Ancestral Sin is a diplomacy mission available on Vulcan.

Mission Text[]

We are honored to have a diplomatic delegation from the Romulan Star Empire visiting us, but the ambassador arrived early!

We were not prepared for his arrival at this time, and our available security detail is insufficient for a visitor of his rank.

I believe the presence of a Starfleet officer such as yourself would go a long way toward easing the ambassador's concerns.

If you are able, please meet Ambassador Jirok by the fountain at the bottom of the stairs.


Meet with Ambassador Jirok of the Romulan Star Empire at the fountain on Vulcan.


  • Meet with Ambassador Jirok
  • Convince Jirok to stay
  • Alert Ambassador T'Sawa
  • Gather Evidence and Convince Jirok a Vulcan Didn't Send the Threat
  • Answer Ship Hail
  • Analyze the Notes
  • Confront the Sender
  • Report to Ambassador T'Sawa

  • Ambassador Jirok's visit to Vulcan is referenced later on in the mission “Mine Enemy”.
  • Mission Failure: In the event that a player fails this mission, it is necessary to drop the mission from the Mission Journal and return to T'Sawa on the surface of Vulcan to re-acquire it.
  • The repeatability of this mission has been removed as of July 15th, 2011.
