This set of mission briefs (as opposed to mission boxers) takes players of the Star Trek Adventures RPG back to the early days just after the United Federation of Planets was created. As is to be expected from the creation of such a large and diverse group, there's bound to be issues to be ironed out. And that's where your crews come in. You can get your copy of this supplement now.
From the website:
The years immediately following the formation of the United Federation of Planets in 2161 were fraught with challenges for new Starfleet crews, whether they were pushing the boundaries of explored space or developing relationships with the many species that chose to join the newly formed Federation. Former adversaries became allies, and a multitude of species had to learn how to work together.
