The Things are going to Hell Ending is an Ending in Prisoners of the Elder One. It occurs after using the Transfigurative Orb on Aubrey.
Aubrey intercepts the magic, and instead uses magic of her own to shape Erik's body, turning him into a flatchested Imp. She takes her to Hell, where she spends her days running from more powerful demons. Eventually, she rises the ranks to become a proper succubus.
