The Castle Automatic is a 100+ room, 5-level Metroidvania-style dungeon designed for use with His Majesty the Worm. In the module, players will repair magi-mechanical engines that control the castle's sun, moon, weather, and seasons to overcome its deadly challenges.
Use it as an entire campaign! If you're new to His Majesty the Worm, you can get started with just this dungeon, the core book, and a single tarot deck! Or, slot it into your personal Underworld, expanding the core game with all new talents, monsters, dungeon lords, and magical treasures.
Importantly, The Castle Automatic is easy to run. Puzzles, traps, and combat sites are illustrated and included as handouts to be shown during play. The GM has a dungeon tracking sheet to monitor the castle's current state: mechanisms broken and repaired, time of day and year, and current factions in play. With maps for the GM, for the players, and included on every dungeon spread, it's easy to understand the sprawling space.
