- Unroth III
In 2384, Unroth III housed a large Romulan outpost with a vast shuttlebay and medical facility. Romulan doctor D'Mer was stationed at the facility, working with Tal Shiar agent Tovath to attempt to uncover secrets from Starfleet engineer Corey Aster. Special Operations operative Daniel Radke, disguised as Tovath, liberated Aster from the outpost, escaping on a Romulan shuttle, even outrunning two Romulan warbirds in orbit. (Radke's undercover partner, Dr. Alan Melonsky, was killed by three Tal Shiar agents days after they landed on the planet.) (Star Trek: The Cantabrian Expeditions: "Dream a Little Dream of Me")
