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.

The ancient world of Harth withers beneath its dying sun…but it’s not dead yet. High in the night sky, a vampire’s tower is torn apart by a rampaging angel. People and monsters are trapped. Magical treasure lies scattered everywhere. It’s all yours for the taking, if you can find a way out before the angel finds you. This adventure is a one-shot dungeon-delve into a wizard’s tower. In space. With vampires. This is an alien-survival-horror-movie of an adventure (or at least, you can choose to play it that way). ADVENTURE TYPE: One-Shot / Low Level / Level 3 / Dungeon Delve / Tower / Vampires / Survival-Horror DESIGN NOTES This adventure is intended for low-level characters (around level 3). It is focused mostly on exploration, with several social encounters and opportunities for deadly combat. It runs 3 to 5 hours. There are 17 unique magical items, 17 unique monsters, and 17 unique rooms. I swear I did not plan that, it just worked out this way.

Over the years, a large temple to Thuul, god of battle, sprung up around the site. Now, warriors and fighters from across the land travel to Swordfall to pay their respects once in their lifetime. Recently, however, pilgrims have begun going missing. Somewhere between the main road and Swordfall itself, something, or someone, has been waylaying travelers.
