I need help finding/remembering a Template...(Rich, stay out!)

[Kealios]

I thought I remember reading a template in one of WotC's Monster Manuals, Fiend Folio, Ghostwalk, Sandstorm or Frostburn, Tome of Horrors or ToH2, or maybe Monte Cook's Book of Eldritch Might (these are books I read, so it probably wont be something other than these)--

It is a template where an undead gets body parts grafted onto itself from other creatures to make itself stronger.

Basically, I want an imprisoned NPC, stuck in the bowels of a horrible evil temple, to be stuck when the rest of his party is wiped out. Slowly, stuck in the horrors of this one room, he is cursed and becomes an undead. The insanity in his mind drives him to cannibalize the bodies of his fallen comrades, and one by one, he augments his body with their pieces until he is nearly no longer recognizable as human. Here he waits over the centuries, stuck in a vault where he cant get out...and it is here he will meet his PC rescuers. If they only knew...


I can make tihs up, but I swore there was a template like that. Can you prod my mind some?

Thanks,
Kealios

Libris Mortis , perhaps?

*nods in agreement with Talmun* The undead grafts in Libris Mortis sound like what you're after.
