The Sylphlands seems to be the biggest tribe area but I can't seem to find much reason to go there or find much about the lore.

There's a lot of unique places in there and some areas seem very city like. What is the purpose of the Grove area? Why is the Aetheryte in such an arbitrary spot.... couldn't it have been in the Grove?

I haven't admittedlyrics done alot within the tribe quests tgough...
