Moonglade

Use the spell "Teleport: Moonglade" to travel to Moonglade. When you arrive, speak with Dendrite Starblaze in the village of Nighthaven.

All druids are welcomed to the sacred lands of Moonglade. Keeper Remulos--Moonglade's guardian--keeps watch over all druids who hibernate there. I'll teach you the spell that lets you transport yourself there. Cast it whenever you seek Moonglade's knowledge or solace.

As for your first lesson here on Azeroth, travel to Moonglade and speak with Dendrite Starblaze in Nighthaven about the path you're now on. Good luck, young druid.

Ah I see that you have already mastered the form of the Bear. Good, good. You are well on your way, young <class>.
