I don't think "rebels" is a good name for an elven faction. I think the name comes from Heir to the Throne but were the elves really rebels? As far as I know the forests inhabited by elves were not part of the kingdom of Wesnoth and elves were not subjects of Asheviere so they could not rebel. They were simply the opposing side of the conflict because Wesnoth attacked the elves, and the elves, through their friendship with Delfador, supported Konrad's resistance.
