Variag

A Tolkien word. Variags are inhabitants of a country called Khand, in southern Middle Earth, between Mordor and Harad. They aren't Haradrim, and nothing really is said about them, which makes one wonder why Tolkien put them in at all. Maybe they were to have some crucial role in a book he never got around to writing? One website says the Variags were very loyal to Sauron whereas the Haradrim were just tricked. At least that makes a bit of sense. In fact I don't think we're even told they're humans. They might be orcs. Or elves. Or aaracokra. AAARRRRGGGHHHH!!!! someone tell me what a Variag is!!!!!!
