There's a very cool place in Tirisfal Glades right now, found here. It's a forest where there used to be blank space west of the Forsaken starting area. There's a lake with a dead fisherman (his tackle box & chair are still there, as is his back-stabbed skeleton), a forest, and a mysterious mushroom ring in the center of it.
I happened upon it on the PTR, and it's been updated. It's quite possible that it's meant to be part of a quest chain; as it is now, I can't make heads nor tails of it.
Basically, the ring looks like this:
There are, however, several faerie dragons (level 83-85, called Fey-Drunk Darter) flying about. Now and then, they gather and begin to "sing" (musical notes float forth from their bodies, although there's no sound), and the grove turns green, leaves and "energy" flowing upwards:
There are also several brown stags racing through the area, as well as families of brown stag + diseased doe(s) and diseased fawn(s). They're named Tirisfal Stag etc, and are level 80-82, with the fawns at 10-12.
I've also found a new tameable there, but old skin: Tirisfal Bear, level 82 white diseased bear--see post below for screenshot.
Beautiful stuff, eh?
