Karthus was born into abject poverty in the sprawl of dwellings built in the walls of the Navaria. His mother died at the moment of his birth, leaving his father to raise him and his three sisters alone. After being surrounded by countless deaths Karthus receives the death system. A system which aids him to become the strongest death adept. With this Karthus’s mission is to bring the joy of death to mortals, an apostle to the unliving. The living fear the eternity of undeath, but Karthus sees only beauty and purity in its embrace, a perfect union of life and death.
