Ideas for Undead Wizards

Refer to this page.

Given that the setting calls for a background where there were many wizards that ruled city-states, I like the two 10 HD undead that were mages, one a snake man lich (Xiximanter the Lich), and one a ghostlike wraith-spirit (The Umbral Duchess). I can work with that.

Honestly, some of the embodied undead that are low-level are  really awesome, too.
