Lord of the Rings Series -- Amazon

The thing is, they're bathed in Silmaril light every night. (Assuming we buy the ridiculous premise, which is patently anti-canon) Earendil was put up in the sky as a star by the Valar with a Silmaril.
This plot makes as much sense as having Abraham Lincoln show up as a Cthulhu cultist.
Welll.... the star of Earendil was a Silmarilian and put up by the Valar. So, that part is accurate.

Also, the fading of the Eldar was a very real thing. They would diminish amd fade is away from Valinor for too long. They cheated that a bit by making the 3 rings. So, that being a big concern of Gil-Galad is reasonable. Now... mithril? Eh..... interesting.
