The Dome of D'Sparil

The Dome of D'Sparil is the final episode of Heretic. After killing the Maulotaurs at the Portals of Chaos in the Hell's Maw, Corvus enters a giant portal to an ancient castle at the bottom of the abyssal ocean, protected by gigantic crystal domes and overrun by monsters. This is D'Sparil's strongest fortress, for it is where he resides.
