So my guild is recruiting and looking for Sunwalkers too. We are also more than happy to help out with characters, lore, and Rp if you would like.
I have also seen the Palehorn Tribe around. I have Rped with their GL on another toon and he was pretty cool.
We also have the Tauren Community; The Lodge! We have one weekly event, two momently, and some other events like diplomatic meetings and seasonal celebrations.
