Galdor (elf of Gondolin)
From Tolkien Gateway
During the First Age, Galdor was a Noldorin Elf, who lived in Gondolin during the First Age, and was the leader of the Folk of the Tree. He was said to be the bravest Elf of Gondolin, save king Turgon himself. After the Fall of Gondolin he fled southwards to the Mouths of Sirion. It is said he later returned to the Undying Lands, and dwelt on Tol Eressëa.
