Light, Blades and Powder

When a person dies, their soul goes only God knows where. For me, I would have never guessed it was back to the land of the living. I wake up in the coldest place on Earth, wearing an outfit I know for a fact was not normal in my previous life, with no exact memories of said previous life, and a knack for weapons I've never used AND I HAVE SUPERPOWERS? Hopefully, with my Ghost by my side and a few pointers from the right people, I can found out what I was, and what I am now exactly.
