A shadowrunner essentially is a sinner, although sinless. When they die, they are surely going to hell. The only way out of hell is to possess someone.
Now since Shadowrun has alternate universes and spirits, there must be some creative way to turn a dead character into a spirit, which can possess someone alive.
I want to hear your creative ideas on how I could turn this concept into a playable plot. And what kind of rules would you use to have a character possess an NPC?
And for a fun twist, a character could maybe possess another player's character.
I was thinking maybe having all the players part of a cult of some sort. While they are alive, they would need to bind their souls to someone or something which would give them a "link" so that they can guide themselves out of the spirit world. Kind of like drowning, but saving yourself by pulling your self up by holding onto the anchor chain. Although when you get out of the water, you will no longer have your old body available for use and will need to find a host.
I want to hear ideas.
