You will receive the following reward:

In Under the Cover of Night the player is sent to stop T'Par from selling Federation secrets to the Romulans.


When a Starfleet Officer goes missing, the crew must race to a distant world to stop her from giving vital intelligence to the Romulans.


Mission Text[]

Starfleet is facing a critical situation, <rank>. Your assistance is required to resolve it successfully.

T'Par is a Starfleet officer assigned to be an intelligence analyst for the Federation Council. She knows almost all there is to know about Starfleet's plans to defend the core worlds of the Federation.

Starfleet Intelligence has reason to believe T'Par wants to sell that intel to the Romulans.

In fact, we know that T'Par's hid the fact that her father was Romulan when she applied to Starfleet. What else has she concealed?

T'Par is quite resourceful, and she has contacts in the Orion Syndicate. There is a 62.78 percent chance that she will use those contacts to broker a deal with the Romulans in the Agrama system.

Go to the Agrama system, find T'Par and bring her back. Do now allow her to escape.


Head to the Agrama System located in the Sierra Sector of the Alpha Centauri Sector Block. Find and apprehend T'par before she can sell Federation security secrets to the Romulans.

Mission Reward[]

With the release of the Legacy of Romulus expansion on May 21, 2013, all missions originally rewarding a choice out of three profession-specific Kits, now reward a packed up Profession-Specific Mk <> Kit Reward, that automatically scales to the player's level and his chosen profession. (Release Note 2013-05-21)

Mission Replay[]

This mission is repeatable through Mission Replay, although the Rewards for completing might be reduced. Items scale to a player appropriate level (Scaling Rewards), as followed:

Level Rank SP Exp Mark <>
26–29 Commander 1552 1338 VI
30–39 Captain 1743 1878 VIII
40–49 Rear Admiral LH & UH 1935 1856 X
50–60 Admiral 1935 2148 XI


  • The Cargo Stashes look like crates in space. Proximity of about 5 km will allow you to Scan Area.
  • The Freighter might be any of the surrounding blue ships.
  • T'Par replaced Franklin Drake as the rogue operative in this episode around Season 5 or before.
  • The plot of this episode is very similar in concept to the Star Trek: Deep Space Nine episode Inter Arma Enim Silent Leges. An operation designed to let the Romulans think they've won, so they will hold on tightly to bad intel.
  • As always the enemies scale in relation to player rank. There are numerous turrets on the space map, at the Lieutenant Commander rank they are Plasma Turrets, up to powerful Heavy Tricobalt Turrets at the admiral rank. These are located in proximity to the four Cargo Stashes.
