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[]

How much do you know about the destruction of Romulus, <rank>?

The initial explosion did not occur in the Romulus System. It was in the Hobus System, which had planets being mined for decalithium.

The supernova acted counter to almost all we know about this type of phenomena. The initial explosion converted the mass of the planets it consumed into energy, which then traveled through subspace. Ultimately, the Romulus System was destroyed, and along with it, the Romulan homeworld.

Unchecked, the force of this chain reaction detonation could have threatened the entire quadrant. It was Ambassador Spock who sealed the rift by using red matter to create an artificial black hole.

Until recently, the cause of the supernova was a mystery. However, the nascent Romulan Republic, our new ally, has shared information with us that Taris, former Praetor of the Romulan Star Empire, may have been responsible for the Hobus supernova. They attempted to apprehend her, but she escaped through an Iconian gateway.

Recently, the Romulan 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.
