Iathrim
From Tolkien Gateway
Those Elves of the Sindar that lived in the broad forests of central Beleriand, Neldoreth and Region, under the Kingship of Elu Thingol. These people, whose King had travelled to Valinor in his youth, and whose Queen was of the order of the Maiar, were held to be the highest and noblest of the Grey-elven kindred.
