Casting Teleport: Moonglade while in Moonglade will return the Druid back to near their departure point.
Teleport: Moonglade is a druid-only teleport spell learned at level 14. It teleports the caster to the city of Nighthaven, Moonglade. When cast a second time, it sends the druid back to their initial departure point.
Useful for night elfdruids, it allows for a short trip to Rut'theran Village, serving the function of a Hearthstone for their hometown. Not so much for Tauren, since the trip from Moonglade to Thunder Bluff, even if free, takes almost seven minutes. (It used to be a longer ride over Darkshore that took 10 minutes, but now you get the direct way through Felwood). If you have the adjacent flight points, it is best to leave from the non-druid flight-path, close to the bottom of the region, and take the shorter trip to Orgrimmar.
With the ever expanding world in subsequent expansions, this spell became slightly more useful, since it allows instant access to Kalimdor, and from Moonglade easy access to Darnassus and Exodar (via flight path) or Stormwind and Orgrimmar (via flying to Mount Hyjal).
Worgen druids who have not completed their starting zone quests will be given the following message if attempting to use this spell: The fate of Gilneas has not yet been decided. You cannot escape yet.
