House of Kamarag
From Star Trek: Theurgy Wiki
One concept the Empire did not have until its encounters with the Romulan Star Empire and later the worlds that would make up the Federation is the notion of an ambassador, one who would speak for the Empire to a foreign power. Prior to that, the only speaking to foreign powers that the Empire did was down the barrel of a disruptor or at the point of a blade. For many turns, the majority of such ambassadors came from the House of Kamarag, starting with Derrax, son of Kamarag, who spoke for the Empire to the Romulans. The last member of the House of Kamarag carried the House name, and negotiated the Khitomer Accords, but the House had many holdings connected to Praxis; that moon’s destruction left the House destitute, and it soon collapsed.
