Arwen vs. Galadriel

[Galin]

On an aside, I'm sorry, but how on Valinor can Maeglin be a 'Dark Elf'. The text says "he was kinsman of Thingol of Doriath!" And bangs on, several times, about Eol being proudly Telerin, cross, bothered and spitting chips about all the Noldor-ish Elfy things ruining his Telerin party. Though, he has dark hair! Ha? Telerin, and all that!

Do you mean Eol, or Maeglin? If Eol he was not only a Dark-elf as in 'one of those who had not experienced the light of Valinor' but I think he was called the Dark Elf because he desired the deep shadow of the forest, loving the night and the twilight.

He was called Sun-shy at one point in the tale.

Other dark associations that might be made: it was said that Eol would go abroad clad, in some measure, in galvorn (black and shining like jet) for example.

Melian also referred to the dark heart of the Smith when describing one of his works.
