The Necromancer's Tower

Publisher's blurb: Here's another quickie: a necromancer and his decrepit abode. The "necromancer" in question, Averhaz, is from 1995, and was apparently created using the D&D Rules Cyclopedia. (The non-weapon proficiencies are a dead giveaway.) If you've been looking for a random evil fiend and his lair for your game, look no further.
