hmm...I think that this could be an interesting concept, except it seems like you are remaking the Lord of the Rings. Elendil was way back with Numenor, Huor was a man in the First Age (The Silmarillion). Sauron is extremely dead. Maybe you could make The Mouth of Sauron be the new villain? He doesn't die in the books, he dies in the movie, so you're all good. And changing the names of the characters along with that would make this story 10x better right off the bat.
Author's Response: You know, I don't know why I didn't see this happening and why I didn't explain myself better but thank you for pointing it out! Elendil is not the same as the one in Numenor, it is a boy that is after the War of the Ring and is given the same name. I feel a fool for not explaining that and perhaps the chosen name was a bit wrong but there is reason to it, I promise. Thank you though so much for the input and bit of aide you offered, it's nice to hear such well versed fans of Tolkien still exist.
