It is a questing area for level 50+
It is basically a big Island (appears to be roughly 1.5x – 2x the size of Stillmoor) with a volcano in the middle, which I presume is where Maelforge is chilling.
There are two new factions "the farclan" and "watchers". Also about 22 new dailies.
The land is very green an lush and a lot of color in the plants. Also random mobs dropped planar charges for me, and there's also ground spawn clickies that give you a charge as well.
Here are some screenshots I was able to grab
More to come soon
