In 2276 the inhabitants of the planet Artaleirh went into open revolt against the Tricameron, declaring itself "Free Rihannsu" territory. The USS Enterprise and ChR Bloodwing traveled to the system to aid in the uprising, and defeated a Grand Fleet pacification force and a Klingon Defense Force invasion fleet in the Battle of Artaleirh.

The Artaleirh system was primarily uninhabited rocky planets and gas giants of various sizes. The system's asteroid belt bore considerable mineral wealth, including dilithium ore, and by 2276 a dilithium cracking station had been built there to exploit it. During the Battle of Artaleirh the defenders took advantage of the ore's explosive properties to destroy ChR Esemar and ChR Llendan.
