The Forgotten Abbey is a procedurally generated one-page dungeon that uses a standard 52 card deck.

Explore the crumbling ruins of an ancient temple, now home to a powerful lich who’s unholy magics shift the architecture and resurrect trapped souls indefinitely.

In just one page you'll find:

  • 13 Unique Rooms full of treasure and monsters with which to entice your players to explore.
  • 13 Encounters with the undead ghosts and ghouls that haunt these ruins.
  • 13 Magic Items for the lucky and the brave to discover within.
  • A Card Based Dungeon Crawl System that simulates exploration, random encounters, and lets your players push their luck, spending precious time looking for valuable treasure.

This adventure is stat-less and designed to be used with any role playing system, but assumes an OSR (Old School D&D) type game.

Cards pictured are the Dungeon Solitaire: Labyrinth of Souls Tarot Deck.

This dungeon was submitted to the 2019 One Page Dungeon Contest.

I downloaded this game today, set up my cards and even after reading the instructions, I am still unsure of how to fully play
any tutorials you know of would be helpful. 

for example, in Skeletal Habitat, it mentions a d8, but nothing else of it. what do I use it for? then again in Parlor, how do I open that door?
same with many other cards.

this game looks fun to play, and I am looking forwards to playing, but for now,

Thanks for downloading - its great to hear you're keen to run it!

Unfortunately im not aware of any tutorials on how to play. However, as this is an OSR style 1 page dungeon, its intentionally vague on a lot of the details, and gives the GM the freedom to inject their own ideas. 

To answer both your questions for example, firstly I interpret the dice numbers in front of the monsters as a suggested number of them that appear when drawn. So d8 means you could roll a d8 and use that number, or just pick "4 appear". 

The door in the courtyards is am obstacle for the players to overcome. There plenty of ways for them to do so, perhaps you decide a key is on the corpse of one of the skeletal monks, or one of the grave robbers found it. Perhaps the players can pick the lock, or break it down, etc. That kind of a thing.

I hope that helps!
