Tar-Telperien was the tenth Ruler of Númenór and the second Ruling Queen. She was a very selfish ruler, who did not relinquish her power until her death. She was asked to intervine in the War of the Elves and Sauron, but she did nothing, instead her nephew Minastir became involved and sent a fleet to Gil-Galad's aid.
She never wed nor had children of her own. When Telperien died, her power and right of succession passed on to her nephew.
