Over the wall in Skyfire
 

There is an area of the zone (sw corner near dragon pad) where you can go over the wall. Levitation is not needed to accomplish this, and there are a few mobs up back there. Had to WC hat out last night after my ae pull followed me back there!

Bump on this.

Saw this the other night. Seems like the zone is broken here, it's definitely off the EQ Atlas map and seems to be over the zone wall.
