The Cathedral of Eldenfurth

March 17, 2026

Publisher: Dungeon Masters Guild

The Cathedral of Eldenfurth is a 4 hour one-shot for characters of level 1 to 6. It can be adapted to any other experience level.

The ancient wards protecting the city of Eldenfurth are failing. Only the recovery of the Order´s lost Holy Tome can prevent the return of the Demon Lord Malagruun. Can you unravel the cathedral´s ancient riddles and save Eldenfurth from certain doom?

Inside this adventure, you will find:

Intricate riddles: Decipher the mystery of the 12 statues and the ancient tombs within the crypt
Combat: Face off against the undead and those possessed by malevolent forces.
Roleplay: Engage with a cast of NPCs and explore the order´s grounds to uncover the truth.
The Unwanted Gift: Figure out how to "get rid of" a very funny and troublesome tome.
Battlemaps: 3 animated battlemaps of the cathedral, the crypt and the surrounding forest, self-created with Arkenforge. The maps are also provided as .jpg versions. All maps are provided with and without grid.
For users of Arkenforge, I also provide the arkenforge data so you can use it with all arkenforge functions and can also adapt/change the battlemaps.
A word on AI useage: The story, puzzles, characters, and battlemaps are handcrafted. AI was utilized for character and location illustrations to enhance the visual experience (as my time and even more skills are somewhat limited when it comes to drawing pictures), and for initial brainstorming of names (though most were ultimately custom-named).
And allow me a note on Pay-What-you-want: This title is available as PWYW so everyone can enjoy regardless of budget. However, like a lot of other authors, a lot of heart and hours of work went into this adventure. If you/your group enjoyed the adventure, I would be incredible grateful for a small contribution. And even more importandly: Please leave a review if you liked it or put in a comment, so that I know what you enjoyed and what can be improved.
