My question about the Kemmlerites, and like abstract ideas of sponsored magic, is how do you adjudicate the 'Agenda' of the 'Sponsor' for debt compel purposes?
Right now, to me, the scariest part of the whole Kemmlerite thing is this simple question. If your patron is Death Itself, how do you pay back... Death?
What are you going to have to do, to make Death 'Happy' and feel like He/It/Whatever isn't getting short shrift in bargaining/sponsoring you etc?
Is this a literal personified manifestation of death? Or is this more abstract like, say, they know they just need massive ammounts of necromantic death energy to fuel their necromancy, and debt points reflect a need to 'refuel' their necromancy by doing 'Bad Stuff'tm? It is left a bit nebulous as to how this would function.
It begs the question how to the translate this more abstract envisionment of 'Sponsored Magic' into other types of similar traditions. ( See my Sponsored Magic: Summoner post. )
