Adventurer's Guide to Jeusung From the back of the book: Within this treasured tome, you will find a complete fantasy campaign setting deeply inspired by the richness and beauty of Korean culture and history. You will be able to explore four uniquely detailed lands within the continent of Jeosung. Roam the mystical forest wilderness of Mudangguk or head to the city and meddle in the mercenary politics of Daewanguk. Heroes (or fools) may attempt to infiltrate the hermit kingdom of Haenamguk or brake the frigid peaks of Noonnara.
