Malerion. Malekith is a copyrighted name by Marvel. Malekith was created 6 months after the Malekith in Marvel was made. GW smartly changed it to avoid legal trouble. Malerion, so it matches Tyrion. Or if you wanna be a memester, Malekith merged with Seraphon(his dragon) to become Malerion. Annnyway. Yeah. I can't remember which books says that Malerion made his elves look like him due to ego or shit. Might have been Deepkin or the supplement for the death event. Anyway. Tyrion's elves are described as 'angelic beings' iirc so guess angel elves. I assume/hope they look like this.
