So I guess ill start out with im a blood mage and well you can say that i'm a little off ...I/e I like to take blood samples and taste them... but well I've made an enemy of some sort of blood demon...that's not in a book so I have a idea that I could trap it inside me (kind of like Naruto in the fact its has a chance that I can take control of me. I was also thinking that I could siphon off some of its ability in some way) so any ideas would be great as HELL
Talk with your GM? Communication helps create new things and avoid rejection.
I once wrote up a character concept for each of the core 9 classes based on demonic presences. A Barbarian who's possessed during a rage, fighter who gains knowledge through pacts, etc. Wizard was bound into an object in the skin and used his flesh as a spellbook using expensive inks as materials to create shifting tattoos and forced the demonic presence to teach him magic. Sorcerer had a demonic bloodline and cast through dark and fatiguing rituals through using his blood as a material, focus, and fuel. Was fun to make them! I should probably do it for pathfinder's new classes sometime.
Anything other details about your own character or what you exactly want? Need details to a concept or mechanics or archetypes?
If you get to have a devil inside then I should be able to have my own personal Jesus.
S'only fair.

No such option exists for daemons, but if you want to make one, it'd be similar to the last two.
