“By the grace of Solis, all shall be welcome” “By the will of Solis, all shall be equal” “By the hand of Solis, all shall be safe” “And so the night shall not consume us” Promises made and promises broken, words that spelled the death of an entire civilization. Abducted from the surface and trapped below, a world bent to the maniacal will of the Sun-King. For half a millennia, this world remained sealed until now. What slithers and lurks in the dark after such a time? Ave Nox is a system-neutral mega-dungeon of forgotten history and disaster buried deep in the dark of the earth. Players take on the role of sanctified archeologists, opportunistic delvers, or despised grave-robbers, all converging on a massive newly unearthed ruin. What starts as a curiosity turns into a grand expedition as the ruin reveals itself to be a subterranean megastructure, complete with ancient technology, strange treasures, and still-living agents of the Sun-King… Cunning and curious adventurers may overcome the dangers and unravel the mysteries of this place, yet a greater peril awaits in the farthest depths. Deep in the dark, the Sun-King plots his apocalyptic return, one that will bury the world above in a tidal wave of fire and darkness.

Aqua Regia is a module for His Majesty the Worm, by Joshua McCrowell, produced as part of the Worm Jam in September 2024. Apart from the bestiary, which is specific to the system of HMtW, this module is also compatible with the majority of OSR games. In search of an alchemist who has been missing for years, the characters find themselves caught in a time trap, where two factions are waging an eternal battle: who will win between the Green Lion cultists, who want to kill the Sun, or the Solar Angels, who are determined to wipe out this pathetic sect?

Below the surface of the City is the Lower Ossuary—an underground temple that houses crypts and shrines to the four cardinal virtues: Temperance, Fortitude, Justice, and Wisdom. The temple is currently befouled as the City-dwellers have routed a sewer through it. If the adventurers can cleanse the four shrines, the encroaching Underworld might be driven back. However, something dwells at the center of the Lower Ossuary. Something wicked. Something that can’t stop laughing. This dungeon is designed for His Majesty the Worm! It contains: A GM map and a player-facing map A 30-room dungeon A complete Meatgrinder for the dungeon An alien-clown dungeon lord, the Clown Queen A procedure for making a hub, stocked with vendors and merchants, if the players successfully cleanse the evil

The Sunless Estate is a 24-room megadungeon level for use with HIS MAJESTY THE WORM, a roleplaying game by Josh McCrowell. Designed to be easily slotted in to your own megadungeon, or played as a one-off adventure. The Sunless Estate was once the prime locale for the upper class of society looking to flaunt their status. Wealthy young bachelors would wow suitors with the sights, visiting diplomats would be brought to properly appreciate the prosperity of the kingdom. Beautiful feast halls, libraries, and rolling gardens defined the Estate, all nourished by the Sun Tree, a tree of such size and life that it gave off its own light. No-one in the modern day is quite sure how the Estate fell, or which kingdom or society it was once a part of. They’ve found no skeletons, no remains, no evidence of any life beyond the simple assumption that because it exists, someone must have created it. Now, the feast hall is shattered, the library is burned, the gardens are trampled, and the Sun Tree is the closest a thing can be to dead without quite crossing the threshold. Though the exact amount of time since the fall of the Estate is unknown, it has clearly been enough for the location to find new tenants. The fraction of the Estate that’s been discovered is home to all manner of creepies and/or crawlies, most of whom are divided into factions desperate for a piece of the luxuries and treasure that still remain, trying to squeak out an existence among the many still-present dangers. In other words: an adventurer’s paradise.
