Star Trek Online: Legacy of Romulus (2013)

Legacy of Romulus is Star Trek Online's first expansion pack, announced on March 21, 2013. A third playable faction, the Romulan Republic, was added, with the choice of Romulans or Remans (at present) as player characters, as they battle a mysterious new enemy and try to discover the secrets behind the destruction of Romulus two decades earlier. Denise Crosby, who reprised her role of Tasha Yar during STO's third anniversary, reprised her role of Tasha's daughter Sela, the Romulan Empress. Also featured is a complete leveling experience from level 1 to 50 (the current level cap) for the Romulans and for the Klingons, a Tholian reputation faction, a customizable UI, and an overhauled "traits" system.
