I honestly had no idea
It’s always been there.
The one I never knew about was the one right on the border of Thousand Needles and Feralas tucked away up against on the North wall. Caught me completely by surprise when I first stumbled across it.
Talonbranch Glade has always been one, even before the area got a redesign in Cataclysm to Worgen the place up. I like Classic Felwood better.
We have an FP in Felwood?
Where?
Talonbranch Glade, at the very Northern end of the zone
Island west of Feralas
There’s docks at the mainland and a boat that goes between.
That is Feralas, and the Alliance has two, one on the edge of Thousand Needles - less a quest hub and more just a travel point - and the one you describe, Feathermoon Stronghold, where Alliance characters can learn the top tier of Alchemy.
