P3R-112 is a forested and apparently isolated world which Ba'al used in a ploy to rid himself of the clones that he had created. He had called the clones together on the planet for a meeting on the Adria situation, but once they had assembled, he beamed in canisters of symbiote poison. When SG-1 arrived on the planet, they discovered a group of tents in a clearing and several dozen dead Jaffa. Inside one of the tents at least ten Ba'al clones had gathered around a table, and all were dead. The only survivor of the slaughter was a single Jaffa who relied on tretonin rather than a symbiote, and he reported to SG-1 what had happened. Not all of the clones had been destroyed on the planet, however.
