Flayt are a sentient species of anthropomorphic animal, similar to harpies or tengu. Their intelligence is equal and like unto that of a human.
General Physiology:
Flayt are covered in white feathers and are the only humanoid species known to have a wyvern body plan, with two razor-edged wings and two strong legs. Their heads are round and come to a point, like a bullet, and have a dorsal crest like a pterodactyl that tapers into a spike. As for the rest of them, they demonstrate a large chest, their legs are like that of a harpy eagle's, right down to the plume of feathers around their ankles, and they have a thick tail they use for steering and whacking opponents. (I am unsure how Flayt will manipulate objects, as feet are just not very effective for that, and while Flayt heads are like porpoise heads, I'm not what works for porpoises is feasible for an intelligent avian species.)
General Abilities:
Flayt spend most of their time in the air; like condors, they seek out thermals and glide whenever possible, but they can also stay aloft through sheer endurance, much like swifts do. Despite this frequent flying, their legs are still very much present and very strong, likely because Flayt have no arms to fight, carry objects, or use tools with instead.
Flayt are also known for their destructive shrieks; when riled, they can expel air with enough force to break a man's nose from across a typical room, and the sound generated can and will shatter glass or delicate crystal, as well as break nearby eardrums.
Like most birds, Flayt are tetrachromats and have impeccable eyesight, even over long distances, much like an eagle. Like a harpy eagle, they are also incredibly strong, capable of flying while carrying a lightly armored soldier. Flayt are also capable of speeds akin to a hunting falcon, and can kick like an ostrich. Because of this, Flayt are not commonly messed with.
General Nature:
Flayt are a fierce, proud species, but also somewhat detached. They're often observers, amateur philosophers, and intellectuals-it's not that they don't act, but living up in the sky, with almost nothing to worry about and plenty to watch, with plenty of distance between them and the other Scorayt, leaves one with A) lots of time to think and B) plenty to think about.
Flayt may also struggle with a habit of mimicking other's speech (or sounds they hear around them), repeating themselves, vanity (which tends to go wing-and-wing with frequent preening or plucking), magpie syndrome, singing instead of talking, along with constant pecking and/or eating (the latter of which may go wing-and-wing with Demanding and Devouring Crackers Constantly Disorder, or DDCCD).
The question: How will Flayt fit into a typical medieval fantasy society?
Specifications for Best Answer:
The best answer will account for how involved in society Flayt are likely to be, because that will help determine their role and their level of importance. Given that Flayt spend most of their time in the air, and they'll likely spread out to avoid collisions and conserve resources, I don't see them being especially social....which makes it hard to see how they'd end up interacting with a medieval society. Perhaps they just can't avoid humanity?
The best answer should also account for Flayt abilities when determining what role they will play in a medieval fantasy society, as that tends to be a rather important factor in what jobs a person fulfills IRL.
Clarification-Or, Why Flayt will likely end up in human society:
Flayt are Revelians, one race among many anthropomorphic denizens that lived on Reaville. For quite some time, Flayt only interacted with Viji (another Revelian species), as both species lived on mountains, with the two eventually coming to an uneasy peace. However, then the humans arrived on Reaville, desperate refugees from an oppressive empire, who ended up not only joining the natives but uniting them under one banner and one leader.
Even after the 'Scourge Apocalypse' that destroyed the kingdom and reduced the Revelians to little more than animals, and resulted in the loss of the human population, they still remembered what they once were. Because of this, the second the Flayt end up in Alendyias and realize there are people, they're going to get involved.
Why? Because after they lost the humans, after they were no longer led by a human, everything went wrong. This would strongly imply that for things to get better, they need the humans! And, not sure how important this is, but Flayt and Viji are still allies today.
