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.

It will work with any old school games like Old School Essentials or B/X or the most recent version of the world's most popular roleplaying game.

In Claine Forest near Padduck Village there has appeared a pit. No-one knows where it came from, it just did. It is not so deep that you cannot see the bottom, but people fear it and avoid it. No-one who has climbed into it has come back, having been dragged beneath the surface by unseen hands. A necromancer has come to the forest, seeking the pit. She does not quite know what she expects from it, but what she hopes for is protection from death. Player-characters may wish to get involved, and thus this constitutes an adventure for old-school systems, for 5-6 PCs of 2nd level 2 or slightly fewer of 3rd. The PCs won’t necessarily all die, and the players will almost certainly survive. Reviews elsewhere: "It pours out flavour in nearly every word, creating delicious situations for the party to interact with. ... We got a village, two rival groups of adventurers, a weird-ass forest, and somewhere in the forest a pit, your final destination. From this, joy is made. Each one of those elements has their component parts well done and, because of this the whole is a wonder." — Bryce Lynch of tenfootpole

The dead are all mad in this place. Jaume made the most unfortunate mistake of seducing Ysabel and taking her virginity — a sacrilege for which the sentence was death.

Not long afterward, Joudain decided that, because the twin footmen no longer “matched,” he had no choice but to inflict the same fate on Miqèl — who now looks exactly like his older brother. Join them. This heavily revised and greatly expanded deluxe edition of The Cursed Chateau is an adventure for use with Lamentations of the Flame Princess Weird Fantasy Role-Playing and other traditional role-playing games. Death is just the beginning.

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.
