Blood and Ash

"You're not in the human world anymore. I don't know why you came here, but you've made a grave mistake. This world is full of vicious and bloodthirsty monsters that would love nothing more than to see you dead and kill you themselves so they can take your soul and get out of here."

Your first goal is to survive. Your second goal? Escape.

Luckily, you come across a stout skeleton who wants to get out of here just as bad as you do.
