Welcome to Christmas in July! In celebration, this digital title has been marked down by up to 40%! For more of Santa's savings, visit our Christmas in July sale page.

Please note that, in addition to new content, this title includes redesigned and corrected content (in whole or in part) from “When Sea Is Calling (legacy)”. If you already own the old version, you can purchase this bundle to get the new version at a lower cost.


When Sea Is Calling is a system-neutral OSR-oriented guide for (non-historical) nautical adventures. It is intended for both DMs and solo players. With it, explore the surface and the dark depths of the sea, meet its strange inhabitants, lift terrible curses and get your hands on fabulous treasures!

The purpose of this book is not to generate a sea map. Instead, it is meant to be used with a pre-existing one (and is compatible with Sandbox Generator). The aim of this supplement is rather to generate encounters during sea voyages.


This book is in landscape format (11" x 8.5"/27.9cm x 21.6cm) and contains more than 25 illustrations. 

The PDF is bookmarked and a printable version is included.

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.
