Located between Horizon and Santa Cora, the once-splendid golden dome that served as the stronghold of the Great Golden Wyrm lies in ruins, destroyed in the centuries since the current Great Golden Wyrm threw itself into the The Abyss.
Paladins of the Golden Order make holy-war pilgrimages to the ruins on the mountain, periodically clearing them of monsters and ensuring that no dungeon can rise up into the rubble. But attempts to fully rebuild the Citadel have failed, partly because of concerted attacks by The Three, and partly because the Great Golden Wyrm has ordered the Golden Paladins to disperse through the world instead of remaining near the Abyss.
