Lyonesse is a realm in the world of Dagorhir, a LARP, or Live Action Role Playing game, based in Shawnee Mission, Kansas.
Simply put, Dagorhir is a way for people to be who they have always dreamed of being. Some of us dream of being noble knights from faraway kingdoms, others brave barbarian warriors or evil creatures. Dagorhir is a way for us to do that, and to fight in a safe, controlled setting.
