T'Rina
T'Rina was a female Vulcan who served as President of Ni'Var during the late 32nd century.

In 3189, T'Rina contacted  upon their arrival at Ni'Var to greet them and inform them that their request to access data collected by SB-19 had been denied, due to its cultural and political sensitivity. She reluctantly acceded to Michael Burnham's subsequent invocation of T'Kal-in-ket and witnessed the proceedings. Though Burnham ultimately withdrew her challenge, T'Rina was swayed by Burnham's honest argument that the Federation could be entrusted to use the SB-19 data for the greater good. She thus had the data delivered to Discovery, and expressed to Captain Saru her receptiveness towards further communication. ()

T'Rina visited Federation Headquarters later that year, as Ni'Var was contemplating rejoining the Federation. ()

In 3190, T'Rina attended a meeting at Federation Headquarters regarding a massive gravitational anomaly that struck  and Deep Space Repair Beta Six. She offered the services of the Ni'Var Science Institute to analyze data on the anomaly. As part of this, she mind melded with Cleveland Booker, helping him to gain a fresh perspective on his final memory of his family. Although they didn't get what they were hoping for from the encounter, the mind meld helped Booker and T'Rina expressed her sympathies for his loss. ()

Despite political hesitancy on Ni'Var, she led the world's reentry into the Federation. It was later revealed that T'Rina herself had secretly alerted the Federation President of her people's wishes for an exit clause, leading to Burnham being brought along in Admiral Vance's place in an effort to help come up with a solution. After the successful negotiations, she had tea with Captain Saru. ()

She later participated in the Multilateral DMA Strategy Assembly, supporting the attempt to make first contact with Species 10-C. ()

Captain Saru contacted her to perform a thresh-tor kashek meditation. ()

When the Ni'Var delegate could not arrive in time, she joined Discovery on their attempt to learn more and make first contact with Species 10-C herself. During the mission, T'Rina grew closer to Saru. At one point, T'Ring mind melded with Species 10-C which had negative physical effects on her, but gave the crew more insight into the situation and the 10-C themselves. T'Rina joined the rest of the crew in successfully negotiating with the 10-C to shut down the DMA. ()

Following Discoverys return to Earth, T'Rina and Saru decided to pursue a romantic relationship with each other. She was later present for United Earth's voicing their intent to rejoin the United Federation of Planets. ()
