In the world of Greyhawk, Mordenkainen is a powerful archmage of Oerth who leads a group of adventurers called the Circle of Eight tasked with maintaining cosmic balance. Occupying the Tower of Urm, a windowless, iron tower that jaunts across the multiverse, Mordenkainen has authored several planar tomes and crafted many renowned spells, including Mordenkainen’s faithful hound, Mordenkainen’s magnificent mansion, and Mordenkainen’s sword.

Various Travels

Among his planar travels, Mordenkainen often sojourns to Avernus, the first layer of Hell, to study how the Nine Hells affect the schools of magic. Empty iron foundations remain behind to mark the site of his tower’s arrival and upon its return, the tower locks itself into place with a satisfying clunk.
