Born in the late Third Age, Elgarain's mother died in childbirth leaving her to grow up in a male influenced environment, which suited her fine. Dirhaborn was her closest friend; they grew up together and she often spied on him as he learned the ways of a ranger. Her father also taught her about plants and animals, and when her father was killed by Orcs while on a mission with Arathorn she requested to take his place and become a ranger, having often felt more at home in the forest than in village life. Arador was resistant to the idea, because although young women were taught basic woodlore and weapon training, they were usually not fighters. Feeling guilty about her father’s death, Arathorn supported her decision and requested that his father allow him to include her in his team. When Arador reluctantly agreed, he taught her the skills she'd need.
Elgarain was in love with Arathorn, but was devastated when he married Gilraen. Dirhaborn had been hiding his love for her, but finally revealed it when she planned to go far away to flee from her love for Arathorn. When a group of orcs came at them, he told her to run and warn the Dúnedain before the orcs killed him. Elgarain rushed back to Taurdal in time and warned everyone on the oncoming attack. During the ensuing battle, she defended Gilraen and Aragorn from being slaughtered, but was suddenly stabbed in the stomach by one of the orcs that came right up to her. As she lay dying, she apologized to Gilraen for her envy and told Arathorn that he and his son must live and not to lose hope. After that, she died in Arathorn's arms.
