Some time before Teal'c joined SG-1, whilst under the command of Apophis, the local population of P3X-887 tried to oppose Apophis. Apophis' forces initially attacked them in a great walled city standing on the edge of a cliff and were able to slaughter all who lived there, forcing the population to retreat to a village where they stood their ground as their last attempt to survive. Nevertheless, the Jaffa under Teal'c's command killed every being on the planet, leaving it a barren world devoid of sentient life.
Four years after joining SG-1, Teal'c and his team once again visited the planet after Stargate Command had sent an Unmanned Aerial Vehicle through to scout the area surrounding the Stargate. Scouting the area, the team were able to confirm that there were no signs of life or energy readings and simply put it on the list for cultural exploration after seeing possible signs of Minoan culture in the ruins.
