Shadowlurk

Source: Harker's Guide to Vampire Hunting

If you ever find yourself alone with the eerie feeling of being watched, chances are a shadowlurk is nearby. These sneaky fiends are able to teleport through shadow and are masters of disguise, changing shape at will. Their abilities make them difficult to pin down, which means they make excellent spies. Their abilities are highly sought after by those hungry for information, and as such they are often deployed by fiends, vampires, and other unholy beings.
