Firstly welcome back to RP! Argent Dawn houses a myriad of guilds and I am certain there is one here for you and Yuu 
Secondly I would like to shill my own guild the Havenguard. Simply put we are a Monster Hunter guild that is based in Fallhaven but travels all over Azeroth to combat evil wherever it dwells. At the moment however our storyline is keeping us in Drustvar. If you are interested check us out here! [A-RP] Havenguard - Thros be damned! (Drust/Monster/Spectral Hunters!)
