Hello there.

I've kind of an idea for a character where he's a man who is a prison of living flesh for an awakening avatar or behemoth of an old one that is slowly cracking as that power worms it's way out.  The man means well but is simply overjoyed by the act of destruction.  His body is rife with seemingly random tattoos but they infact spell out arcane and unholy rites so that anything destroyed or blood spilled is a sacrifice unto the Old Ones.  He uses his bear hands for this purpose.  

Might even make him Dratha or some kind of mutant bred for this purpose.
