Darkness

Doyle is a Unseelie sidhe (fey) character from Laurell K. Hamilton's Merry Gentry series. He was the Queen's Captain for over a thousand years and is referred to as "Darkness" or "the Queen's Darkness" because of some of his magical abilities and the more superficial observation that his skin is black (but not from Africa "black" more like the color of the sky at midnight black).
