One of the Council of Elders on Organia, who greets the Klingon occupation of 2267 with baffling calm before the Organians reveal themselves as beings of pure energy.
Claymare appears in the first-season episode Errand of Mercy. He sits on the council led by Ayelborne, along with Trefayne, in what looks like a medieval village on a planet lying between the Federation and the Klingon Empire.
When Kirk warns that the Klingons are coming, Claymare and his colleagues decline all help and seem untroubled by the prospect. Their smiling passivity under Kor's rule infuriates Kirk.
In the end the elders show their true nature. Claymare and Ayelborne explain that the Organians developed beyond physical bodies ages ago and find violence painful, and they disable the weapons of both fleets. Claymare was played by Peter Brocco.
