This article contains information that no longer applies to the current version of Star Trek Online. The mission has been removed as part of the Romulan Mystery revamp, released with the 5 Year Anniversary Event on January 29, 2015.

Some parts of this mission have been repurposed in the new mission “Taris”.

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 travelled 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.

The Hobus system has been off-limits to normal traffic since Spock and the Romulan know as Nero were lost there. Even Empress Sela respects the quarantine.

Admiral Janeway conducted the first scientific survey of the Hobus system in 2388. Since then, we've been sending ships out on a regular basis to survey the system and attempt to determine a cause for what happened.

I need you to conduct your own investigation. Perhaps, after all this time, the U.S.S. <shipname> will be the one to solve the mystery.


Survey the Hobus System, which is located in the Devron Sector of the Iota Pavonis Sector Block.

Strategy Notes[]

  • The Hobus System is in the Devron Sector of Iota Pavonis Sector Block.
  • "Moon Patrol": the samples are very well hidden. The Decalithium is in some crates just east of the north conduit, the tekasite is in some canisters some distance north-northeast of the west conduit, and the protomatter is in a blue strip just southeast of the east conduit.
