The most numerous species in Nod and the most vulnerable. Humans have no innate magical ability, no natural weapons, no biological advantages beyond adaptability and sheer reproductive tenacity. The only things preventing their extinction are their ingenuity and their numbers. They survive everywhere, including places some of the other species would not willingly go.
Humans are the only sapient species native to Earth. Most arrived in Nod involuntarily, pulled through the Veil by moments of extreme emotion, delivered by strange means such as Cab Seven, or simply lost in the wrong place at the wrong time. The city's lower classes descend largely from people who arrived this way and never found a way home.
Transformation: Nod pries at the deep structures of the human mind, drawing out private fears and hidden desires and giving them physical expression. Horns, claws, fur, living iron bones, steel-plated skin, the ability to survive without breathing. Every transformation is unique. Not every human changes, and there is no reliable way to predict who will or what form it takes. These changes are permanent. Humans who return to Earth carry their alterations with them, though ordinary mortals don't always seem unable to fully register the changes.
