I hate thinking about Princes/Bard and Pages and their aspect. They're supposed to be the opposite of their aspect, or have a deficit of it. How do you know your a Prince/Bard or Page of something, or something else of the other thing?

 A Prince of Heart may Destroy Heart, but they’re still a Heart Player. Going with the Canon Personality Quiz, for example, Heart Players tend to be heavily obsessed with the Self and Identity. A Prince or Bard of Heart will too, regardless of how they interact with their Aspect. Likewise, say, a Prince of Light, may obscure Information, Lie, make others Unlucky or Irrelevant or whatever, but they’re not going to be Void-Leaning, they’re still going to be Light Players, and that’s the biggest thing to have in mind. 

Also why is the Page exactly there? Pages, specifically, don’t lack their Aspect in the slightest- They get it served constantly.
