Qikost

Qikost is one of the two moons of Sanghelios, along with Suban. Qikost is slightly larger than the Earth's moon.

A group of Sangheili merchants living on Qikost engineered the Concussion Rifle, a weapon which was later incorporated into the Covenant arsenal and remained in use as of the Fall of Reach.
