Cheeve and his companion Zhekkt were wandering Chuuls. Their master, an aboleth named Oolthooroon, the Greatest Mind, vanished some time ago, leaving the Chuul pair to wander the sea floor looking for another strong mind to serve. They eventually fell into the service of the ebi-kreen "Image of himself eating a drowned sailor" who treated them as little more than pack mules. They briefly served Kimchiwei, while traveling in the City of the Holy Dragon as Kimchiwei's mental abilities vastly outstripped Sailot-Eaters. Cheeve took a strong liking to Jin the Dokkabi and allowed the goblin to ride him like a mount.
Cheeve was the smaller and darker of the two. He had a slim body and very active pincers. He was always a bit snappy and eager to engage in energetic conversation, although he was clearly less intelligent than his brother.
