Does a template exist anywhere for Pathfinder that gives the feel of World of Warcraft's Forsaken? I ask because I have an idea for a npc that I want to feel like one.
If you're okay going back into 3.5 books, the Necropolitan from Libris Mortis is probably exactly what you're looking for.
In pure Pathfinder, I'd probably do something like the fast zombie ruled to maintain an intelligence score or just build it normally then apply the undead traits. You shouldn't run into too many problems just using it for an NPC.
