Were-Avian Nahuals children of Coyolxauhqui and Ilmarinen. They are consider to be the smiths, creators, innovators, messengers and harbingers of news even in some cases as "politicians".
In the same vein as their nahual siblings the Ferronix are called forth by their parents when they suffer a fall from great heights, the Ferronix say and theorize that they were always meant to fall in order to learn to finally learn to fly.
Their auspices are bound to a material they closely affiliated or familiar with rather than the phase of the moon like they closely related Ajabayan and Lobizon siblings. The known auspices are as follow:
- - Quillex - Bearded vulture (or Lammergeier): Also called "Bone Makers" or "Bone Benders" the Quillex are the ones who are closely associated and mainly work with bones as their main material. They mainly create bone charms, fetishes, ceremonial masks, or totems — tying magic to form.
- - Argentax - Magpie: They are the ones who are closely associated with and utilize silver as their main material. They specialize in creating delicate, intricate silverworks like ceremonial swords, mirror-like charms, protective charms that magic and communication.
- - Brambleforge - Kites: the copper workers who specialize in scavenging and repairs, composite formations, and turning scrap into something purposeful.
- - Plumbane - Osprey: The lead workers, they generally work with a more technological and modern approach. If you need guns and ammunition you generally go ask a Plumbane for that.
- - Gildcrest - Thrush-tanager: they are the ones who work with jewelry materials like gemstones and crystals.
- - Aurumreach - Crane: They are the bronze creators and main politicians of the Ferronix, they care more about diplomacy than creating objects.
- - Ravforge - Raven: the weapons smiths that work with Steel.
It is known that the weakness of the Ferronix is Mercury.
