Can't find my other characters to bind into the GT app, any advice?

“Arena of Honor” is our new Competitive Cross-Kingdom Event. This guide shall be handy for all the Royal Lords and Ladies who are getting ready to participate in the event. In this guide, we will briefly introduce what to expect after entering the battlefield, and information about all the Main Buildings sorted by their unlocking sequence. *Please be reminded all the screenshots below are taken from the Test Server. It could be different from the final released version. Once the in-game Registration Phase is completed, the event will enter its Matching Phase, which will take 5 minutes. Then, it will enter the Preparation Phase. Royal Lords and Ladies have 5 minutes to enter the battlefield and deploy their castles, making preparations for the battle. The Battle Phase will last for 55 Minutes. The result of the battle is determined by the Final Score each faction has obtained during the event. Buildings will be unlocked in waves with intervals of 5 minutes. Buildings each have their different First-Hit Point Reward and Points generate rate. Occupying Buildings will take a certain period of time after troops hit the Building, the text “Occupying” will disappear when the status changes.
