Nearly two decades ago, a terrible clash between the warring gods plunged the southern part of the Free Realms under the waves, turning the highest peaks into remote islands and creating the turbulent and dangerous Uncharted Sea.

This cataclysmic transformation destroyed several settlements and brought the coastline up to the city of Spear, a rugged settlement built in the shadow of the colossal Spear of Kabor.

Now, dark creatures from underneath the waves and the sinister will of the warring gods threaten Spear once more. As sailors and locals keep disappearing and the magic storms that surround Spear intensify, most ships have fled the city. Yet a night ago, Captain Kenthor “Rubyeye” Webcrest’s infamous frigate, the Darkstorm, docked at the empty harbor. Captain Rubyeye is looking to recruit sailors, adventurers, and those who seek revenge against the gods to sail into the Uncharted Sea, stop the dangerous magic that threatens Spear… and claim fame and fortune!

Come on, get moving. We sail at dusk!

A huge thanks to all the Catilus Patreon supporters who made this book possible!

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.
