The Wail of the Deathrattle

We are just toys of the ancient gods. The ancient gods slept and stitched the two worlds together, and monsters appeared in the human world. The deathrattle wails, what it wants to see is a fight between humans and monsters. When the ancient god regarded the two worlds as chessboards, it also became a chess piece. If the ancient god was a general, the only person who could kill the general would be a pawn.
