Autoteleporter up to Ebon Hold. They copied the object across from the other instance [Ebon Hold Starter Maps]
That used to teleport you up to Ebon Hold in the first Death Knight Alpha push. Now you ride skeletal gryphons up. I guess you can see the teleporter in Zombie form, which must be an error with the game. Now it's just for show, on the beta realms.
Many places have DooDad open thingys. AQ gates have one too, wondering if you could open gates twice...
