Glowering amid dark rumours and terrible stories of desperate adventure, death, betrayal and glimmering treasures squat the unutterably ancient halls of Gloamhold. This crumbling, benighted, haunted dungeon complex of unknown, but undeniably vast, extent is buried deep within the grim and brooding spray-drenched headland of the Mottled Spire. It is a place of legends, madness and death. Within this towering, wave-lashed shard of limestone lies the labyrinthine passageways and chambers of Gloamhold's outer reaches and, beyond them, the benighted precincts and canals of the legend-shrouded Twilight City. Gloamhold is designed for use with any edition of the world's most popular role-playing game.
