Life Eternal

A necromancer awakens in a dilapidated tower he once knew as a pristine stronghold for his lord and sorcerer that he was apprenticed under. Somehow, the necromancer slept through it all in a sleep so sound, not even his lord's death woke him up. But that's all right; his lord had foreseen this coming and made sure the necromancer had the knowledge and training so he could raise his dead lord all on his own.
