ermingarden | A belated snippet for Tolkien OC Week

(This is an in-universe footnote from my TRSB fic, in which Halwen plays only a tiny part.)

Halwen the Spearwoman was a Avarin elf who joined the service of Maedhros some time before the Dagor Aglareb. She fought in Maedhros' forces at both the Dagor Bragollach and the Nirnaeth Arnoediad, but it is unclear whether or not she participated in the Fëanorian attack on Doriath. At some point prior to the assault on Sirion she broke ties with the Fëanorians, and she was killed fighting to defend the Havens from her former lord.

A poetic account of the battle, written by a refugee from Sirion, recounts that Maedhros slew her himself:

…In Maedhros' path, upon the sward,
With oaken shaft in steady hand,
Stood Halwen, who had been his guard,
And sworn to fight at his command.

"You are forsworn!" he cried, full wroth,
And drove his sword into her side.
"Better by far to break my oath,"
"Than slay my kin," she said, and died…

But this is otherwise unattested and, as the poet elsewhere takes considerable liberties with historical fact, his account is not dispositive.
