Aerin was the daughter of Indor, who was closely related to Húrin Thalion of the House of Hador. When the treacherous Easterlings invaded Hithlum as payment for fighting on Morgoth's side in the Nírnaeth Arnoediad, Aerin was cruelly seized by Brodda. He took her as his wife against her will, hoping to produce an heir to legitimize his rule as Lord of Hithlum. Aerin secretly helped Húrin's wife Morwen and sheltered Sador, the former servant of Húrin and childhood friend of Túrin.
When Túrin returned to Dor-lómin, he learned from Aerin that his mother had left Hithlum. He became angry and in his rage killed Brodda. While being hunted to the death, one of Túrin's followers saw the Hall of Brodda on fire and guessed that Aerin had kindled it. She burned to death in the fire. Afterwards, the remainder of the House of Hador in Dor-lómin were now at risk of being persecuted even more cruelly than they were before.
