The 69th Layer of Hell - Lust. Succubi and depraved women roam the fiery pits of this layer in search for men to punish. In a more secluded part, near the western pits, Hyrra rules over the Scarlet Castle.
Here, other rules apply - be it stamina, hunger, exhaustion - those do not exist within these walls. Hyrra and her succubi spend their days sating their neverending hunger.
