Nightstalker Shadowhounds Regiment

Shadowhounds are huge, black, twin-headed canines, with gnashing jaws and fur matted with vile ectoplasm. Hunting in packs, those lucky enough to escape these beasts can still hear the howling in their heads long after they have awoken. The unfortunate victims who weren't fast enough are devoured, their screaming skulls forever leering from the shadow hounds' foul hides.
