This jam is now over. It ran from 2022-07-25 22:00:00 to 2022-09-07 22:00:00. View 33 entries

Vaults of Vaarn is a science-fantasy tabletop RPG. It draws inspiration from novels like Dune, Hyperion, The Book of the New Sun, and the graphic novels of Moebius. Vaarn is a surreal and colourful world; a post-apocalyptic, post-human landscape, where the dividing line between flesh and machinery has blurred and the borders between magic, science, and faith have likewise become obscured. For more details on the setting click here. 

The Vaarn Summer Jam is a non-ranked game jam, where entrants are invited to contribute submissions relating to Vaults of Vaarn, and science-fantasy roleplaying games in general. Entries can be adventures, maps, artefacts, NPCs, art packs, or anything else you can dream up. I have a very loose content policy but please don't submit stuff that has no relation whatsoever to science-fantasy.  I would like all entries to be conceptually compatible with Vaults of Vaarn, even if they're not actually written for the setting or system.

All Vaults of Vaarn material presented in the original three zines and on the SRD is covered by a Creative Commons 4.0 Attribution license, and you are free to use it however you want in your submissions to this jam or other projects. The new artwork and adventure locations I produced for the Deluxe Edition are copyright to Games Omnivorous and can't be reused. 

The Jam will run until 31st August. I will endeavour to feature all entries of the Vaults of Vaarn blog when it's over. 

Come join us on the Vaarn discord server to discuss your work in progress.
