With the expansion only days away, Blizzard has started the Burning Crusade world event that pits the citizens of Azeroth against the foul demonic legion pouring through the Dark Portal. The battle rages on in a number of areas including Stranglethorn Vale, Hinterlands, Winterspring, and Eastern Plaguelands. The patch to the Live servers of World of Warcraft weighs in at a hefty 159MB.

HieroGraphix Game Journal will have more reports about the event later this week.
