Alright, here me out. 

I want to play as Spirit, you know that cool detective who was thought to be dead?
But here is the difference. he did die, not only that, but horrible. He is a Literal spirit and thus cannot be affected by the physical plane, but can be seen and heard, or even smelled. His driver is the rower of the river styx, and he uses horror and threatening to get what he needs.
