You really did some amazing worldbuilding there. Beauxbatons truly comes to life as a centre of almost ethereal, otherworldly magic. Xenophilius fits in so well into this strange place. He and Albus make so much sense as allies and friends: Albus as a man who hides behind the facade of eccentricity to conceal a razor-sharp intellect and the burden of guilt, and Xeno whose eccentric facade hides a man who is capable of spotting and voicing fundamental truths about the nature of reality. And I even like Horace in this, to whom I've never warmed in canon. So well done there!
