Hi Ravenly,
Our guild Braveheart is on Argent Dawn and I think we have what you’re looking for! Our main objectives are to have fun (top priority!), make friends and do a little bit of content along the way - we often spend time chatting and occasionally form groups to do M+ (all newbie friendly and chilled) and some other things, like we do transmog/mount runs often if you’re into collecting.
Check out our recruitment thread is here for more information and if you want to know anything else, send me a whisper in-game (I’m sometimes on alts so may not be on this character but I’m usually online) or add me on battle.net (Hystericxl#2226) or discord (Hystericxl#3376) and we can chat a bit more!
