The Caverns of Steel


*For Middle-High to High level characters*

This place sits on the border between the mundane world and the world of machines. It is a horrendous mishmash of metal mechanical components, contorted and broken and pressed to form this recognizable-but-alien cavern reeking of oil. This is a place where machine life is the norm, and biological meatbags are unwelcome, prone to a toxic demise. Many creatures found here are parodies of biological life, while yet others have discarded all such trappings for a pure mechanical state. Terrible screeches and clanking and whirring of horrible entities echo through these cavernous chambers. In these twisting halls of metal, there are treasures to be plundered, for where metal abounds, there’s sure to be gold.

These caverns are an expansion to the Descent into Madness megadungeon, being attached to ‘First Steps’ on the West and the ‘Vault of Wonders’ on the South. This sprawl has many subsections where various entities have settled in to ply their crafts. Some are more recognizable human imitations. Others are utterly alien. It includes of course many encounters of mechanical nature, a winding treasure hunt with hints that begins in room 59, a town of friendly robots to the east complete with the Robo-Drift DEATH RACE, gateways to other worlds, and more. Despite its mechanical nature, it is still loaded with plenty of magical items and probably too much treasure for the adventurer seeking their fortune!

Hey, did you just forget to list damages for all of the monster attacks in this module, or is their absence some sort of unstated quirk in your homebrew ruleset? The other Five Cataclysms products I've seen include enemy damage ranges.... for an adventure that bills itself as being runnable without prep, this seemed weird to me

Unless otherwise stated, assume 1d6 for damage. The "xtra1Dmg" is just 1d6+1.

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.
