While the Expanse was referenced in the interconnected adventures released for the organized play campaign, the first year or so of Star Trek Adventures releases were based on Starfleet divisions (Command, Sciences, Operations) and on the quadrants of the galaxy (Alpha, Beta, Delta, and Gamma). The Star Trek Adventures core rulebook mentioned the region but didn’t go into great detail.


This region wasn’t canonically detailed and was specifically created for development in RPG products. Way back when Star Trek Adventures was ramping up, the organized play campaign that Modiphius started specifically mentioned the Shackleton Expanse, a region of space between the Klingon Empire and the Romulans.
