"Godblood-Iron" Golem (Least)

You are a demi-god! ...

A Level 5 demigod rusting away to nothing in an overlooked corner of the Caverns of Kaligoth. You are already a boss: a miniboss, trapped within a small cavern with an unstable ceiling which USUALLY does enough damage to kill you if the heroes collapse it, but sometimes leaves you stuck under the rubble for hours if not days, sitting there immobilized until either the zone reloads or someone digs out just enough of you to kill you but not to let you fight back...

Oh yeah, that Demigod part? You are made out of Orcish Blood-Iron, but some of the blood you are made from is blood from Armok, the god of blood... You'd think this would give you nifty special abilities right? Hah, NOPE! You get nothing!*
*(...Well, exactly one: you can talk directly with Armok if he ever has his attention on you and sense when he does, that's it: which, FYI, has never happened.)

Apparently killing you starts off some kind of quest string to destroy twenty-seven total progressively more difficult "Godblood-Iron" Golems which if you manage to fully complete it makes you a Demigod of Armok...

The one thing you really have going for you is that your iron body is partially sculptable with a little mana and a lot of concentration you mostly use this to make yourself more dangerous if they don't think to drop the ceiling on you...

So: Hideously unfair player advantage? Check.
A completely awesome backstory that doesn't help you at all? Check.
Trapped in a zone where you can't better your own lot? Check.

Guess its just time to wait for the players...
