This world is ours, but it's not right… Holy God's willingly became corrupted, Demonic became good unwillingly, Neutral became shields to keep things alive. A soul from a peaceful timeline, a body from this time with soul fragments of the same but different person. Limbo is a place of spiritual significance, playing a game with those who walk neither Light nor Dark. How a soul thrown six hundred years into the future can survive, I don't know. But at least they have a gun, and helpful friends and new family. Just Limbo didn't plan out things very well due to how this soul ended up.
