Merchants of Qikost
The Merchants of Qikost are a group of Sangheili merchants who reside on Qikost, one of the two moons of Sanghelios. The Merchants have been forging weapons since before first contact with the San'Shyuum. They are the manufacturers of a small number of weapons and vehicles used by the Covenant. The designs of these items are of Sangheili heritage, and predate the formation of the Covenant.
After the destruction of High Charity and the collapse of the Covenant, the Merchants began producing materiel previously manufactured by the Covenant's Assembly Forges; these include the Type-33 fuel rod gun.
