I would like to contribute to this with an idea of my own

I love creating story lines.
During the birth of the Lich King much of Azeroth was in total war and chaos. Blood and hatred spilled across the lands of Azeroth like a plague killing millions of innocent people. When the Lich King began practicing this great new powers of commanding the scourge there was a human brigade in the Eastern Kingdoms known as the Chaots. They were the most notorius band of bandits, assassins, and thieves that the world has ever seen.
Capable of even stealing from well fortified Citidels as well as being clever enough at killing more than 4 kings of the past human order dating way back before the beginning of the orc and human war. The Chaot's leader, Baron Xarox Devilouse was the immortal leader who lead this clan for more than 5000 years. He was believed to have made a deal with Sargaras ages ago for disrupting order with the killings of several royal members of the human empire. With the success of his task, he was granted immortaily but it proved quite fatal for him as the years passed by.
He began to become haunted of the dead of which he'd slain so carelessly which threw him into a rage. The baron began killing his own followers without regret almost obliterating the entire clan from existance untill human solders of he imperial army discovered him and captured him. He lives even to this day in an imperial prison for all of eternity.
The baron's madness lead to the death of 150000 clansmen obliterating 9/10th of the whole clan from existance. Now as war continues on and death and terror beckons and stirs, Samutome Azeromin, a charismatic and prestigious survivor of the baron's fury decided to revive the chaots. Gathering the rest of the survivors who agreed to revive the clan he begins in a quest to revive the clan.
If he is to accomplish this though, he must do several things. He must first get the full devotion and loyalty of human criminals by first killing a member of the royal family and to attract the attention of criminals in hiding to join the band. The second objective is to go into the hearts of the imperial prison to rescue all captives in return of full loyalty to the clan. The rescue though will not allow for the rescuing of the baron as his fury could sparkle again resulting in the same genocide ages ago. The final step of clan reincarnation is to travel to the elven city of Quel' thalas to rescue all captives there. The greatest madman are captive in the area so the addition of such brutes would prove devestating to enemies of the Chaots.
If these criteria are accomplished, global conquest can begin. The steps would involve stoping an orc assult on human forces to first gain their trust in allying with the clan as well as fighting a naval war in the Maelstorm to get access to the Port of Femtrum. This is otherwise known as the empire of criminals housing the famous black market. With the humans as allies they can provide ships to advance and besiege the port. This would allow all criminals in Azeroth to become loyal to the Chaots enacting phase 2 of global conquest.......
Phase 2 is a continuation campaign to continue what will happen next with global conquest.
