Mordenkainen

Mordenkainen was a prolific archmage from the world of Oerth who was responsible for many powerful and useful spells.

Relationships
Mordenkainen was an acquaintance of Elminster Aumar; the two met on numerous occasions at Ed Greenwood's house on Earth to exchange spells and lore.

History
Although Mordenkainen resided primarily on Oerth, by at least 1367 DR, his spells were not uncommon among spellbooks in Faerûn.

Mordenkainen later traveled to Barovia in an attempt to free the local population from its vampire darklord Strahd. However, he underestimated Strahd's power and, after barely surviving a confrontation with him, he lost his spellbook and his staff, eventually losing his memory and being driven to the brink of madness. He became known by the locals as the Mad Mage of Mount Baratok.

In 1491 DR, Mordenkainen, still suffering from bouts of madness, was in Waterdeep, where Elminster was helping him to recover from them.

Rumors and Legends
His toenails appeared to be a venerated item in some places.
