Asdad

Ba'al's fortress world was a planet where the System Lord Ba'al experimented with gravity technology. He kept it hidden from the rest of the Goa'uld. The planet was a fortress, and the Tok'ra sent Kanan to map out the base. During his time, Kanan had an affair with Shallan, Ba'al's lo'taur. After being implanted with Jack O'Neill, Kanan attempted to rescue Shallan. The plan failed, and O'Neill was captured and tortured. SG-1 sent the location of the planet to Yu, who sent his ha'tak to attack, allowing O'Neill a chance to escape.
