Alyssa in that mythology Berne was a Gnome, a Elf, and Luthien a dark-elf an the integral element that Beren was a MAN is missing an he is a product of two Elves and therefore a Elf.
Do you have anything that Tolkien wrote which proves Dior was mortal? (I'm betting you do, which would be nice as I'd like to read it).
Quote: Published Silmarillion
'And this is my [Manwe] decree concerning them: to Eärendil and to Elwing, and to their sons, shall be given leave each to choose freely to which kindred their fates shall be joined, and under which kindred they shall be judged.'"
"Then Eärendil said to Elwing: 'Choose thou, for now I am weary of the world.' And Elwing chose to be judged among the Firstborn Children of Ilúvatar, because of Lúthien; and for her sake Eärendil chose alike...
Quote: Early Quenta Silmarillion; HoME 5
Now all those who have the blood of mortal Men, in whatever part, great or small, are mortal, unless other doom be granted to them; but in this matter the power of doom is given to me."
From these quotes one can see that Dior was mortal. He died in F.A 506 and Earendil comes to Aman in F.A 542 (I think, I do not have T.O.Y with me at the mo.) therfore Dior's fate was already sealed and Manwe's decree meant that all Peredhil descended from Earendil and Elwing could choose, implying that Dior, Elured and Elurin couldn't and didn't choose and this problem hadn't before occureed-no MORTAL had ever set foot on Aman and Dior was mortal since he was a descendant of two mortals.
And had Dior been classified as a mortal non-elf, I don't think he could have been labeled as "Thingol's Heir" in the Silmarillion Genealogy Tree II - The descendants of Olwë and Elwë
That was the title that he 'labelled' himself with, after Doriath was sacked, since it is true he WAS Thingol's heir, and it was a position of utmost 'respect' and it has little do with his mortality/immortality.
I am the first of the Peredhil (Half-Elven) but I am also heir of King Elwe, the Eluchil
Also from the same essay:
But it was told in the legend of Beren and Luthien that Luthien learned Beren's native tongue during their long journeys together and ever after used it in their speech together. Not long before they came at last back to the borders of Doriath he asked her why she did so, since her own tongue was richer and more beautiful. Then she became silent and her eyes seemed to look far away before she answered: 'Why? Because I must forsake thee, or else forsake my own people and become one of the children of Men. Since I will never forsake thee, I must learn the speech of thy kin, and mine.'
Note she was of the 'children of men' (As she says so herself he is mortal, a man, a hot man at that, or hot woman) and therefore is no mortal and this passage strongly implies she is a mortal man now. (Both quotes from the Problem of Ros, HoME 11
As I already told above, it would be absolutely shocking for me to discover that Dior was a mortal! He was reared among the Elves, he married an Elf maiden, he was then the King of Elves in Doriath... To be counted among the mortals would mean for him eternal separation not only with his wife, but also with almost all friends and companions of his life!
As Aule said err..Asterix's happen
