Korvat

Colony where Curzon Dax negotiated with Kang

A colony that was the site of tense Federation–Klingon negotiations decades before Deep Space 9, where Curzon Dax won Kang's respect by walking out in the middle of the Klingon's speech.

Korvat is a colony world remembered in Blood Oath as the place where the Trill diplomat Curzon Dax first dealt with the Klingon commander Kang.
During the talks Kang delivered a long and thunderous address, and Curzon simply got up and left while he was still speaking. The insult was calculated: it showed Kang that the Federation's negotiator could not be intimidated, and the two became lasting friends, to the point that Kang named his first-born son after Dax.
When Kang, Kor and Koloth gather at Deep Space 9 to hunt the Albino, the story of Korvat is recalled as the root of that bond and of the oath Curzon swore with them. The colony is not seen on screen.
