Dragonborn

What a curious new oddity they are, the Dragonborn. Back during the First Awakening, Dragons and Humans lived in peace, but things seem to have changed a bit after they came back. The Dragons themselves seem more aloof than usual and worked some kind of ritual soon after their grand return, in the ruins of this city of ours. It has been many years since, and every new year sees more of these Dragonborn and their Kobold fellows flocking to these ruins, rebuilding them to resemble their former glory. It is all the same to me, not being a Human myself, but still I wonder. Sometimes I see Humans and Halflings here but soon enough they're gone and only Dragonborn and Kobolds yet remain. 'Tis strange, I admit. Only conclusion I can reach is that the Dragons' ritual is luring them here and turning them into these Dragon-Human hybrids but to what end?

Breath Weapon: You can use one of the attacks of your attack action to exhale destructive energy. It deals damage in an area according to your ancestry. When you use your breath weapon, all creatures in the area must make a saving throw, the type of which is determined by your ancestry. The DC of this saving throw is 8 + your Constitution modifier + your proficiency bonus. A creature takes 3d6 damage on a failed save, and half as much damage on a successful one. The damage increase to 4d8 at 6th level, 5d10 at 11th, and 6d12 at 16th level. You may use your breath weapon a number of times equal to your Constitution modifier. You regain expended uses on a short or long rest.

Draconic Flight: When you reach lvl 5, you learn to channel the magical energy of your Draconic Ancestry to give yourself temporary flight. As a bonus action, you sprout spectral wings on your back that last for 10 minutes or until you're incapacitated or you retract the wings with a bonus action. During that time you have a flight speed equal to your speed. Your wings appear to be made of the energy of your Breath Weapon. Once you use this trait, you can't use it again until you finish a long rest.
