Blasted Lands is an area north-east of Stranglethorn Vale, even if they are next to each other the diffrences are great. Blasted Lands is named Blasted Lands for a reason, here the magic was twised and it brought the Dark Portal into being, poping out the rampaging Horde in the Eastern Kingdoms.
Unfortunetly I couldn't take shots of the tainted forest because there were 3-4 hordes at that area and I was too lasy to wait for them to leave.
