The Umbrium is the lower half and secondary seat of the Solunarian Capital and one of the dual-cities that comprises Solunarium Proper. Before the rise of Aværys, mining revealed the site of a ruined, underground city which they dubbed Oblitium “The Forgotten City”, the foundations of which were incorporated into what is now The Umbrium. Warmed by the magma that churns just behind the walls, the Umbrium houses the Palatium Umbrarum (The Shadow Palace) which was constructed directly beneath its sunlit counterpart, the Blazing Palace. This palace serves as the primary seat of government when the sovereign is moonborn, and houses the headquarters of The Silver Sentinels.
