Today, Scanlon of Book 4 will tell us about fairies. However, at this stage in the novel Scanlon is still inexperienced and his knowledge of magical creatures is lacking. Keep that in mind.
When fairies are developed enough to function outside of their gestational pouches, they weigh between four and ten pounds. When they reach their full size, they weigh between one-hundred and two-hundred pounds. The similarities to human biology end there.
Fairies eat by drawing gases straight from the air; their digestion is extremely efficient, so they are very parsimonious about nourishing themselves. If they live in areas where the air is either thin or heavily polluted, they supplement their diets by eating the occasional flower. Since it takes a huge volume of air to support a fairy, they are sparsely populated, they take around a hundred-ten years to reach their full size, and are accordingly slow to reproduce. They are not technically immortal, but they seem that way to humans because they live such a long time and are vulnerable to so few causes of death.
With their expansive life expectancies and scant numbers, one might think fairies would be wise, steady creatures. In fact, they are widely recognized as the village idiots of the magical world. Fairies are shape shifters who can morph into any form as long as it maintains the same mass. They have nothing to fear from vampires and are in no way dependent on humans, yet they seem to enjoy living in a world that’s densely populated with mortals. They like to play with humans, especially mundanes, in the sense that humans are the fairies’ toys.
