Ronden Marr Player's Guide

Watermarked PDF

Two hundred years ago, the surface world was burned away in an event known as The Calamity. Several races found refuge in the dwarven kingdom of Mornfaruhm. Things have not gone well for the survivors- riots, starvation, cannibalism, genocide, and more. Alliances have shifted, and new factions rise and fall.

Dwarves, goblins, humans, and others must put aside their animosity to survive and keep the last remaining civilization from imploding.


Q. What is Ronden Marr exactly?
A. Ronden Marr is an underground campaign setting with an emphasis on intrigue and exploration.

Q. Why should I care about it? What makes it interesting?
A. It's a pressure cooker. There are 50,000 people trapped in a single mountain; no other known survivors of the cataclysm that destroyed the surface world. Historic enemies are now trusted allies, and numerous factions vie for power. 

Q. What system is it for?
A. The goal is to keep it system agnostic and release supplements for various systems. The first system will be 5e (barring licensing issues), followed by others as requested.

Q. Where can I get it?
A. It is currently available here at
The main "Player's Guide" was released in July 2015, with others following as they are completed.

Fantastic campaign setting. Lots of ideas for a good GM as well as giving ambiance and history to the PCs. A neat combination super-city + under-dark style setting. Definitely worth the money for the ideas alone. The production values are great too! [...]

Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
