At some point in the last hundred and fifty odd years, you died. You died and you left an awful mess behind, perhaps literally, perhaps figuratively, only now, you are getting a chance to set things right. Your character will wake up one morning, in a place significant in their past - their workplace, their old home, a favourite park, bar, café, and so on - with absolutely no explanation of why or how. It will be up to you whether or not they remember who they are at the beginning, but they will eventually have to figure it out, and then go about setting their affairs in order.
The catch is, once you made amends, or righted any wrongs done by you or against you, you die again. Your character cannot know this, but if they cross paths with another resurrected and see them die again they may get the hint. Once you figure that out, it will be up to you to decide if your character even wants to set things straight, they may want to live on.
Its just an idea shamelessly stolen from 'Glitch' that I'm sure many of you recognized, just thought it would make for a good RP. I'd appreciate input as to a possible location, I was thinking New Mexico or Arizona to add the Wild West element but open to suggestions. Any takers?
