Tartarus, warden of sin

Tartarus, the primordial being that watches over the souls of the damned. Governing it's abode, that shares it's namesake, within the lowest pits of the abyss. A prison for the defiled to suffer within the void for all eternity, even clasping the Titans themselves within irons and locking them away from the light. A figure of both fear and of order, a monster that serves the greater good.
