Correct. The Fallen Leaf is open to other races as well, as I don’t believe running a pandaren only guild to be feasible after MoP as the pandaren race has passed the flavour of the month period and the player base has dwindled.
The Leaf’s focus, theme and goals are all focused on Pandaria and its defense, however, and that’s also where we spend more or less all of our time unless a storyline requires us to go elsewhere. With 8.3 coming and the Pandaria related content in it, it’s unlikely we’ll be leaving the continent any time soon either.
