Tolok was a respected leader among the Rebel Jaffa, apparently one of their High Priests. He was formerly in the service of Heru'ur (based on his forehead tattoo) and was instrumental in leading the battle for Dakara which saw the Jaffa finally obtain their freedom from the Goa'uld. He was introduced in the episode, 8.16 "Reckoning Part 1".
Tolok coordinated much of the communications among the Rebel Jaffa during their final vie for freedom. When the Replicators entered the Milky Way Galaxy and started to attack the Goa'uld and Ba'al sent his fleet to fight them, the Rebel Jaffa realized that the opportunity to take the temple on Dakara was available and most likely would never be again. Dakara was deep within Ba'al's territory and was considered sacred to the Jaffa because that is where the first implantation ceremony was conducted which created the first Jaffa, but because Ba'al had dispatched the majority of his fleet, there were very few ships guarding the planet. Tolok listened to Teal'c and Bra'tac as they presented their plan, some Rebel Jaffa believing it was suicide, but, finally, when he spoke, he recognized the wisdom of their words and agreed that they should take the temple. (8.16 "Reckoning Part 1")
He led a portion of the Rebel Jaffa fleet into hiding behind the moon of Dakara so that there would be Rebel Jaffa left to fight another day in case the battle with Ba'al's fleet did not go well. After the battle was won and Ba'al fled, Tolok performed a ceremony in which he named Teal'c of the Tau'ri and Bra'tac of Chulak as blood kin to all Jaffa. (8.17 "Reckoning Part 2", 8.18 "Threads")
