Many people do NOT know about the REAL Warcraft. Most only know WOW, but not the RTS Warcraft, the series only having 3 games in it. Humans fought the Ocrs when they came through the Dark Portal. Undead were summoned by Orcs and took their place for half of Warcraft2. Warcraft 3 is about the Orcs needing a new place to live. The Human prince takes a Cursed Sword and turns into the Dark Knight. The Dark Knight then serves the Undead. The Humans go to the Elves to get help against the Undead. In the end, the smart Elves, Humans, and Orcs team up, defend the Tree of Eternity and defeat the Undead once and for all. Though the Rain of Chaos where the Undead summon Flaming rock monsters 20 feet high seemed kinda hard!
