You were going happilly about your life, minding your own business, when all of a sudden, you died. Bummer.
But then you went to heaven. Or at least it looks like you did.
Somehow it seems things didn't work the way they should and you were shoved into a fortress in the middle of nowhere.
Now there's nothing you can do but play along, the guys at the fortress are pretty easygoing anyway, everything should be fine. It's not like this is an actual fortress, right?
