There used to be tonsss of them when vulpera first came out. There are still several, but most stick to in game.
Here’s a few guilds you might find interesting: [H] <Waning Crescent Caravan> is Recruiting!
Mystic Paw Caravan
Those are found on the WRA Directory thread here: WrA Information & Directories
I suggest getting in game and looking around for Vulpera RPers, and then seeing what guilds they’re attached to and getting involved with them.
Good luck! If I see anymore guilds I’ll be happy to add them on later,
