P'Jem was the site of a Vulcan monastery on a planet near the Andorian system. Master Haadok, along with other Monks, founded the monastery almost 3,000 years ago.

In the 22nd century, the monastery was ransacked three times by the Andorians looking for a suspected sensor array. On the last of these occasions, in June of 2151, the Earth starship Enterprise NX-01 visited P'Jem, only to find it taken over by a group of Andorian commandos led by Commander Shran. After some initial misunderstanding and a firefight, the commandos and the Enterprise landing party discovered a highly sophisticated surveillance installation in the catacombs beneath the monastery. Captain Jonathan Archer gave scans of the facility conducted by his science officer, T'Pol, to Shran as evidence of the Vulcans' spying.

The Andorians gave the monks and surveillance personnel ample warning before they bombarded P’Jem from orbit, destroying the monastery.
