Aerin

Aerin (aer = ocean) was a woman closely related to Húrin Thalion.

After the Nirnaeth Arnoediad Brodda the Easterling became the lord of Hithlum, and took her as his wife against her will.

She secretly helped Húrin's wife Morwen. When Túrin, son of Húrin, returned to Dor-lómin, he learned from Aerin that his mother had left Hithlum, and in his rage he killed Brodda, thereby also sealing Aerin's fate, who burnt herself alive in her halls, and the remainder of the House of Hador now was persecuted even more cruelly.
