Curse of The Death God

My name is Celeste. I am one of Nine Muses' disciples. Of course, this story is not about me but about my best friend, Edward the Moon God. He was the youngest Celestial Prince who had hold military power since young. Unfortunately, the Moon God was destined to assume the throne of Death God after his power ascending, and live a cursed life of utter loneliness. Edward originally had never mind about his destiny but Edward's misfortunes started at his five thousandth birthday banquet when the current Death God broke free from Underworld and created havoc. This long lost Uncle apparently was involved with lots of mysteries regarding rebellion from five thousand years ago, as well as numerous murder attempts and betrayals from Edward's subordinates.
No matter how much clues he had managed to obtain, Edward's enemies had been always two steps ahead of him. As Edward was helplessly dragged deeper to the eternal enmity between Heaven and Hell, his family's hidden secrets were also being revealed one by one. But, why then he was put under house arrest? Was Edward really the one who plotted rebellion with his uncle against his own brother Crown Prince and father Emperor? What was the truth behind the curse which would soon befall on Edward and had taunted two generations of Death Gods before him?
