This mission replaced “Taris (original)”. For the NPC, see Taris.

In Taris, the player is sent to the Hobus System to find clues about the destruction of Romulus and Remus, and to discover whether Taris was involved in creating the supernova that destroyed them.


The crew chases down rumors that the former Romulan praetor is still active, and searches for proof that she was responsible for the destruction of the Romulan homeworld.

Mission Text[]

The cause of the supernova that destroyed Romulus remains a mystery. Our allies in the Romulan Republic have a theory on the matter, however.

They believe that Taris, the former Praetor of the Romulan Star Empire, is responsible. Republic forces attempted to apprehend her, but she escaped through an Iconian gateway.

Recently, the Republic has discovered new information that could help us track down Taris. We want you to rendezvous with the R.R.W. Lleiset, the new flagship of the Romulan Republic fleet, and provide any assistance you can.


Travel to the Hobus System, which is located in the Beta Quadrant, and rendezvous with the R.R.W. Lleiset.

  • This mission is part of the revamped Federation episode Romulan Mystery; it was released as part of the 5 Year Anniversary Event on January 29, 2015.
  • It combines elements of the former missions “Ground Zero” and “Taris (original)”, and takes into account the events of “Revelation”.
  • This mission was revamped with new cutscenes on 14 February, 2019. New VO content was also added for Taris for her personal log entry near the end of the mission.
  • When the I.R.W. Sithesh appears, you can actually start firing at it before you answer the hail. If you do this, the Sithesh will not fight back; however, the HP counter will not go down to zero, and will stay at 1. Then, after answering the hail, it skips to the dialogue afterwards, as the ship has already been disabled.
