Obadiah Von Tenebrin is the former headmaster of the House of Conjuration at the Windrest School of Magic and grandfather to Landis Von Tenebrin.
Obadiah left his position at Windrest to investigate the Dooms, during which time he took on the persona of Darvell Snowleaf, a rich merchant. Obadiah was able to infiltrate the Dooms in the City of Alagon, where he became part of the circle of a Doom known only as Chaos.
The Dooms became suspicious of Obadiah, and he had to flee the city. Obadiah was captured by a Doom known as Onyx and later freed by the party.
Obadiah has returned to Windrest, where he has taken a position as a professor while he assists the party in determining how to deal with the next Gathering’s unwanted visitors.
