The Forked Pyre in Hell's first layer, Avernus, is the mighty iron fortress of Duke Furcas. The fortress is built upon a powerful cascade of roaring lava atop the volcano Barrowsiege within the Hanging Marches, Furcas' infernal realm. One of its three spiked black towers houses the burning armories of the duke; the second holds the barracks of the duke's 20 legions; and the third contains a dungeon packed with tormented rivals and useful souls. On an island upon the lava flow at the heart of the duke's palace, rests the six-eyed, hellmouth called Gissiclis, its bowels stretching to the Garden of Heresies in Dis.
