The abandoned Tower of Ulvarum Orvernus stands atop an asteroid nearly a quarter mile in diameter, located roughly 5 million miles from the planet’s surface. The asteroid maintains Earth-like gravity and a breathable atmosphere, with habitable temperatures. This is all sustained through the harnessed power of a bound Air Elemental and Earth Elemental. If either of these Elementals are freed, the asteroid’s environment will quickly become inhospitable. The PCs may find themselves drawn to the asteroid through a forgotten portal, seeking a way to return home. Alternatively, they might be lured there by rumors of a powerful item or hidden knowledge within the tower’s extensive libraries. A multi-level tower filled with traps and strange encounters including animated armor, alien plant life, giant spiders, and a doppelganger.

Under the Temple Crypt is the first in a series of site-based, Swords & Wizardry** compatible, “micro modules” that can be dropped into just about any campaign (especially a sandbox-style campaign). No underlying story-hook or rationale for exploring the site is given here. This dungeon assumes that there is a temple somewhere with a mysterious walled-in doorframe in the basement crypt. The walled-in doorframe predates the temple itself and leads to ancient subterranean structures that hint of an older civilization as well as an expansive underworld.

The Submerged Spire of Sarpedon the Shaper lies to the west of the Isle of the Dismemberer. On the northwestern shore of this island, crumbling steps spill from the shore directly into the sea. There, a seaweed choked stone path can be glimpsed winding down into the depths. At low tide, a quarter mile along the path, a lone onion dome may be seen poking through the waves. In the twilight of the sorcerer lords, The Submerged Spire was the jewel of the Shattered Isles. Within his submarine redoubt, Sarpedon penetrated ever deeper into the organic mysteries. Now, its for- lorn dome the roost of seagulls, its secrets slumber beneath the waves.

Once a paradise at the heart of dwarfdom, the Valley of the Cracked Helm has lain forgotten for ages, lost to the vagaries of natural disasters, goblin invasions, and generational benders.

Valley of the Cracked Helm is an off-beat scenario for old-school style games involving a hidden valley filled with tribal dwarven nudists and exploitative prospectors. It is formatted as a double-sided tri-fold brochure that contains everything needed to run the module. It includes: A ready-to-run module suitable for ongoing campaigns and one-shots. A detailed pointcrawl of the Valley of the Cracked Helm. Dwarves Gone Wild! (This pointcrawl scenario can be dropped into any classic fantasy campaign allowing gratuitous dwarven nudity. More setting than adventure, it encourages/requires referees to improvise or develop content further to fit their own needs. Low-level PCs may need to be lucky or clever to survive.)

Part megadungeon, part underground expedition, Operation Unfathomable serves as both a one-shot adventure and a campaign framework. PCs are (optionally) drafted at swordpoint to recover the Nul Rod, a priceless artifact that was recently lost in a local prince's foolhardy attempt to destroy the Chaos Gods of the Underworld. The PCs have been drafted as an expendable set of pawns to venture into the vast and bewildering Underworld and retrieve the Nul Rod. With the Underworld's innumerable beasties being on high alert after the prince's expedition, the PCs must sneak through the incredibly dangerous Underworld. Fighting is not as important as stealth, fast-talking, and running away rapidly. This is the expansion from Sholtis's original Operation Unfathomable, released in Knockspell #5 (2011).

“Down below, beneath Cassidum’s stinking alleys and crumbling palaces, lie twisting passages and musty chambers with the secrets of the old days, and the subterranean dens of lowlife scum. But now, sordid disappearances haunt the Piazza dei Rospi, while the Literators’ Guild and Barbers’ Guild wage a bloody turf war for the surrounding streets. The key to these mysteries is a richly carved marble well decorated with the carvings of four ugly bullfrogs, whose depths hide things worse still. Some who descend shall win riches and battle-glory, while others will only find horrid death… down in The Well of Frogs!” A 32-page city and dungeon adventure for 1st to 2nd level characters by Istvan Boldog-Bernad, The Well of Frogs describes a neighbourhood of the crumbling city of Cassidum, its teeming alleyways the haunts of thieves and lowlives.

Merchants who have passed through Sacrabad tell tale of how chaos thrives while the good folk wallow in misery. Nim’s guard are no more than a well-paid gang of thugs, hired to enforce his relentless and often bizarre laws and what’s worse, they seem to be in league with a nearby band of goblins, The Yellow Fang, who are often left to terrorize the villagers without reprisal.

The Dark Tower A Worlds Without Number Compatible Adventure The adventure is set up so the Player Characters [PCs] can encounter diverse types of situations and different adventure styles, allowing for role-playing within a rural situation, with wandering monsters, and a dungeon/Deep encounter. The module offers a chance for the GM to immerse themselves and their players with as much, or little, detail as they want to put in. Rolling countryside surrounds The Dark Tower for miles. Giving you, the GM, the opportunity to fit the adventure into almost any setting within your game. I have left the ending open, allowing the GM to slot in further encounters or adventure twists to keep the game moving but with enough happening to turn it into more than one session if so desired. The Plot There are several options for the plot: A local innkeeper would like you to investigate the haunted tower on the hill. He is willing to offer a good reward. A local village Elder could ask the PCs to seek out/investigate/destroy the walking dead that have been seen around the tower. Please investigate the tower to see if the rumors are true. A Local priest would like the PCs to remove the possible undead worrying the locals from the tower.
