Powell IV of Raxxe

This is an excerpt of a room for a dungeon of sorts I'm working on. An undead sage, caged in the crypts of a haunted manor. The table of bizarre books can be helpful for other games, and as a boon you can roll and generate Powell's books at the end. The effects and value of the books are left open, for the Referee to fill in.

• Powell IV of Raxxe, a deceased member of the family. Spent his life alive traveling every corner of existence, until reaching the status of illustrious sage.
• Now an undead abomination; a living skeleton imprisoned within a silver cage at the end of the corridor, a place that he can’t leave by his own. The door is locked and magically trapped. Someone in their true form has to intervene! Said cage has prevented the minions of the Underground King or the Hive Ensemble to get to Powell.
• Powell is spying on anyone passing through these crypts, especially the Hive Ensemble. The sage feeds this information to his great great grand nephew Ludwig of Raxxe, who he sees as a younger (and more alive) version of himself.
• He has numerous self-authored books scattered within his cage. Spending a turn successfully investigating yields D4 interesting books (choose a row for each, or roll 3D6): 

D6	Book Title	Book Subject	Why Powell loves it?
1	The Tortle Lich	The Snail Wars and its aftermath	Cosmic dilemmas
2	Revenant Greed	How to preserve undead bodies	The book’s pages smell...
3	Platinum Sisters	Dwarven Macroeconomics	Terse prose. To the point.
