- “Seedea System Patrol”: D'naen Trix hails the player and asks them to distract a fleet of Gorn ships while the Rover rescues survivors from the local space stations, which has come under attack. Once the rescue is complete, Trix departs, intending to bring the civilians to Starbase 26.
- Although Spock of the Mirror Universe wore a mustache and goatee, no Romulan in any Star Trek show or film was ever portrayed with a beard. In Star Trek Online, D'nean Trix is the only Romulan with that feature.
