Dragons of Onyx

Grey is being hunted by the servants of the Onyx Queen. A dark and powerful fey that ensorcelled four black dragons to her bidding, and had sent them in the four cardinal directions to hunt something down. The Onyx Queen was known as the queen of shape shifters, so some of his collegues argue that perhaps these weren't true dragons, but rather powerful fey who had ben granted the ability to take the forms of dragons.
