The Devekushu are a species of large bird, native to Karthack but also cultivated in Nisperada, where they were introduced by the exiles who founded the country. They aren't very good mounts, but they're decent pack animals, and they're sometimes used as guard animals to defend cattle and sheep from predators. In Karthack, they are most common in the southern regions, which is where the Nisperadan Exiles came from.
