Weird story
So Elves were happy in their eternal paradise, then something was blocking their sunlight, and they said:"How dare you?", and they invaded where the cause was from - the middle earth, which is across the ocean, and implemented a thorough genocide.
They were so dedicated, they went to great length to make sure every last one of the orcs was eliminated (on account of not liking sunlight, and being so ugly?).
Anyway the story somehow does not strike me as very innocent.
