Hey Faralë, welcome back to the game 
Going to link you to a reply I wrote for another poster - I hope it gives you some inspiration or direction for what kind of guild you’d fit into.
I think practically every RP guild around here does RP and hosts events 
You’ve got a world of options to choose from, so if you narrow down your search, it’ll be easier for us to point you toward a good match for your play style and preferences.
Practically all RP guilds are happy to take newcomers aboard, too!
Hope this helps.
