Wow. A powerful story, indeed, and a scene that I haven't seen done a lot, strangely. Leading into the action, you do a great job with the horror of what Fingolfin saw as he went to face Morgoth.

But without a doubt, this passage was my favorite:

Three times I struggled back to my feet, seven times did I wound him. I wounded him for my brother, for Fëanor. I wounded him for the elves who had perished to keep him at bay over long centuries. I wounded him for the light of the trees that shone no longer. I did not wound him enough. I would have had to cut him a million times to right all the wrongs he had committed.

First of all, I have to applaud you for including Feanor (and not just because I like Feanor). The fanon notion that the two of them hate each other enough to wish death upon the other is one of my fandom pet peeves; I wonder what Fingolfin really thought of Feanor's death. I'd imagine it was a complicated emotion. Secondly, when he says, "I did not wound him enough," I wanted to wubble and cheer at the same time.

Thanks for sharing this! I'm sorry that I missed it when you first posted, but it was a delight to read while catching up. :)
