The Idra'kess are a group of naga found in Shimmering Expanse. They collect individuals to mine pearls in Nespirah. They are led by Overseer Idra'kess. They appear to be one of the three castes in Vashj'ir, likely focusing on slaving and overseeing.
They are known to train deepseeker crabs as battle companions.
Following the death of the overseer, Nespirah is able to regain control of its body and proceeds to attack the naga as the adventurer escapes. The status of the Idra'kess after receiving this critical blow is unknown.
