Disclaimer: This is the tale of a land known as Lordaeron and Azeroth, but 500 years after the story of Warcraft 3.Both countries belong to Blizzard Entertainment, but I have borrowed them.
History of Lordaeron after the battle on Mount Hyjal: Lordaeron, the once beautiful country rich with beautiful human cities and castles, is in ruin. The times of old have long passed and the Alliance has been reduced to that of a dream. After the Tree of Life was destroyed, peace and prosperity returned to the besieged kingdom. Arthas, the King of Betrayers as he came to be known, had disappeared to the harsh and frozen world of Northerend. The few undead that had survived after the flee of their master were quickly terminated or chased underground. There was peace for almost a century, until one king rose to power. His name was Farran, Ruler of Lordaeron, and it was by his doing that ended the Alliance and brought Lordaeron down to a mere pile of rubble. Farran was not a very wise king, he lacked the ability of making good judgments, and the fact that he had corrupt advisors did not help the situation as well. For many of his advisors were puppets of the Lich King, Arthas of Northerend. While Arthas had retreated to Northerend, he had put on the armor of the Lich King himself, making him immortal; Arthas was that of the gods; and with this power, he honed his skills, waiting for the right time. There was a demon gate in Lordaeron, closed by the High Elves of Quel'Thalas hundreds of years ago, that held just the army Arthas needed to complete his deeds of death. It was the Gate of Dragons. Arthas attempted to have Farran open it by having undead remnants lure his army towards it, but a sudden attack from the orcs of north Lordaeron changed his plans. The orcs had raised the capital of Lordaeron, with heads on pikes all around. The Army of Farran quickly turned around and headed home. Arthas became enraged with this misfortune and thought. Finally, Arthas unlocked the demon gates of old in the waste lands unleashing the terrible army of the Scourge again to attack the country of Lordaeron. Farran had enough soldiers to counter and even destroy this attack, but he did not, an to this day no one knew why. Instead he led his Army away to the south west, allowing the undead to completely destroy Lordaeron. Farran quickly blamed the unleashing o the undead on the elves, for he had no idea Arthas was still alive, which caused a huge war between the two races that is known as the Great War of Farran. The elves also destroyed most of Lordaeron's southern border causing Lordaeron to be no more than a memory. Because of this, the Army of Farran was cursed to roam Lordaeron until the undead menace was stopped…
The world is corrupted by bickering, killing, and war, each race willing to be dominant. It is in this story I am about to unfold that a strange alliance occurs to defeat a new, greater evil that none has seen before. This evil unlocked by the common foe, the Undead, has begun to spread throughout this Age, the Age of Darkness. The Undead have no idea what they have unleashed; they have started the War of all Wars.....
