@Hatrag Seeing as launch is still a few days away, for the Sisters of Sylvanas, I’m best found in Discord at the moment via my Discord tag - @Oheowyn/Anoewyn#8960
Or you can pop into the server!
Sisters of Sylvanas Discord: discord.gg/DU7Xv86
I’m also fairly active on the Unofficial Bloodsail Buccaneers Discord server, too - so I’m definitely around! I’ll leave the link below for that too if you’d like 
Looking forward to hearing from you and best of luck in your guild search!
