Just an odd thought, but if Harry introduces Fawkes to the Federation adn Starfleet, I can just see a paper on "The Warp-dynmaic Aspects of Phoneix Fire-flash Travel".

Just wait, That is happening in Chapter 15. I want you to imagine the conversation between Fawkes and the Vulcan Head of the scientific division of Starfleet in respects to logic and emotions or the Head of the Chaplains corps regarding mythology and religion.
