In Cold Call the player is invited as a diplomatic representative to the Deferi, but soon finds there is more to the Deferi's request than first meets the eye.


Serving as Ambassador Surah's escort back to Defera, the player notices their first signs that all might not be as it seems; large amounts of wreakage in planetary orbit and a strange ship passing through the system that sensors are unable to indentify. After beaming down to the planet, Surah begins briefing the player on the history of the Deferi, their world, the belief of Balance and the Preservers. The briefing is interrupted when Breen forces beam down to attack the Visitors' Center and the nearby Preserver Ruins. After clearing out the groups attacking the Visitors' Center, the player and their away team head for the Ruins to repel the Breen there, only to be confronted by the leader of the attack. When the leader is defeated, Ambassador Surah contacts the player to inform them that he is returning to his ship. Beaming up, the player must defend Surah's ship from waves of Breen ships.


Mission Text[]

Federation & Romulan Republic allies[]

I was quite impressed with the successful outcome of the recent trade negotiations at Starbase 39-Sierra, and I am pleased to invite the Federation to send an envoy to the Defera system for a more formal meeting.

This could be a great opportunity for both of our peoples. The Federation has requested an alliance with us on several occasions, but my people's adherence to Balance has prevented it. Now they are more open to the idea of ties with other worlds.

Perhaps your visit will be the start of a lasting friendship between our peoples.


Honorable servant of the Empire, I need you to undertake what could be a rather unusual mission.

I understand that diplomacy can be seen as a task unworthy of a warrior in the Klingon Empire, but I sincerely believe that you are the best person for this task.

Your High Council has agree to send a representative to Defera for formal diplomatic discussions. You will be that representative.

We have been friends of the Empire since the time of Emperor Sompek. We were happy to assist his fleet in time of need, and we have been most ... gratified by your loyalty to us over the years since then.

Go to the Defera system. You will be given more instructions there.

And ... thank you. This means more to us than you realize.


Go to the Defera system, which is in the Alpha Quadrant, and assist the Deferi.

Feature Episode Notes[]

  • First of five missions of the first Feature Episode The Breen released in fall 2010. Later retitled Cold War, the missions are currently available for all factions, forming the Breen Invasion storyline episode.
  • The mission is part of the Feature Episode re-runs, and as such eligible for limited time, special mission rewards.
    • For the first Feature Episode Rerun week (May 5–11, 2011) new mission rewards were added to this episode, including making the rewards previously only available through mission replay available for selection on the first run, adding the [Polarized Parabolic Deflector] (a permanent addition to the mission rewards), and adding the choice of level-appropriate badges for the duration of the Rerun week.
    • During the forth Feature Episode re-run (October 31 to December 5, 2013) the mission was eligible for the daily Lobi Crystal reward (once 15 Lobi Crystal icon.png per player account and day).


  • After you complete this mission and you return to sector space you have the option to report to Jiro Sugihara (Fed/ Rom Fed) or S'taass (kling/ rom kling) and if you talk to them after all the breen missions they will have something different to say and you will get an accolade: "The Breen Connection"
  • After completing Cold Call the daily repeatable mission “Aiding the Deferi (Daily)” becomes available from Ambassador Surah.
  • In the initial version of this mission you could obtain a piece of a Preserver star chart by standing in the center circle of the ruins with your captain and ordering your bridge offices or team mates to stand on the corner circles. In a Forum post, Daniel Stahl confirmed, that this piece will be referenced in a later episode. Although you can not obtain it on the social version of the Defera map, you will get an opportunity to retrieve the map in a later mission. Since build ST.5.20100830a.5 the puzzle has been disabled until it is needed for the unfolding story arc.
  • Until the release of Season Five: Call to Arms, the minimum rank requirement for this mission was level 10 and above. The introduction to the Breen Invasion episode was made through the short prequel mission “Aid the Deferi”.
