Born from the fading nightmarish memory of an occult tome, Eldrenn collects that which is forgotten in slumber. Often appearing as a lengthy humanoid figure to dreamers, it offers to record memories before they teeter to the realm of oblivion from the push Eldrenn's nightmares give. Once collected, it writes them down for its own realm, an endlessly tall and empty library, each floor a reflection of a forgotten place. However, Eldrenn also acts as a ward against that which is forbidden knowledge. Subsuming the mind breaking memories before they utterly destroy those who hold such knowledge. These are kept locked away within Eldrenn's own self, but their influence still takes hold, if only at a snail's pace.
