Sylphs are humans whose family trees include elemental beings of air, such as djinn. They tend to be pale and thin to the point of appearing delicate, though their skinny bodies are more resilient than they look. While many can pass unnoticed through crowds of humans, sylphs display their heritage in subtle ways, and those who study them carefully sometimes notice that breezes seem to follow a sylph wherever she goes, even inside rooms with no windows. When consumed by fits of anger or passion, these tendencies become more apparent, as winds surround the sylph and tousle her hair or knock small items from shelves. Many sylphs have complex markings on their pale flesh that resemble tiny swirling designs like blue and gray tattoos, and the most exotic of their kind have hair that twists and coils almost as if it were made of living mist.
