The city of Atrine lies in ruins. And now Relos Var has revealed his plan to free the monstrous god, Vol Karoth, the end of the world is closer than ever. To buy time for humanity, Kihrin and his friends need to convince a king to perform an ancient ritual. The power released would imprison the god for an age to come. But this may come at too high a price for the King of the Vane, as the ritual would strip his people of their immortality.
