Arc is dying, since the age of ten he was diagnosed with cancer and but with sheer will power alone he forced his frail body to work. In his last few moments of life he decided not to die, he defied the heavens and rose up from its tyranny. When he died his soul instead of going back into the endless cycle of reincarnation drifted out into the void and was pulled by its curiosity to an ancient world long forgotten by the gods.
