Hello, and welcome to Argent Dawn.
You can check here to see if any guilds suit what you are looking for or if you need help with a concept you might like to roleplay, I’m more than happy to help out to if you want to contact me ingame.
The [PCU] 
now recruiting! [250] - Argent Dawn - World of Warcraft Forums (blizzard.com)
If not, a gaze around the forums various guilds is an alternative.
Also this… The Blackmoore name in the lore, doesn’t have the best reputation behind it, not sure the surname is something you want to use.
