much of a challenge as the Asurans themselves: they temporarily shut down a person's body to make major repairs, rendering the patient a vegetable upon revival. It took the help of the Wraith ally to stop these nanites, but this programming didn't lead to a solution to the Asuran coding problem. (Stargate Atlantis: 4.09 "Miller's Crossing", 4.11 "Be All My Sins Remember'd Part 2")
The question about who created that nanovirus that killed humans but left Ancients untouched might have been answered when Sheppard's Wraith ally told the Expedition that the Asurans were killing humans. Back when the nanovirus was created, the Asurans had a "do not harm Ancients" code, while their primary function was to eliminate the Wraith. Apparently nowhere in the Asurans' code was there a "do not harm humans" rule. The work on shutting down the Asurans didn't progress after several weeks of trying, so the Expedition's Plan B was executed: send the Daedalus and Apollo out to ambush and destroy the Asurans' warships. They obtained a sensor to detect these ships from a rogue Asuran group who were cut off from the collective because they wished to reach ascension like their Ancient creators. These rogues were influenced by Elizabeth Weir's mind, but they reported that the Asuran leader Oberoth had Weir killed because of this influence. McKay finally came up with the answer to the Asuran problem: call all of the nanites into one place, compress their combined mass on Asuras, and detonate ZPMs surrounding them to destroy the mass. (Stargate Atlantis: 1.13 "Hot Zone", 4.10 "This Mortal Coil Part 1", 4.11 "Be All My Sins Remember'd Part 2")
The Asurans warships returned to Asuras when they lost several lone warships to the Plan B attacks. In order to keep the ships occupied while McKay did his programming on Asuras, the Wraith sent seven hive ships (all loyal to Sheppard's Wraith ally); the Travelers, around five ships, including their Aurora-class warship; and the Expedition, two. While in orbit over Asuras, the Wraith in darts entered the city to steal several ZPMs. (Stargate Atlantis: 4.11 "Be All My Sins Remember'd Part 2", 4.12 "Spoils of War")
In order to get the Asurans to compress into a single blob, McKay needed to program a block of nanites to act as the seed. He found a device on Atlantis that was used by the Ancients to experiment with Asuran technology. This device actually created human-form artificial lifeforms. Unable to override the device's core function, McKay created a female android he named "FRAN", which was an acronym for Friendly Replicator Android. Fran knew that her "life" would end when she met her purpose, but she readily embraced the opportunity to fulfill her programming. She was beamed into the heart of the Asuran city, greeted the surpised Asurans with a friendly "hello", and then activated her destructive program. (Stargate Atlantis: 4.11 "Be All My Sins Remember'd Part 2")
Fran's sacrifice and the joint effort among the Expedition, Travelers, and Wraith worked; the Asurans were annihilated when their combined mass caused the planet to explode. Only the rogue group of Asurans who were disconnected from the collective survived, and they had a new leader: Elizabeth Weir. (Stargate Atlantis: 4.11 "Be All My Sins Remember'd Part 2")
The Wraith ally who took the ZPMs from Asuras was planning to power up the cloning facility to build his own army, but he was betrayed by one of his own. Sheppard's team rescued the ally, whom Sheppard nicknamed "Todd", when Todd sent a locator beacon signal that he knew Atlantis would pick up. At the time of his rescue, Todd told McKay about how the Wraith used this cloning facility with three ZPMs taken from Ancient warships that were captured deep within Wraith territory during the war 10,000 years ago. It was through cloning that the Wraith built their overwhelming numbers and won the war against the Ancients. Todd described the Ancients as "powerful but careless" and said that the Lantians believed that their warships were "unbeatable". The Ancients recognized their major fault in their recording left behind in Atlantis at the time of their defeat: "In our over-confidence, we were unprepared and outnumbered." (Stargate Atlantis: 1.01 "Rising Part 1", 4.12 "Spoils of War")
After Todd's rescue, the team destroyed the cloning facility by crashing Todd's damaged hive ship into it. The three Asuran ZPMs were lost in the explosion. (Stargate Atlantis: 4.12 "Spoils of War")
Sheppard's team visited a planet where the Ancients had once had a mini-drone testing facility. The Ancients also made this place their home and blended in with the human population, as there were those of the planet's current royal bloodline that had the ATA gene. The people developed rituals around the left-over technology, especially concerning the selection of the next queen: The rite of passage for a princess who was to be queen included the activation of the control panel to the mini-drone test firings, as well as the possession of the Pendant of Wairos, the Ancients' security pass key. If the princess couldn't activate the control panel with her touch and the Pendant didn't light up, then she believed that the gods had not chosen her to be the next queen. (Stargate Atlantis: 4.14 "Harmony")
The development of nanotechnology based off of the Asurans continued on Earth, but one scientist went much further than any of the researchers before him and created androids. The male model that he created was for military purposes, and the female model, for social purposes. After the incident with the medical nanites, the scientist's research came under review, so he tried to hide the evidence by deactivating his male model, but "Archetype" escaped. He was caught and beamed into low orbit where he burned up in the atmosphere. The female model, who had the memories of the scientist's dead assistant, was destroyed, but her consciousness was saved by being transferred into a virtual environment in a stasis chamber that had been brought to Earth from one of the Ancients' Aurora-class warships. (Stargate Atlantis: 4.15 "Outcast")
Todd stole the passcodes to the Midway Space Station of the Intergalactic Gate Bridge while he was working with McKay to shut down the Asurans, and one of his lieutenants stole that information from him. As a result, a group of Wraith infiltrated Midway and gained access to Stargate Command on Earth. The Wraith were contained, but the Midway Station was completely destroyed after the Wraith booby-trapped it with the self-destruct. (Stargate Atlantis: 4.17 "Midway")
Michael learned of Teyla's possession of "the gift" and used her relationship with Kanaan to lure her through visions of Kanaan's asking for her help in finding her missing people. At this point, Teyla was close to the delivery date of Kanaan's son, and Michael suddenly became obsessed with the unborn child. He realized that the child of two people who had "the gift" could provide the missing data he needed to perfect his hybrids. Michael kidnapped Teyla, and the Expedition mounted several rescue missions to find her. They used Todd as a source of information in exchange for the Hoffan drug research so that he could save his dying hive. Todd's intelligence led Sheppard's team to one of Michael's facilities where he was holding the Beckett clone. Much to everyone's surprise, the Beckett clone was an amazing duplicate of the deceased doctor himself, but he had two major differences: he was programmed to not harm Michael, and his life depended on a weekly injection of a Wraith regenerative cocktail. His condition quickly deteriorated, and he was placed in an Ancient stasis chamber on Atlantis so that scientists could come up with a cure. (Stargate Atlantis: 4.18 "The Kindred Part 1", 4.19 "The Kindred Part 2")
In his search for Teyla, Sheppard was accidentally thrown 48,000 years into the future when the wormhole he was in was bent by a solar flare. Traveling in time due to a solar flare event was usually prevented by the Ancients' Stargate programming, but the Expedition had made some unintentional modifications to the code when they last updated the operating system that they used to interface with the Ancient technology. Sheppard went home to an abandoned city that was sitting in the middle of a desert instead of floating on the ocean. A holographic McKay told Sheppard what had happened after he went missing: Michael killed Teyla after she bore her son, perfected his hybrid-creating process, killed the Wraith, converted the strongest of the human survivors into his hybrid army, and took over the galaxy; humanity ended. McKay devised a way for Sheppard to return to his own time, but Sheppard had to wait several hundred years in a stasis chamber for the conditions to be right. He was sent back to twelve days after his original disappearance, giving him enough time to save Teyla and prevent Michael's rise. Sheppard and his teams went to the place where Teyla had been found in the alternate timeline, but the entire building was booby-trapped. Several explosions went off, and the building collapsed with the teams still inside. Carter mounted a search and rescue operation, and the Daedalus destroyed Michael's cruiser after he showed up hoping to capture the trapped team members. (2.21 "1969", Stargate Atlantis: 4.20 "The Last Man Part 1", 5.01 "Search and Rescue Part 2")
Teyla had a baby boy, her delivery assisted by a very nervous McKay. She named him Torren John Emmagan, after her father and teammate John Sheppard, who had played a key role in her rescue. (Stargate Atlantis: 5.01 "Search and Rescue Part 2")

ca A.D. 2008-2009

This time estimate corresponds to Season Five of Stargate Atlantis and to Stargate: Continuum.

Carter is recalled to Earth and returns to SG-1; IOA Representative Richard Woolsey becomes the new leader of the Atlantis Base; The last of the Goa'uld System Lords is executed; The Lost Tribe of the Asgard are exposed; The Attero Device is reactivated; Michael is killed; The Wraith reach Earth; Atlantis returns home to Earth:

The last clone of the last Goa'uld System Lord Ba'al was captured by an SG team. Arrangements were made with the Tok'ra to preform an extraction ceremony in which the symbiote would be removed from the host and then executed. Col. Samantha Carter was recalled to Earth not only to witness Ba'al's execution, but also to attend an evaluation for her first year as the leader of the Atlantis Base. She was greeted by the IOA Representative Richard Woolsey at the base of the SGC gateroom ramp and given the bad news that she was being replaced ... by Woolsey himself. Carter returned to SG-1. (Stargate: Continuum; Stargate Atlantis: 5.01 "Search and Rescue Part 1")
The Tok'ra were aware that the hosts were usually unwilling participants in the Goa'uld's actions, so Ba'al's host's clone was spared. In his final words to SG-1 (including Maj. Gen. Jack O'Neill, Col. Samantha Carter, Col. Cameron Mitchell, Dr. Daniel Jackson, Teal'c, and Vala Mal Doran), the clone implied that he was not the last. Indeed, he wasn't. The original Ba'al had built a time traveling machine that predicted solar flares that were used to bend wormholes created by the Stargates. Unbeknownst to all of them, a time traveling Cameron Mitchell had traveled to 1939 and intercepted Ba'al when he boarded the ship that was transporting the Stargate from Africa to the United States. Because of all of this time traveling, the last of the Goa'uld System Lords had actually died in the past. After the clone's extraction ceremony was completed, Vala stayed behind to offer him comfort since she understood his plight after having been a host to the Goa'uld Qetesh herself. O'Neill treated the rest of the team to lunch. (Stargate:Continuum)
When all of the Atlantis Base personnel were on Michael's planet to rescue Teyla and caught in the collapse of the facility, they had all been exposed to a pathogen that was designed to grow a Wraith hive from the body of a human. Dr. Jennifer Keller was the first to show advanced stages of the infection. The engineering of this pathogen demonstrated just how really advanced the Wraith were and why the Ancients described their enemy's level of advancement as rivaling their own. Fortunately, the clone of Dr. Carson Beckett had a great understanding of the process and designed a phage to cure everyone affected. (Stargate Atlantis: 5.02 "The Seed")
The rogue group of Asurans who wanted to achieve ascension had managed to avoid the destruction of Asuras, so they were able to pursue ascension without interference. Their new leader was the Asuran embodiment of Dr. Elizabeth Weir's consciousness. They discovered that their physical bodies weren't able to convert into energy like those of the Ancients, so they devised a technological solution that uploaded their consciousnesses into subspace and destroyed their bodies to mimic the ascension process. This turned out to be a bad idea. Even after they were helped to create new bodies with the machine discovered on Atlantis, they found that their Asuran programming was still too aggressive for them to ever find peace. The replicant that embodied what remained of Weir tricked the rest of the group into 'gating to a Stargate that was in orbit. Thus, the last of the Asurans were left to drift in space forever. (Stargate Atlantis: 5.05 "Ghost in the Machine")
Dr. Rodney McKay was invaded by a parasite that caused him to regress to the mentality of a child. The parasite was discovered too late to operate, but Ronon Dex, a native of Pegasus, was aware of a place formerly of the Ancients that could give McKay one last day of lucidity before dying. The team, Dr. Jennifer Keller, and McKay's sister Jeanie Miller took him to the Shrine of Talus in a cloaked puddle jumper because the planet had become a Wraith stronghold. The Ancient ruins located behind a waterfall emitted a type of radiation that repelled the parasite, thus causing it to withdraw its hold on portions of McKay's brain. Keller drilled a small hole in McKay's head and the parasite made its escape, only to meet its death from a blast from Ronon's gun. The cause and nature of this radiation were never discovered, but it was speculated that it was originally an energy source for a research station. (Stargate Atlantis: 5.06 "The Shrine")
Using Beckett's and Michael's research as a foundation, Keller developed a gene therapy that would eliminate a Wraith's need to feed on humans for survival. Therapy treatments were designed to reactivate the Wraith's human digestive system and remove his feeding organ from his hand, but the rest of the Wraith's body was not targeted. The Wraith that Sheppard had nicknamed Todd was open to try this therapy because it would help his hive survive when all other hives were dying out due to Micheal's release of the modified Hoffan Drug that tainted the Wraith's food source—humans. Teyla underwent surgery to give herself the appearance of a Wraith queen so that she could convince them to follow Todd's lead. They agreed that after Todd was in command for a while that they'd begin the treatments. (Stargate Atlantis: 5.08 "The Queen")
With the defeat of the Ori and the end of the Goa'uld System Lords' reign in the Milky Way, Dr. Daniel Jackson was able to devote more of his time to conduct research into the Ancient Database from Atlantis. The Expedition regularly sent portions of the Database back to Earth. Daniel found clues inside the personal journals of Ancients associated with the inventor Janus that led him to believe that Janus had a secret lab in the city. Finally, he got to visit Atlantis to explore, but was kidnapped by aliens when he and Dr. Rodney McKay found the lab and unwittingly reactivated the key to the Attero Device. (Stargate Atlantis: 5.10 "First Contact Part 1")
The aliens that kidnapped Daniel and McKay were the Lost Tribe of the Asgard, the ones who used the Ancient-Wraith War as an opportunity to conduct their genetic research on humans to solve their cloning problem. They were still victims of the Wraith, however, and ended up taking refuge on a planet with a toxic atmosphere that over the years grew even more so. The Lost Tribe created sophisticated suits and hyperspace-capable ships that were able to penetrate Atlantis' energy defense shield. Once the key to the Attero Device was reactivated, they set a plan in motion to turn the Device back on again and get rid of the Wraith once and for all, despite the side effect of Stargate explosions. McKay, the possessor of the ATA gene, yielded to the threats made by the aliens and reactivated the Device before he knew what the side effects were. Once he knew, he and Daniel had to turn it off by wearing the Lost Tribe's protective suits and entering the Device's radioactive chamber directly. Daniel was injured when he was hit by an energy bolt right before McKay successfully deactivated it. They were rescued, and Daniel was sent back home to Earth to recuperate. (Stargate Atlantis: 5.10 "First Contact Part 1", 5.11 "The Lost Tribe Part 2")
While McKay and Daniel were captives of the Asgard, the Wraith Todd was aboard the Daedalus to review Keller's research for the gene therapy. Having been in the Wraith-Ancient War 10,000 years ago himself, he immediately recognized the effects of the Attero Device when two of his ships were vaporized. Thinking that he had been betrayed, Todd forcefully took control of the Daedalus and determined that he'd destroy the Attero Device before any more of his ships were lost. It was a battle of wills to regain control of the Daedalus, but in the end, it was Sheppard aboard a Traveler's ship who finally destroyed the Device after rescuing his people. Todd left the Daedalus with Keller's research. The Stargate on Atlantis had to be replaced by one from the Intergalactic Gate Bridge since it was one of the Stargates that exploded when the Attero Device was turned on. The Travelers lost an entire settlement and their Ancient Aurora-class starship when their Stargate exploded. (Stargate Atlantis: 5.10 "First Contact Part 1", 5.11 "The Lost Tribe Part 2")
Even though the Atlantis Expedition had done everything they could to use the technology of Atlantis with good intentions, there were several human societies that disagreed with their methods, which were sometimes more destructive than productive. They joined together into a Coalition and put Sheppard and his team on trial for crimes against humanity. Woolsey was able to negotiate with the Coalition leaders, and Atlantis found even more allies in their fight against the Wraith. (Stargate Atlantis: 5.13 "Inquisition")
Michael had escaped from the destruction of his cruiser in none other than Sheppard's puddle jumper, and he returned to Atlantis to capture the city and take Teyla and her son with him so that he could continue his research. Finally, Teyla killed Michael, putting an end to his reign of terror over humans and Wraith alike. (Stargate Atlantis: 5.14 "The Prodigal")
As it turned out, the Sekkari seed carrier that landed in an ocean two thousand years ago had landed on the same planet that Atlantis had relocated to when they escaped from the Asuran satellite weapon. The artificial intelligence in the device reawakened and created illusions in Woolsey's, McKay's, and Sheppard's minds to study them and eventually direct them to help it achieve its goal. The AI showed them what the Sekkari looked like, and then the unit was taken by the Daedalus to its original destination. This unit was the only one of over fifty that actually had a chance in restarting the Sekkari civilization. (Stargate Atlantis: 5.15 "Remnants")
The Wraith Todd tried out Keller's gene therapy on his hive. At first the therapy worked, but then the subjects were stricken with cancer. They sent out a distress call to Atlantis and then placed themselves in stasis pods, but because the hive ship itself is organic, the ship was stricken with cancer as well. Todd was the only survivor and was given his freedom to try out a treatment of last resort: subjecting himself to be fed upon by an Iratus Bug to reactivate his ability to heal. The failure of this therapy spelled the end of any hope that the Wraith and humans could co-exist peacefully. (Stargate Atlantis: 5.17 "Infection")
Another pair of Ancient Communications Stones were discovered in Janus' secret lab in Atlantis. Unfortunately, a thief named Neeva Casol discovered a box of four Stones and the Terminal soon thereafter and ended up swapping bodies with Keller in Atlantis. When Sheppard's team found the Terminal, they had the same problem in turning it off as what was experienced by SG-1 several years earlier when Daniel and Vala were linked to a married couple in the Ori galaxy. Ronon blasted the Terminal with his gun in order to turn it off, but at least the Expedition had the devices left to study. (9.03 "Origin Part 3"; Stargate Atlantis: 5.18 "Identity")
In an alternate reality, a Wraith hive reached Earth, but was destroyed by the Ancient Weapons Platform that had been moved from Antarctica to Area 51. One of the Wraith dart pilots survived, and he disguised himself so that he could live among humans in Las Vegas, Nevada. Using his telepathic abilities, he won huge sums of money playing poker in the casinos. He used the money to buy whatever he needed to build a transmitter powerful enough to send a message all the way to the Pegasus galaxy. He became careless with leaving his feeding victims to be easily found by the authorities, and soon he was discovered. He was killed by this reality's Sheppard, a police detective, but not before he sent his signal. (Stargate Atlantis: 5.19 "Vegas")
The signal that this alternate reality Wraith sent out didn't reach his own Pegasus, but instead, it breached the barrier between realities and made its way to Atlantis' reality. A Wraith that had been with Todd when he took several ZPMs from Asuras stole one and used it to build a "superhive", a large ship with a nearly impenetrable hull. This superhive was taken to Earth and immediately targeted Area 51 where the Ancient Weapons Platform had been moved. Even Earth's Daedalus-class fleet was unable to stop the Wraith, so it was left up to Atlantis to protect Earth. Atlantis was equipped with a never-used-before wormhole drive that permitted the city-ship to travel nearly instantaneously to Earth and to destroy the enemy. With its energy resources drained, the city-ship was forced to land on the Pacific Ocean, where it now sits cloaked not too far from San Francisco Bay. Atlantis had returned home. (Stargate Atlantis: 5.20 "Enemy at the Gate")

After millions of years of traveling into the far reaches of the universe, the Destiny finally received explorers as people from Icarus Base in the Milky Way activated the nine-chevron code that had been discovered in the Ancient Database (from Atlantis) to hurriedly evacuate while the Base was under attack. Unfortunately, the Ancient ship had traveled too far for those stranded there to use the Stargate to dial Earth. Now, the approximately 80 Earthlings must fend for themselves and struggle to survive billions of light years from home in a ship that is mostly damaged and uninhabitable and functioning at less than normal power levels. If it weren't for long-range communication devices derived from Ancient technology and Destiny's accommodating programming to stop at planets that can provide the basics for survival, these people would have absolutely no contact with Earth and no hope of ever returning home.
