I that. It doesn't sit all that well, but I still like it.
I like how it kind of means that the demon feeds off the tamer's will -- since I image that, in a normal possession scenario, the opposite is true: the demon is hampered by the host's will.
Somehow, the tamer's got to make it worth the demon's while. If they get a power up, that would work. c:
I'm still bothered by the idea of a demonic contract though. (How does that work?)
