Soul Master

One night you were peacefully reading in your room, when suddenly someone you don't recognize appears, holding a knife. You are killed, but you wake up in a mysterious place. The walls are dark grey and on one side, there is a gateway to a beautiful place. On the other, a dark staircase with the air around it tinged with a dark red of fire. You have become the soul master, the one who decides whether people go to Heaven or Hell when they die. Each soul that comes by has a percentage you can see that shows how good they were. If it's more than 50%, they go to Heaven. If it's less, Hell. Your job isn't hard, but after years, you start seeing people you know. Your parents, your siblings, your friends. Most of them end up going to Heaven, which makes you happy. But your smile fades as you see a familiar soul approaching....the person that killed you.
