Tephrei I was an uninhabited planet, a class I gas supergiant and first planet of the Tephrei star system, located within the Vendor sector and Alpha Centauri sector block of the galaxy's Beta Quadrant. (STO - Romulan Mystery mission: "Tephrei System Patrol")

History and specifications[]

In the 2400s decade, the system was known for its twin worlds Tephrei I and II. Nicknamed "Fire and Ice," Tephrei I was a class I gas supergiant with an average surface temperature of 212 degrees Kelvin and traces of water vapor at the poles. In contrast, the class P planet Tephrei II was almost completely covered with a layer of nitrogen ice, more than three kilometers thick at the equator.

In 2409, Allied starships investigated the Tephrei system for Tkon artifacts. (STO - Romulan Mystery mission: "Tephrei System Patrol")

Sometime later, the Romulan Republic operated a space station in the system. During an Elachi offensive, ships of the Romulan Republic Navy arrived to defend their station against the attackers. (STO - Vengeance mission: "Last Stand")
