Mok'slyk

Mok'slyk is an old Flan name for an entity known as the Serpent, an entity of godlike power believed to be the personification of arcane magic. The Serpent is said to be a member of a group of unfathomably old entities known as the Ancient Brethren, which, though similar to gods, are not exactly gods, though some beings honor them as such. The Lady of Pain, Asmodeus, and Jazirian are also sometimes said to belong, or to have once belonged, to this group, and supposedly Vecna is a descendant of the Ancient Brethren. There may also be a connection between the Ancient Brethren and the draedens and baernoloths born before the multiverse began.
