Mission: The Vault

In The Vault the player is sent to investigate mysterious sensor readings emanating from a derelict Romulan starbase.

Synopsis
Intelligence reports indicate renewed activity at a top-secret Romulan research facility that was thought to be abandoned. The player is ordered to conduct a covert investigation using a shuttle. Immediately on arrival at the Haakona System it becomes clear that the facility is no longer unoccupied. Though the massive station is too large to cloak, there is no telling how large a force is garrisoned there, and so the player finds a way to bypass the sensor grid to enter the station undetected.

Inside, the player finds the sparse remnants of the once mighty Romulan Empire's secret endeavors. The station's still active power and security systems slow the player down as they move deeper into the station, though the Romulan military presence is mysteriously absent. The player encounters some interesting activity, including a salvaged Borg Sphere, but the source of the anomalous sensor readings is found in the final chamber; a massive Thalaron generator.

The player is confronted by a Reman captain identifying himself as Obisek. Obisek explains that a rift has opened in the Romulan Star Empire between the Romulans and Remans since the fall of Praetor Shinzon and the destruction of the Hobus star. He goes on to explain that his resistance movement requires weapons to liberate the Reman people, and that he has no qualms in resorting to barbarism to save his race from subjugation. Obisek suspects the player of acting as a spy on behalf of Empress Sela, and with regret informs the player that he cannot allow anyone to interfere with his agenda.

The player's shuttle is attacked by several wings of Reman Scorpion Fighters, as well as some larger vessels from Obisek's fleet as it escapes. On leaving the Vault the player finds that the cavalry has already been dispatched to deal with the Reman vessels in the system. Due to the environmental effects of the micro-nebula surrounding the Vault, the allied captain asks the player's help in fending off fighters and heavy torpedoes.

The allied ship retreats at high warp to draw the Remans away to allow the player's shuttle to escape. The whereabouts of Obisek or the Reman resistance are left unknown, and the stage is set for what could descend into civil war within the Empire.

Feature Episode Notes

 * First of five missions plus an epilogue mission, of the third Feature Episode Cloaked Intentions released in February 2011. The missions were included at the end of the Federation storyline episode Romulan Mystery, but still form a separate episode (also titled Romulan Mystery) in the Klingon storyline. In the Romulan Republic storyline the episode is called Freedom and contains an additional short prologue mission.
 * The mission is part of the Featured Episode re-runs, and as such eligible for limited time, special mission rewards.
 * 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 per player account and day).

Hints & Tips

 * You can avoid all the sneaking around and just fly your shuttle directly into the Vault. You'll trip security alarms, but nothing prevents you from completing the mission.
 * Failing to enter the interior security codes correctly will lock you out but allow you to talk to some of the station inhabitants (as detected by the Romulan Shuttle). The Romulan Survivor gives you information about the station and a security code override.
 * The player does not need to destroy the Mogai Escort or the Bird-of-Prey in order to escape the Vault. It is advised that the player utilizes the superior speed and maneuverability of the Shuttle (or cloak, if the player is using a KDF or Romulan craft with such capabilities) to evade these larger vessels, rather than trying to fight them one-on-one. If you must fight them, one strategy which works is to stay behind them and use your torpedoes.
 * If you replay this mission to get a replacement Scorpion Fighters device (because you have consumed all of its charges) but are unable to claim it as a mission reward, remember that this is a unique item. Make sure that you don't still have one located in your inventory or bank, equipped on a different ship, etc., and try claiming the reward while aboard your ship. If you are still unable to claim the reward, try moving any other ship device into the device slot where it was equipped then retry. You should then be able to claim the reward. (Source: Reddit)
