The Folly of the Gods
Dragonborn paladin twisted by Orcus's evil taint.
Keegan was once a powerful and prestigious warrior, leader of Reveloth Keep. The taint of Orcus, welling up in the rift deep in the keep, began to taint the paladin, and he eventually went berserk, killing all those inside the keep walls, including his son and wife, Ewan and Jana.
When the Bizarre Force entered the keep to close the rift, they awoke Keegan from his eternal slumber. Blinded by hatred and madness, Keegan struck out at them. The Force managed to end Keegan's undeath and bring his soul to peace.
