Overseer are ???.
Overseers are large, bipedal creatures with a bird-like appearance. They possess long tails with a feathered end, similar to CoveyClanners, alongside talon-like hands and feet and a beak-like maw. While their beaks possesses hardened, keratin tips, the sides are fleshy and can pull back to expose sharp teeth. Feathers cover their bodies, with longer, decorative feathers sprouting from their heads, alongside long and tufted ears. It's uncommon to see one that isn't draped in cloths and jewelry. They typically stick to the Farlands, but often approach the Clan's borders. They tend to linger close enough that Clan cats find them quite easily.
Overseers are highly powerful and intelligent magical beings. Unlike the Clan cats, they are able to actively manipulate this magic, and possess the ability to see into and fiddle with the magic and even souls of other creatures. This means that they can be tremendously helpful, but frighteningly dangerous as well. Most speak many tongues, granting them the ability to speak to many species. This allows Clan cats to strike deals with Overseers, giving them items in exchange for prosthetics and other enchanted items. As strong as they are, they cannot conjure new magics for these tasks, and the enchantments are tied to the being that requests them. This means that, for a functional enchantment, it would slowly drain the cat's magic and life force.
As Farlands creatures, they were unknown to the Clans before the Voltaics appeared. Most cats have still never seen an Overseer, but they know that they're immensely powerful beings, able to enchant items for a price of their choosing.
