Hey! :D Welcome to the community and such! I'm Iliana! You can always change that Pawn of Princes thing! Go to 'Settings' at the top right, then look for the 'Edit Profile' on the left. It should give you an option to change that thing in the 'Custom User Title' thing.
Annnddd....yeah. If you need something else, let a Staff member, like myself, know! We're here to help you!
