The Plainshunters of Lycia

A boundary is formed from three rivers; the Shrike, the Gordin, and the Crooked, all encompassing a triangle of land some 2,000 square miles. This is the Gordin Plains, home of the plainswalkers.
Katorina teaches you how to make a covered fire, so you can roast food and boil tea without being visible for miles around. Her idea of tea is something sweet and overboiled to being akin to a sort of chai molasses, which she assures you keeps for days in a waterskin. You're not sure exactly why you'd want to keep it for days, but you may not wish to be rude.
While you politely drink the concoction (or at least pretend to), she tells you of her people. The Plainshunters are a group of 'natural' werewolves. If a plainshunter has a child with a human(ish) creature, the child will be a werewolf too. Indeed, the Plainshunters don't seem to like each other much, and their preferred mates are those that would seek them out from elsewhere - someone willing to trade the comforts of civilization for the wide open plains. 
Who could blame them? Should you find a Plainshunter who'll have you, you'll have roughly 9 years of company with someone with a rich oral history of stories, myths, and legends as you raise a child and enjoy not paying taxes or wearing pants. Once the child is able to fend for themselves, the parent usually leaves, Plainshunters don't go in for marriage and growing old together. Once the child has reached their early teens, they're usually ready to go off on their own, their heads stuffed with all the tales the parents think will help them through life.
The plains themselves have 4 main creatures; the wolves, the aurochs, the condors, and the rocs. A Plainshunter will use their lupine empathy to lead a pack of wolves to pick off aurochs, using the hunter's superior tactics and strength to allow them to down one of these great beasts. Scattered around the plains are small, naturally occurring salt deposits, and the Plainshunter will use these to preserve the meat to allow her pack to live without hunting for a few days or weeks while they scout out another quarry, or just nap in the sun.
Their diet is supplemented with a kind of small, sweet carrot native to the plains, and other root vegetables that grow from seeds left in the dung of the condors. A small, bitter berry is inedible, but if mixed with sliced carrot, auroch blood, and water then left in a sack in the sun for a few weeks turns into a drinkable alcohol. The bones and pelts from aurochs are treated and sold to travelling merchants in exchange for clothes and weapons. Waterpoof tarps are particularly prized, as they serve many functions and expensive varieties are extremely lightweight.
A Plainshunter has their whole life in a single tent, and will usually pack it into a large cart (or wagon, if the Plainshunter is particularly well-off) and moved around every month or so. Lucky Plainshunters train their wolves to help pull the cart, others may be forced to pull it themselves. Even in the freedom of the plains, no one likes moving day.
Katorina herself is young, perhaps in her late teens or early 20s, although the sun plus the nature of her bloodline makes her appear older. She is unfortunate in that she's mute; while she can speak common very well, she cannot make the snarls and grunts that wolves understand, so she's forced to live by herself. She's usually found in the far west of the plains (where you ran into her) where she can hunt easier pray like thylacines or boars. 
She doesn't seem bothered by this, and explains it means her blood has gotten weak. She cannot transform into her hybrid and animal forms easily, and will never grow as strong as her kin. She will likely not choose to have a child, as the child would be weaker still, and instead will find her own way in the world as a guide. Since she poses no threat to her kin she will attempt to meet with other Plainshunters and learn their stories, as well as co-ordinate between them to establish hunting grounds and boundaries.
Finally she says, when she is old or bored, she will go to the east of the plains, and scale the cliffs there. She will be looking for a Sunstone, a fossilized roc egg that stories say can be found by the most sharp-eyed hunters. Should she fall asleep on it while it is still warm, it will envelop her in yolk, and she will hatch on the first day of spring as a roc herself. Her eyes light up with excitement as she talks about the perils of the cliffs and the true freedom of being the one of the largest birds the valley has ever seen. She says she will change her name to Cassarra, and make her nest high up in the mountains.
You don't know if there's any truth to the legend, but Katorina thinks so. She offers to come on a journey with you for now if you wish, she will need all the strength and wisdom she can get, if she's to find a sunstone.
