[Aratlithiel]

Properly speaking, the title High-elves should apply to those two Kindreds of the Eldar who sailed over Sea far back in the First Age to dwell with the Valar. However, in translations from the Red Book, and following the usage of the Dunedain, the term has been primarily used to indicate those of the Noldor (the Second Kindred) who returned to Middle-earth in Exile before the Age was ended.

Either way you look at it, Glorfindel was a High-elf. He was of the Firstborn and had returned to Middle-earth in Exile during the Elder Days. He is featured in many of the Middle-earth tales including the Silmarillion, Unfinished Tales and The Lord of the Rings.
