I present you a scenario.
The Dark Portal goes from red to purple. A strange humanoid creature enters through, then another, and another until there are armies of them. They are green and sickly looking, but also very powerful looking. They are clad in full body armor and armed to the Teeth. We recognize them....
The Axis of Azeroth:
King Wyrnn leads the charge followed by Genn Greymane, Galen Trollbane, Lord Perenolde, Admiral Proudmoore, Anasterian Sunstrider and King Terenas Menethil II. There mighty generals follow suit as well as a prophet who led them to this path of fel power!
Azoerth of the WOD time line was met by the Legion instead of the Orc whom Garrosh prevented from fully joining with the Legion (only Guldan and his followers joined). It took the Prophet Medivh convincing his childhood friends (now generals and kings) to see that a united Azeroth could conquer not just the world they knew, but worlds beyond. The Human Kingdoms as well as the High elves agreed to this. The Dwarves of the Dark Iron clan also agreed and wiped out the other clans who decided to go against the Legion. The Gnomes reluctantly followed suit.
In a short time All of the Eastern Kingdoms was under the rule of the Axis. Kalimador was selected by Kil'jeaden and Archimonde as the next target for the Axis to conqueror. The Night Elves prayed to Elune and escaped Azeroth. The Trolls, Tauren, and Goblins enslaved and experimented on with foul fel magic!
The Night Elves led by Elune were transported to Draenor where they will assist in defeating the Axis of Azeroth. Can we stop the Fel Armies of Azeroth?
