The new patch means new heroics -- and just in case you haven't been wandering around on the 4.3 PTR yourself, we've got a collection of images from all three of the new heroic dungeons. The new heroic dungeons are located in the Caverns of Time as well as the Dragon Soul raid. Two heroics, End Time and Hour of Twilight, are located in a new corridor to the right of the Battle for Mount Hyjal entrance. You'll know you're there when you see all the scenic charred trees and ashes.

If you head down the corridor, End Time is the first entrance on your left; if you head to the end of the corridor, you'll see the entrance to the Dragon Soul raid on your left and the entrance to Hour of Twilight on your right. But what about Well of Eternity? Well, that dungeon has its own entrance -- it's on the other side of the caverns, next to the entrance for the Black Morass instance.

Of course, if you're queuing via the Dungeon Finder or the new Raid Finder tool, you won't need to travel. But if you want to know what you'll see once you're inside, take a peek at the galleries below for screenshots from each zone and the bosses within.
