P2M-903 has been used as a base of operations by Ba'al. The forested world has a level rocky opening where the stargate has been placed, and a pyramid nearby acts as a landing pedestal for Ba'al's mothership. After the fall of the Goa'uld System Lords, Ba'al attempted to rebuild his empire by using brainwashing techniques on members of the Jaffa High Council. He kidnapped Teal'c and held him aboard his mothership on P2M-903. His attempts to brainwash Teal'c were unsuccessful, however, and SG-1 led a rescue mission to the planet with aerial support from Bra'tac in an alkesh.
