That is the continent of Pandaria. It was separated from Kalmindor and the Eastern Kingdoms thousands of years ago during the sundering. It has since been shrouded in mists, hiding it from the wars that echo througout Azeroth. And now, the great heroes of both the Alliance and horde have settled there to explore the new wonderful lore there, but also to conqer it before it falls into the wrong hands!
It is known as 'Zandalari Isle' or the 'Isle of Reckoning'.
It belongs to the trolls, and shall be the 5.2 raid.
It has the trolls resurrecting the Thunder King, who was the first Mogu Emperor, I believe.
We stopped searching for monsters under our beds when we realized that they were inside us.
Tell me something, my friend. You ever dance with the devil in the pale moonlight?
