If you have already thought of a name for your third age character, please update your name to match, Here's how below:
Click on your name in the top right (on mobile there will be a navbutton before your name is displayed) and click Account settings
Change your display name, this will then update on site, Please use the following format "Character name - Town Name" if you don't have a planned tribe name yet, use Eilean Aerin for now and update it later when you join a new town.
If this doesn't update, please contact me and let me know!
Cheers! - M
