I just got thinking, after seeing Clamavi De Profundis's Fall of Gil-galad, there's something I found in the last stanza
But long ago he rode away
And where he dwelleth none can say
For in to darkness fell his star
In Mordor where the shadows are.
It struck me last night that the third line may have a different meaning. The name Gil-galad means Star of Radiance, and 'for into darkness fell his star' might not have been his star; it might have been him. He posses no star that I know of, and I think he died in Mordor, I'm not sure. Anyone else have ideas? (I can't believe I didn't notice this before)
