The first point was my and that Uroboros's thought as well. Except it had more to do with corrupting Messenger's domain. After all, how would games be if we were all speaking our own native languages rather than the ones we're speaking now? How many wars have been fought over miscommunication? And how can the blanks even think to come up with proper plans to stop the cycle from continuing if they cannot understand each other?
If chaos of that nature were to occur, wouldn't she be the one receiving tribute? Wouldn't she be the one gaining power?
Another thought: considering the Judges who have been killed already, would Queen target the other Judge closely related to Messenger to make him more cooperative? Or even not that, if she is testing the response time of the blanks, couldn't she already have an idea of how things are currently?
... ah, my head's starting to hurt from all of this.
