The Thundercaller in port at Tirisfal Glades
The Thundercaller is a zeppelin with a goblin crew and Forsaken guards that runs between Durotar and Tirisfal Glades. A crew was added to the zep with Patch 2.3.0. The crew is constantly making repairs to the craft. According to them, under the command of Sky-Captain Cloudkicker and the control of Navigator Fairweather the zeppelin has crashed repeatedly in a wide array of zones. The undead guards on the Thundercaller simply say "don't ask" when a player speaks to them, possibly hinting that they would still be alive in the traditional sense if they had not signed on with Cloudkicker.
