"Summoned by the Dark Abyss, the Gem of Eternal Suffering awaits for the master who will claim its powers. The waiting shall bring the Keeper the strength of the Barlog Dragon. Let shadows overpower the bringers of light. Let darkness hollow the souls of justice. Let the etenal suffering begin."
-quoted from The Rise of Shadows
