Translated as 'Knights Home', Ritterheim is a large castle constructed in the center of Salem, serving as the permanent residence of the Audrian Duke and his family. The castle is one of the largest ever built, with multiple layers, defensive walls and towers. The castle can withstand a lengthy siege and offers significant defenses against would-be attackers, ranging from boiling oil, ballistae, and more. On the top of this great keep sits the Black Cross, perhaps the most valuable artifact ever recovered by the Knight-Brothers, which possess holy powers.
