Stats
Lore
The harbinger of oblivion, Karthus is an undying spirit whose haunting songs are a prelude to the horror of his nightmarish appearance. The living fear the eternity of undeath, but Karthus sees only beauty and purity in its embrace, a perfect union of life and death. When Karthus emerges from the Shadow Isles, it is to bring the joy of death to mortals, an apostle of the unliving.
