Yridian NPCs and ships have been presented earlier, but here is the playable species version. Interestingly, the Yridians were thought to be extinct until the 2360s, but in an alternate timeline a Yridian had shown up on Enterprise (‘Twilight‘ episode), so they can be used in that era if desired. For a 2371 campaign, the timeline should allow for a Yridian to have joined Starfleet.
