Floating in the air just in the middle of Times Square in new york was a strange crack in the air that emitted a strange golden light, set as a perimeter around said crack, were countless US Soldiers, Tanks, Attack Helicopters, and jets flying overhead.
Suddenly the crack let out a deeper glow for a second as a figure materialized just next to the crack.
It was a man, or what appeared to be a man.
Pale white skin, glowing blue flames where the eyes should be, a strange crowned helmet, long snow white hair, strange armor with a skull molded onto the belt, and knee guards. In the man's hands was a glowing blue long sword with a skull just between the blade and guard.
Suddenly, dozens more figures started appearing around the crack too. Men and women wearing strange armor with decayed skin and missing flesh. They were undead. And each of them had the same blue flame inside their eyes and mouths...
The Lich King and his army have arrived in a new world.
