I've had an idea bumping around in my noggin for awhile about a new plot involving a necromancer and a person fated to die.
(You know, typical Canta angst, but bear with me).
The necromancer is in love with the fated person, and each time the inevitable happens to them, the necromancer brings them back, and each time they return, there's a little less of them, their soul, in them. They eventually become an abomination, a shell of their former self, but the necromancer cannot let go, can't see past their own selfishness and love to allow the natural thing to take place.
I haven't decided if I want it to be MxM, or FxF, or something else. But it's bumping around in my head something fierce.
