Zhekkt and his companion Cheeve 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 Sailor-Eater.
Zhekkt was the larger and paler of the two. He had a thick body seemed sluggish next to his energetic partner. He was very thoughtful and slow to speak, carefully considering his words. He often acted as translator for Sailor-Eater as the later lacked a traditional language.
