Yonadgyrs are an invasive species native to the Tero Canyons. Their soft, earthy camouflage allows them to blend seamlessly with the canyon walls and floor, while their small, nimble bodies enable them to slip through narrow crevices and tiny holes in the rock. As the favored prey of the Drosfolon, Yonadgyrs have evolved to be remarkably quick and agile, with their most notable adaptation being their ability to leap across large gaps between canyon cliffs. Each Yonadgyr sports two pairs of tusks; one set protruding outward from their head, and another curving downward from within the mouth like fangs. It is believed that these tusks help them tear apart smaller prey swiftly, a necessity for a creature that spends much of its life being hunted. Their diet consists mainly of smaller Estalons, occasionally including birds or reptiles. While they rarely stray far from their homeland, sightings of Yonadgyrs crossing into the savannah have been recorded, though these wanderers often perish within weeks of leaving the canyons.
