When a Fae produces a child with a human, that child is referred to as a Changeling. There are as many types of Changelings as there are Fae, and each receives unique magical abilities from their Fae parentage. The child of an ogre, for example, will be (in most cases) strong, durable, and none too bright, while the child of a pixie will be hot-headed, clever, and exuberant. Their Fae blood also gives Changelings unique appearances, such as strangely colored hair or eyes. Interestingly, millennia of Fae interbreeding with humans has resulted in some relatively widespread mutations - pink, purple, or even white eyes or hair, along with many other minor abnormalities, are now considered normal amongst humans.
Changelings are heavily discriminated against in Fae culture, and usually are left in the human world. On very rare occasions, however, Changelings are taken in by the Court, to serve as less obvious agents in the human world.
In Camelot, Changelings were shunned and hated, which led to the practice of a Changeling hiding one's status. In the modern day, Changelings have yet to come together as a people, and often live their entire lives isolated from others like themselves.
