100 Underearth Locations


From now through November 30th, this digital title has been marked down for the Black Friday/Cyber Monday weekend! For more savings, visit our Black Friday/Cyber Monday page.

This is a collection of 100 different locations that can be dropped into an underground journey. The locations are more suited to natural locations than dungeons, but many large dungeons descend low enough that they venture into the underearth realms. Each location is named and described and many of them could have potential adventure and encounter hooks, and some could be dangerous to visit.

Here are some sample results:

  • Lair of the Protean Monster: This region is avoided, for those that travel into it rarely come out in one piece, even assuming they come out at all. The area is filled with tunnels and caves of many different sizes, but no matter where travellers head, whatever lives in the caves seems to be able to get to them, no matter how small the location. No-one seems to have clearly seen it, but the rumour is that it is some sort of amorphous creature that can mould its form to fit through the tiniest crack and come upon people unawares.
  • Lair of the Sublime Humans: A name that has not been accurate in many years for a small cavern complex that was settled by a cult of surface humans who considered themselves to be superior to all others, and segregated themselves to enhance their superiority and purity. Centuries of interbreeding, cannibalism and degeneration has resulted in an almost blind subgroup of feral humans that live in the filthy ruins of the subterranean enclave built by their ancestors.
  • Lord's End: This is a dead-end tunnel in more ways than one, and it terminates at a sheer rock face. Though no sign of it remains, the dead end was the site of a final battle between the forces of an underground lord and his enemies. The lord and his troops were completely destroyed, with not even a monument put up for them, as with the lord dead, his territory was also lost. Today, it is not known who died, or what they were, only that someone met their final destruction at the end of this tunnel.
  • Luminescent Caves: These caves constantly glow with bioluminescence in different colours, and not, if they are examined, because of fungi or other bioluminescent lifeforms inhabiting them. The glow comes from the fabric of the caves themselves, which appears to be alive in some way and generating the glow. The caves are beautiful to look at, but there are rumours that not everything living that enters them leaves again. Some think that the caves entrap, kill and eat some of the visitors.
  • Magma Cavern of the Dinosaur: A cavern that is filled with roiling magma and ranges from dangerously hot to outright lethal for beings that are incapable of surviving extreme heat. Oddly, the cavern does not seem to be connected to any volcanic areas that would provide the magma, and none of the locations around it are similar, leading to a belief that the magma comes from an elemental portal. The dinosaur of the name is a strange creature that lives within the cave. Seemingly formed of magma itself, the creature takes the shape of a dinosaur, and will attack those who enter.

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.
