Deathwing's Fall

Deathwing's Fall is located in the lower shelf of Deepholm, southeast of The Blood Trail and Temple of Earth. This is where Deathwing landed when he fell into Deepholm through unknown means after his defeat in Day of the Dragon.

Note
Though it looks like it may be, this is not where the Twilight's Hammer Cult brought Deathwing back to health. The site was in the Stonecore.
