Negotiator Sah'Teece is a Rikti diplomat who has been captured by a renegade faction of the Vanguard. He can be found during the mission Accept Gaussian's Mission from Gaussian. He must be rescued from his captors and escorted to the mission exit. He's a mission objective so he must probably survive the mission. No ambushes will come after him once free, though. During the mission he had a faction of Returning Human - Defector (probably an error, nowhere in the mission it's said that he's a converted human), a rank of Boss with the correspondent amount of Hit Points (he will be watered-down if you are soloing the mission at Heroic level) and no attacks at all.
