When I told my friend that Orcs are Elves, he didn't believe me.
So I said due to their real name, Orsimer, ending with "mer", they must be Elves. He dismissed that.
Then, I told him about how Orcs used to be High Elves, but were changed into Orcs when the Divine they were worshiping was "eaten" by Beothia and was turned into Malacath. He then said than in that case, they USED to be Elves.
Afterwards, I began to question my reasoning. Are Orcs indeed Elves?
