Harthalín is a High Elf and close friend of High Elf player characters. She is first encountered by High Elf characters in the year 3434 as one of the host of the Last Alliance during the siege on the battle plain at Dagorlad at the end of the Second Age.
Other players get introduced to her by Gandalf after the fall of the Black Gate.
