D.1. Uncursed Human
Mundane humans are the most common sentient species on Earth, and while they are far less prominent in Metamor City than in most other parts of the Empire, they still comprise the single largest component of the population. When lumped together with Plane-touched, who can often pass for human at first glance, and androgynes and pedomorphs, who are essentially "normal" humans with shapeshifting abilities, they comprise nearly half the city's population. Thus, while there are many exotic or supernatural influences on Metamor City culture, the overall "feel" of the city is still largely human.
True mundane humans tend to live in the higher, wealthier levels of Metamor City. This is because most lower-income humans tend to stay away from the city, which can be very dangerous for those without a bit of supernatural talent to help them survive. Those mundanes who do choose to live in Metamor are usually those who are wealthy and powerful enough that they cannot reasonably afford to be away from the center of power in the Empire; such individuals can easily afford to live on the higher levels of the city, where the altitude and inaccessibility are natural barriers to the criminal element (and the increased sunshine is detrimental to most of the monstrous predators who live in the depths of the city).
In Metamor City, those "pureblooded" humans who are not rich or powerful are probably mages, psis, or students attending one of the several universities within the city limits. Metamor City is the best place in the world for higher education, whether magical or mundane, and many who come here do so in order to learn. The Psi Collective also thrives within the city, where the large population allows them to go unnoticed (and provides ample work opportunities for those with their unique talents).
Humans living in Metamor City have to wear special amulets to ward off the Curse of Metamor if they want to keep the bodies they were born with. The wealthy and powerful often wear small technomagical versions that are implanted under the skin; students and other lower-income citizens usually make do with enhanted necklaces, which can be lost or stolen if they aren't careful.
