Perris Nodarh was a Heiren male telepath from the Heir'och faction who, in 2251, was to participate in the reconciliation ceremony between his faction and the Heir'tza, following centuries of warfare and hatred.

After arriving in the city of Heir'at on Heir'tzan, Nodarh made his way to the Eastern Temple of the city, and enroute he was kidnapped by six others after his guard was murdered, bundled into a carpet, and taken away from the area in an automobile. Fortunately for Nodarh, Starfleet cadets, James T. Kirk and Gary Mitchell were hot in his trail and followed the automobile by jumping into a manure truck.

Nodarh was taken to an abandoned building at the edge of the city, where Kirk and Mitchell were able to rescue him after engaging in a phaser fire fight with the captors. Eventually, Kirk and Mitchell were able to get Nodarh back to where he was meant to be, and the reconciliation ceremony took place. (TOS - My Brother's Keeper novel: Republic)

In 2265, Perris Nodarh was informed of Mitchell's death, and he in turn informed his attendant, Ataan. (TOS - My Brother's Keeper novel: Enterprise)
