Worldbuilding Power: Underwater


Use aquatic realms in character development, worldbuilding, and adventures!

When we think of underwater realms, we often think of Atlantis. The fictional island, first mentioned by Plato, sank deep beneath the sea following a series of violent earthquakes. It’s only in relatively modern times that we’ve imagined survivors, adapting to life beneath the seas and rebuilding their civilization. We have Aquaman, Namor the Sub-Mariner, and the eponymous Disney movie to thank for contributing to that lore.

There’s also the Cthulhu Mythos to draw upon. From the Great Old One himself, lying in his house in R’lyeh deep beneath the Pacific ocean, to the Deep Ones residing in the underwater city of Y'ha-nthlei off the coast of Innsmouth, Lovecraft brought horror to aquatic realms. Science fiction has contributed numerous films about modern man living and working under the sea. For humor, we can always fall back on Spongebob Squarepants.

The point is, there’s a lot of material to mine for underwater worldbuilding. Adventurers will find plenty of opportunities to explore, fight strange creatures, and recover lost treasure. Antagonists will pursue those same things, with a more selfish bent. The rest of the world might be oblivious to the existence of the undersea realms, at least until what dwells below comes to up to menace the surface world.

In this book, we’ll show you how to utilize underwater terrain in your worldbuilding endeavors. You’ll see how it can influence character, setting, and story elements. By the end, you’ll understand how to better utilize underwater realms as essential, useful, and entertaining parts of your campaign.

This book is system-agnostic, usable with the fantasy game of your choice. Most of the information, however, is geared toward the familiar tropes and terminology found in “classic” or “legacy” fantasy roleplaying. In the final section we’ll look at how underwater realms might affect the mechanics of the Lighthouse System, the universal story game system published by Dancing Lights Press.

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.
