Swann Castle (Troika!)
A multiversal setting for fantasy roleplaying, centered on a majestic fortress where travelers from countless worlds gather. The book details the castle’s history, government, culture, queen, ministers, inhabitants, and locations such as the Catacombs, Market, and S’Otel. It includes encounter, rumor, and item tables; new character backgrounds; and descriptions of eight worlds, from Oz to Xöthma-Ghül. Character statistics use TROIKA! rules and can be adapted to other roleplaying systems.
