A question thats been on my mind lately concerns the late Dior, son of Beren and Luthien. My question is thus, was he a Man, or a Half-Elf. Now it seems the answer would be Half-Elf, since Beren is a man, and Luthien is an elf. But wasn't Luthien mortal when she had Dior ? And if this was the case, and he is indeed a man, then why was he the ruler of the Elves of Doriath. I have never heard of any man leading Elves before, so why is his case different ? Surely the Elves would not care much for being lead by a mortal. So, any theories or ideas ?
