Galadriel

Born in Valinor as a member of the royal houses of the Noldor and kin to the Vanyar through her grandmother, Galadriel was a child of the Elder Days who took part in the rebellion of the Noldor and the subsequent flight from Valinor in the First Age. Across the Second and Third Ages she and her husband Celeborn moved through Lindon, the shores of Lake Nenuial, and Eregion before establishing rule in Lothlórien; at the end of the Third Age she returned to Valinor. (Sources identify her as a royal Elf of the Noldor and the Teleri and place her activity across the First–Third Ages.)

Galadriel is repeatedly described in the sources as exceptionally fair and luminous: called 'the fairest of all the Elves' and epithets such as 'Lady of Light' and 'Lady of the Golden Wood' are applied to her. Tolkien is quoted as describing her as 'the mightiest and fairest of all the Elves that remained in Middle-earth' and the 'greatest of elven women.' (Descriptions in the supplied materials emphasize these honorifics and luminous beauty.)

The supplied sources state that Galadriel could 'peer into the minds of others to judge them fairly' and that she acted as a political and spiritual leader (ruling Lothlórien with Celeborn, participating in the Noldor rebellion, and holding roles across multiple Ages). She 'gave each member a searching look, testing their resolve' when the Fellowship visited Lothlórien; Boromir misread this as temptation. During the Second Age she distrusted Annatar (Sauron in disguise) while the Rings were forged; when Sauron attacked Eregion, Celebrimbor entrusted Galadriel with Nenya, one of the Three Rings of the Elves. She was 'tested' by Frodo's offer of the One Ring and recognized that taking it would make her 'great and terrible.'
