Acid Metal Howl


In the deep desert lies the dead city of Yumar, the source of countless bizarre rumors. Was it destroyed by a demonic metal sphere? Did it sink into a pit of acid? Were its people transformed into cursed beasts? Is it ruled by vicious thieves or mad nuns? In fact, the only thing stranger than what happened to Yumar a century ago is what will happen a few days from now...

ADVENTURE TYPE: Medium Sandbox City / Ruin


"It’s laid out and organized well. It’s easy to maneuver through the text and find the information you are looking for. Interactivity is good, there are lots to see and do. A dancing gecko as treasure? Count me in! You can see sites in the distance and trek towards this, this is explicitly mentioned. I love that." --Bryce Lynch (

I really love how your adventure design notes. Very helpful for picking scenarios, especially if one wants to splice them into an ongoing campaign.

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.
