This is an early, work-in-progress, text-only version

CW: death, despair, solitude

Thought space was full of horror? Try being trapped 50 metres underwater. On your own. In the dark.

Thousand Empty Light is a a source book and solo adventure for Mothership RPG (1E) set in an abandoned underwater tunnel on an uninhabited planet. It is funding on Kickstarter between 1st Feb and 15th Feb.

It's a deep-sea survival and cosmic horror experience wrapped in an in-universe corporate document that blurs the line between sci-fi horror source material, Mothership adventure and universal solo toolkit.

Essentially this is an experiment in tabletop adventure design, requiring a healthy amount of interpretation from the player (though the final version will be accompanied by a digital example play document). If you're interested, I have an article discussing my thoughts about solo adventure design.


The version you can view by pressing the 'Run game' button is a very early, text-only one written in markdown that gives you a sense of the adventure. However it is lacking in a lot of things, including visual imagery, proofreading, editing and playtesting. You'll also notice it's only part of the whole thing. This isn't designed to be necessarily playable in this format. Whilst this potentially includes spoilers for the finished product, a lot of the narrative text is likely to change between now and then.

Take a look at the Kickstarter page for more information and to see some cool pictures / listen to some cool music (oh yeah, there's a soundtrack too).

The title of this adventure was provided by Chris Bissette's Random Adventure Title Generator, and is submitted as part of the Random Adventure jam.

Will you be offering late pledge options for the kickstarter? I love this project so far but missed the funding.
