Mongoose JTAS

In May 2024 we presented the all-new Mongoose JTAS Bundle featuring the Journal of the Travellers’ Aid Society, the Traveller guide from Mongoose Publishing. The Journal of the Travellers’ Aid Society is your indispensable guide to adventuring in the Third Imperium of Traveller. Each 128-page volume is a treasure trove of information and enhancements, including adventures, new ships, alien creatures from across Charted Space, philosophical musings on the big empires, histories, different takes on familiar equipment, new vehicles, patrons, characters you meet in starports, playable alien races, and more.

This offer launched on May Day, May 1, known to many SFRPG fans as Traveller Day. The cover of the first Traveller boxed set (1977) featured Free Trader Beowulf‘s iconic call – the universal distress call m’aidez! (French “help me”), transliterated as “Mayday.” This JTAS Bundle, along with our Moon Toad Cepheus Engine offer and a revival of the September 2019 Traveller4 Bundle, marked the holiday and the original SFRPG’s continuing influence.

This JTAS Bundle boosted Mongoose Traveller campaigns like a Jump-4 drive. We presented the first twelve volumes of JTAS (2019-2023, retail value $180) as DRM-free .PDF ebooks. In this list, each link goes to the DriveThruRPG product page that lists highlights of that volume.
