Deep in the shadows of the Estorian seas, Crithians live a peaceful, utopian existence. When a poison they call the Blackness kills the sea creatures and destroys the waters, they are forced to unite and use immortal gifts. The sea kings daughter, XANADA, is thrust into a world of chaos when she uncovers the truth surrounding her birth. Her fate collides with NEMESIS, a realm walker fighting to gain her trust while covertly submitting to evil. Estoria plunges into chaos, with Crithians, mortals, the undead, and the gods all fighting for one ultimate power, a power that is XANADAS birthright and one she must learn to control before the Blackness turns both land and sea to ruin.
