Fey Ravens are an uncommon avian species who are essentially the flying equivalent of Ravens. Though they have the body shape and size of large hawks, their beaks are shorter and wider, more like that of an owl, and their wings appear hybridised between bird and bat wings. Oddly, their call sounds like a kettle coming to the boil, a low whistle that increases in volume and pitch over a few seconds before abruptly stopping. They are normally two colours, one always bright and the other dark, but exact colours vary.
They are not particularly territorial, but are ferociously protective of their nests, repeatedly attacking any creature that comes near enough to be perceivable as a threat to their chicks. When fighting, they most commonly dive directly at their target before teleporting to regain altitude. They make great, if only temporary companions, willing to deliver short-range messages or watch over an area near where they nest, in exchange for food or trinkets to decorate their nest with.
