There is unease in the demonic astral plain these days. The Nothern king is dead, and the prince is about to rise to the throne. But he is a strange silent lad. Human commoners (like me) have nothing to do with the local intrigue. Yet...somehow I am now in the very epicenter of this revolution?! Having made a contract with a suspicious demon...I just want to go home! Or in the very least, survive this mess. So please... tell me something!
