The adventure text was written by a neural network (Talk to Transformer) and compiled by a human editor. It is surprisingly usable. The adventure is centered upon the dangerous and thoroughly weird Tomb of the Daughter, the burial place and temple of an ancient Goddess.

People keep asking for "beginner" dungeons. Everyone can name "classic" dungeons - Tomb of Horrors, Barrier Peaks, Ravenloft, etc. - but in order for those adventures to make sense, there needs to be some sort of introduction. It's like all the adventures we have are Bach concertos. People keep writing amazing works of staggering genius, but someone needs to write a book on how to play the piano. I had the same questions, and since I couldn't find anything satisfactory, I decided to write the kind of dungeon I would have loved to find. I wanted to write the best basic OSR dungeon for beginners that I could, and I also wanted to show the design process. If you like this dungeon, please share it, tell people about it, print copies and leave them lying around local game stores, or email this post to friends who have "always wanted to try D&D but don't know where to start". The entire thing is and always will be free.

The ancient world of Harth withers beneath its dying sun…but it’s not dead yet. Welcome to the strange and dangerous city of Carcassay, huddled below the skeleton of a titan rat, sprawling above the ruins of countless dead civilizations. This is where folk come to find wealth, power, revenge, secrets, oblivion… and everything in between. Carcassay is a sandbox city adventure. There are many locations to explore in, around, and under the city. Players can explore any place at any time, and may radically reshape the city’s politics, economy, religions, and physical existence. There are standard dungeons stacked under the city, and GMs are encouraged to keep adding more dungeons… all the way down. Tone. It leans more toward low fantasy or sword-and-sorcery. Most shops look like real shops. Most people look like real people. But strange and horrible things lurk everywhere as soon as you start to scratch the surface. This is my Lankhmar. Carcassay is a vast, bizarre city. It has over 100 locations where you can meet Chaos cultists, Lawful knights, retired adventurers, shopkeepers, brewers, musicians, artists, scientists, hermits, royalty, beggars, doctors, space vampires, eldritch horrors, machine priests, crab colonists, mushroom farmers, mummies, assassins, and diplomats from distant lands… and the moon. And every one of them has goods or services to sell, and a quest (or three) to offer. What sort of quests? Fetch a relic, assassinate a rival, find a relative, steal a soul, implant an agent, cure a disease, stop a riot, solve a murder that hasn’t happened yet, hunt a thief, locate a shrine… the list goes on. And for every Quest, there is a specific Reward: money, weapons, relics, Chaos mutations, exclusive memberships, information, Angelic miracles… the list goes on. This is a place where you can make a lot of money, but also where you can spend that money on interesting goods and services. Factions? We have a few. Seven Chaos cults, five knightly orders, two mercenary companies, four wealthy families, six (seven!) Corpse Lords, foreign diplomats, rival innkeepers, rival tavern owners, plus all the dungeon-delving gangs currently mucking about underground. When you grow weary of all the adventures at ground level, there are three classic dungeons buried under the city to explore. This book contains months (if not years) of campaigning. Enjoy the Chaos.

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.
