louper description

There was a snarl, and then the creature that had been Harley MacFinn came through the doorway. The loup-garou was a wolf, in the same way that a velociraptor is a bird - same basic design, vastly different outcome. It must have been five or five and a half feet tall at the tip of its hunched shoulders. It was wider than a wolf, as though a wolf had been squashed down with an extra five or six hundred pounds of muscle. Its pelt was shaggy, jet-black and matte, except where fresh blood was making it glisten. Its ears were ragged, upright, focused forward. It had a muzzle that was too wide to belong to anything natural, a mouthful of teeth, and MacFinn's blazing eyes done in monochrome grey, the whole stained with blood that looked black beneath the influence of the blending potion. Its limbs were disproportionate, though I couldn't say whether they looked too long or too short - just wrong. Everything about it was wrong, screamed with malice and hate and anger, and it carried a cloak of supernatural power with it that made my teeth hurt and my hair stand on end.
