My Ghost Feanor story runs alongside canon and is First Age only, it’s… Well, since Anon is interested, here’s the summary:
“…[Fëanor] died; but he had neither burial nor tomb, for so fiery was his spirit that as it sped his body fell to ash, and was borne away like smoke; and his likeness has never again appeared in Arda, neither has his spirit left the halls of Mandos.” What if his spirit has never left the halls of Mandos because it never went there in the first place? Fëanor, dead, watches the First Age unfold, and from time to time, joins in. This story has a beginning, a middle and an end, but is missing a chapter or two in the middle, to cover the period 566-586, from the point where Elrond goes off to join Gil-galad, to the advent of the Winged Dragons. I stopped writing at that point because I was so sad for poor Elrond, Elros, Maglor and Maedhros, so I went away to try to fix things (and ended up writing Feanor does go to Mandos but in the end it’s all OK!). It’s 92,500 words at the moment, and will probably be about 110,000 when complete, which it will be as soon as I’ve got the last chapter of Return to Aman finished off (and have done some actual boring paid work so I can afford to eat while I write :-D ).
