Yes, and Knight elves would also work, as Tieru was one of them.

Well, I might have exaggerated about the Knights; the elves can be any kind, but they must have a great goal for which it is not shameful to give their lives and wait for eternity + there must be selfish elves - the same "Knights," but without a goal, or rather, those who have decided that nothing is more important than themselves. These are the elves who feel wronged and do everything they were forbidden to do by the "good" elves, or even deliberately sabotage them. They can be compared to Space Marines in Warhammer, but there is one serious difference - the Chaos Space Marines survive by looting, while the dark elves in Heroes have their own cities with an economy, so the faction is led not by Knights, but by Warlocks - an analogue of dark mechs
