"Deep in the bowels of the Black Tower dwells a wicked and contemptible sorceress: Quintessa - The Maiden of Pain! Her depraved arcane machinations seek to drown the realm in her devious debaucheries, but such maniacal machinations require energy! Erotic energy, to be specific...the kind only a creature of insatiable sexual hunger can provide!

But, Quintessa has many plates to juggle, and can't be arsed to handle it all...that's where you come in..!
