Deathwing isn't a happy fellow. I mean, how could he be happy with lava seeping through his scales? Zarhym just gave the World of Warcraft community a heads up, because we're about to find out just how pissed off Deathwing is.
In short: we're all going to die. At least once, maybe twice, maybe even sixty times before the event culminates. Deathwing is going to randomly select zones on either the Eastern Kingdoms or Kalimdor, and will fly over them -- laying waste to the land below.
On the bright side, you'll get a cool Feat of Strength for it. You'll also have to pay for some repairs. So, watch out for the sky as it turns black. You may want to try to flee, but you probably won't make it.
One of Azeroth’s oldest adversaries will soon tear through the Elemental Plane to reforge the world in flame, but this foe won’t be conducting his reign of terror from the confines of a castle or lair. Deathwing is a destructive force the likes of which adventurers have yet to see in World of Warcraft, and his appetite for devastation can only be satisfied by the shattering of the world. Following his explosive escape from Deepholm, Deathwing will cast a deadly shadow over the people of Azeroth as he wreaks indiscriminate havoc across the land.
Once free to terrorize the world, Deathwing will randomly choose territories in Azeroth to attack each day until his ruinous reign is brought to an end. A blackened sky will be the only warning before every living creature caught in his approach is consumed by his terrible fire. The unfortunate victims of his malice will receive a rare Feat of Strength... as well as a repair bill and corpse run.
When Deathwing returns, you'd best keep your eyes on the skies.
