Devil Dog

Devil dogs, unsurprisingly, resemble what they are, a small sized breed of Hell Hound, with coal black hairless skin that glistens like polished obsidian, and eyes and maws that burn with the fires of the pit. They understand, but do not speak, Infernal, and their baying cries sound eerily like wailing human voices raised in some dreadful anguished chorus.
