Merken i'Rateg tr'Vreenak, nee tr'Ortikant, was a prominent Romulan political figure of the 24th century. (DS9: "In the Pale Moonlight"; TLE novel: Serpents Among the Ruins; Bait and Switch: "Flaihhsam s'Spahkh", "Heis'he Ri'nanovai")
- The character is identified only as "Vreenak" in "In the Pale Moonlight". The first name "Merken" is given in Serpents Among the Ruins, while the "i'Rateg" locative and the conversion of his name to Rihannsu styling originates in "Flaihhsam s'Spahkh".
Merken tr'Ortikant had entered public service by 2311, serving as an aide to the Romulan political delegation that negotiated the Treaty of Algeron with the Federation. (TLE novel: Serpents Among the Ruins)
Iliana t'Thavrau worked as tr'Vreenak's chief of staff for nine years in the 2340s and '50s, during his time as governor of Novok. At some point the two began an adulterous affair, which resulted in t'Thavrau becoming pregnant with his child. After this they ended the affair and kept their daughter Morgaiah t'Thavrau's paternity secret to avoid a scandal or a blood feud between the House-clans of Vreenak, Ortikant, and Thavrau, though tr'Vreenak regretted seeing Iliana leave. (Bait and Switch: "Heis'he Ri'nanovai", "Flaihhsam s'Spahkh")
Tr'Vreenak attained a post in the Imperial Senate in 2360 and by 2371 was a leading member of the Jol Tan Coalition and Vice-Chairman of the Tal Shiar. In January of that year he encountered Ambassador Spock and Iliana's daughter Morgaiah t'Thavrau at a special session of the Senate, and informed Spock his party would vote against granting the Federation use of a cloaking device aboard the USS Defiant. Morgaiah and Spock both requested he reconsider, but he refused. Given the parameters of the deal, which included full information exchange with the Romulan Star Empire on the Dominion, Spock regarded this as "an illogical position for the leih of the Tal'Shiar." (DS9: "In the Pale Moonlight"; Bait and Switch: "Flaihhsam s'Spahkh")
Later that year he became the youngest nominee ever for the Praetor Colius Award.
As the Dominion War loomed tr'Vreenak had also become the secretary of the War Plans Council and was one of Praetor Neral tr'Alluera's closest advisors. He negotiated the Empire's non-aggression pact with the Dominion and had little faith in the Federation Alliance's chances.
In 2374 Captain Benjamin Sisko convinced him to detour from a meeting with Weyoun to Deep Space 9 to view what Sisko claimed was evidence that the Dominion was planning to invade Romulan space. Tr'Vreenak and his staff viewed and analyzed the recording and revealed it as a fake, declaring he would expose the plot to the Romulan people. Unfortunately for him, Elim Garak had anticipated this and planted a bomb aboard tr'Vreenak's runabout, killing the senator and his staff and bodyguards. The Romulan investigation placed blame on the Dominion, sparking the Romulans' entry into the war on the side of the Alliance. (DS9: "In the Pale Moonlight")
