Marwyn is the second boss of the Halls of Reflection, guarding the way to the Lich King's throne room. Once one of Arthas' lieutenants, he and his friend Falric turned to the Scourge when their prince took up Frostmourne, and now guard the way to his inner sanctum. Marwyn becomes active on the tenth and final wave of the gauntlet of ghosts spawned to block intruders (which are also based on Human units from Warcraft III), and must be defeated in order to proceed to the Shadow Throne.
