I like it. I may be willing to join, assuming you'd let the players make up some lore for their own characters.

I was thinking a sort of "barbarian", though personally he's more like just a guy who just never lived in a city or town for long. He raises dogs for hunting and guarding, and has his family's battleaxe from back when they were "barbarians". He's technically a poacher and not really a citizen of the nearby city/nation/whatever cause he never pays his taxes, and because of that he's a vagrant. It helps since he knows about the creature hunting him down; a mind-controlling, shapeshifting demon. She (though technically genderless it often takes the form of a woman) is not just trying to kill him, but take his soul so she can turn his body into an undead thrall and increase her own power by consuming his soul. This demon is also technically his mother (And grandmother, and great-grandmother, etc), because the way she steals your soul is through sex. His past fathers failed to slay the demon before she got to them, and now it's my character's turn to try to end his curse or end up an minion to her as well.

Possible enemies include: Wild animals, guardsmen who don't like barbarians/vagrants, his own undead ancestors, his former tribesmen (The one who raised him but for reasons he left on bad terms), and of course the demon herself. All my guy has is his family's axe, his own dagger, a pack of dogs, and the will to live. And just about all of those things are much more fragile than they appear.
