==Geopolitical Structure and History==
P9X-391 was sandy and very windy.  Few structures survived the intense wind erosion from those conditions.  When SG-1 visited the planet, they found a strange cylindrical device in one of the antechambers of a ruined building.  When Jonas Quinn touched the device it activated.  SG-1 brought the device back to the SGC for further study.

Later, they realized this device was making them see alien creatures that could pass through solid matter.  SG-1, sans Col. O'Neill, attempted to counter the effect first by disabling the device, then by returning it to the ruins of P9X-391.  When that had no effect, the team returned back to base with the device.
