P7S-441 is a forested world with grassy plains and a few deserted structures, although no inhabitants were encountered. When Kaiael, a Reol, had been captured by the Goa'uld for study, he escaped and crashed on P7S-441. There he encountered SG-1 and used a chemical defense mechanism to convince them that he was a teammate. As the team made their way back to the gate, they came under attack by Jaffa, and Kaiael and O'Neill were trapped behind enemy lines, fighting off the Jaffa until reinforcements could arrive.
