P3X-984 is a world of scattered forests and rocky hills. Because its address was unknown to the Goa'uld, it was chosen as the location of the Alpha Site, the off-world base established by the SGC. The secrecy of the base was strictly guarded, and it became a sanctuary for refugees among the Rebel Jaffa and the Tok'ra. However, the undetected presence of an Ashrak and the deaths of Ocker and Artok fed the hatred and distrust between the Tok'ra and the Jaffa until the Ashrak was apprehended and eliminated, keeping the location of the base secret, and bringing about the beginning of a temporary alliance between the rival races. When Anubis captured Jonas and accessed his knowledge through the use of mind probe technology, the location of the Alpha Site was compromised, and the base was relocated to a new world by using a Tok'ra ship to transport the stargate to a planet with a completely new address.
