Rhimmom Dannihyr was a male human rogue who was the leader of the Shadow Council of the Shadow Thieves.

Rhimmon arrived at this position because he was at the same time the iltarch of the Council of Six from 1362 DR. In truth, the founder of the Council of Six, Thayze Selemchant, made a deal with the Shadow Thieves for use of them as intelligence agents for Amn in exchange for protection against the guild's enemies.[1]
