Hello Glindain, and welcome to Argent Dawn!
Dwarves are a fun race, and I myself have switched to a dwarf as my RP main in preparation for The War Within. While I haven’t been in any dwarf guilds, I’ve roleplayed with these folks, and they seem fun:
I second Jeyce’s recommendation for questing through the dwarf zones as a source of lore and race feel. Make sure to do the heritage questline at level 50, too, if you haven’t yet. And I’d be happy to help you with questions about lore and RP if you have them!
