Silmarillion: Nerwen. After the kinslaying

I got a lot of questions regarding Galadriels role in kinslaying. It says in Silmarillion that House of Finarfin did´t take part in it. However Unfinished tales, History of Galadriel and Celeborn says: "So it came to pass that when the light of Valinor failed, for ever as the Noldor thought, she joined the rebellion against the Valar who commanded them to stay; and once she had set foot upon that road of exile she would not relent, but rejected the last message of the Valar, and came under the Doom of Mandos. Even after the merciless assault upon the Teleri and the rape of their ships, though she fought fiercely against Fëanor in defence of her mother's kin, she did not turn back. Her pride was unwilling to return, a defeated suppliant for pardon; but now she burned with desire to follow Fëanor with her anger to whatever lands he might come, and to thwart him in all ways that she could.". 

I based my cosplay on this part. It may not be 100% correct for Silmarillion, but I did take an artistic freedom to use the version of Unfinished tales, because I find it very fascinating and inspiring. 
Have a nice day!
