Welcome to WoW and to WrA!
If you haven’t yet, check out the WrA Information and Directories thread. There are a bunch of adverts there for guilds, communities, and recurring public events, as well as some tips and links to RP guides.
Reading through the guild recruitment ads might help you pick out a few to approach and, if it’s not made clear in their forum post, ask about their willingness to show a new player the lore ropes.
Good luck on your search!
