Author's Note: No, I do not own any part of Warcraft, whether it is Warcraft 1,2, or 3. This is my version of Warcraft 3: Reign of Chaos (note: this is written before the game has come out, I am getting all information from blizzard's beta version guide, so if this information becomes inaccurate when the real game comes out, forgive me!)
It has been 23 years since the Orcs invaded the land of Azeroth. A new horde has arisen from the ashes, and has settled in Khaz Modan. The nation of Azeroth has been re-established, and constantly pushes the bickering alliance nations to invade Khaz Modan and destroy the new horde. To the far north west of the Azerothean Continent and all its troubles is the Northrend Continent. There lies the growing army of the mighty Undead Scourge, lead by the Lich King Ner'zhul. The demonic Burning Legion is preparing for its final invasion and draining of all magic from Azeroth, and their undead servants are to lead this war. To the south west of Northrend and directly west of Khaz Modan lies the fabled land of Kalimdor, where the ancient Night Elves live and prosper.
The Scourge Army prepares itself for a massive invasion into both Azeroth and Kalimdor to insure victory. Ner'Zhul has hired 4 fleets Goblin Zeppelins to carry a main strike force toward the southern shores of Azeroth, and begin an invasion from the swamps of sorrow.
The Night Elves are aware that the Burning Legion has returned with its new undead army, and they prepare themselves in defense of any invasion attempted by these abominations. Neither the Orcs nor the Humans are aware of the Burning Legion's imminent invasion. Tensions between all four races are extremely high, and a war of titanic proportions is rearing over the horizon. The victor of the war is unclear, but it is sure that the face of the world will be changed forever…..
