On November 10th, 2008, at 9pm Eastern Time... The Lich king attacked orgrimmar.
On this same day, at 9:15 Eastern Time, Garrosh Hellscream challenged Thrall to a dual in the Orgrimmar Arena.
This live footage was caught by our Gnome-On-The-Scene.
As it turns out, the rule of the Arena match was no healing allowed, a true dual... So Thrall did not have the upper hand.
Also, many are saying Thrall let Garrosh win so that Garrosh would have the courage to do what his father failed at, and face the scourge and the lich king. By defeating Thrall, he becomes part of a new faction, the Warsong Offensive, which will take fourth command of the invasion into Northrend on behalf of the citizens of orgrimmar.
Both songs came from the game soundtrack of Red Alert 3, which was in it's special edition package, the 'Premier Edition' of the game..
