Darklighter
Darklighters are the demonic counterparts to Whitelighters, guardian angels in the series. Darklighters are primarily only a threat to whitelighters and witches. They have the task of furthering the spread of evil back to Hades, in part, by luring likely future whitelighters into selfish and evil behavior through seduction. One subgroup of darklighters specializes in furthering the spread of evil by impregnating women and then abandoning them as single parents with their evil far-less-than-innocent babes who will blossom into evil children. This is the counterpart to the Demon Children—the half-human offspring like Belthazor who come about from an upper-level demon's intercourse with a human female, or a demoness bearing a human's child.
