I thought that one sounded deceptively easy!

(Unless it's Luthien).
1 Glimmer fractures around a sigh for lethal epesse.
2 Numenorean declares himself a blade.
Tharbad - Heart breaks and loses direction. No good follows here.
4 Dour and doomed standardbearer.
5 Highelven nightingale
6 I host Gail at place with broken spanner.
7 Elder Nan to Celebrimbor at least
Damrod - Sounds like a cursed wand ranging in Ithilien
Without looking at family trees, I'm going to guess that Nerdanel was one of Celebrimbor's grandmothers. And thinking about it, I think he is the son of one of Feanor's sons - Celegorm, I think. Nerdanel is an anagram of Elder Nan - very clever!
