On that note, would they even celebrate birthdays? With their immortality/agelessness, why would one year matter significantly from the next? What kind of culture arose around such people? What differences in their culture exist between their own and humanity's?
Flayn is awesome and I'd love to see her relationship with Mith explored a bit. I mean, I would love to see them interact as a family. Flayn always seemed a little... lonely. You know? I imagine that with a cousin/brother approximately her mental and emotional age, she would be a little livelier. And their species/race/family is so few in number that I think that Flayn and Mith would develop a more sibling-esque bond (as opposed to a more distant, extended family one) by sheer number of interactions.
edit: Mith the size of a continent. Yes. Please make that happen. Dorothea's paling at his... size right now? My sweet summer child. The boy's got some growing to do... and there's arguably nothing more secure (and security is something that she deeply treasures) than the firepower of an ageless dragon the size of a landmass!
