Reaper as a Human
[Truly Open-World] You've guarded and guided the afterlife for all your time and now the ones above you have decided you've finished your job (they got a replacement). They sent you into the mortal realm to live a life and to die. Memento Mori
You have been the guardian and guide of the afterlife for all your existence. Something no mortal should comprehend. You've guided and weighed countless souls throughout many eras, from mere workers, to people that proclaimed themselves gods, to people studying things they don't know even exist, like magic or some alchemy. You've seen it all but now... The ones above you... They decided you've done your job, for what reason you don't know or you've simply forgotten already. They decided to give you a way of end that's either a miracle or the worst thing that could've happened to you. They sent you to the mortal realm. "Live a life and die." they had said to you.
