In Twilight's case, it's the fact that the Lycalo species as a whole are beings of darkness created through a dude with a funny name that I forgot's magic. As all lycalos are dark creatures, they're able to use that in the form of umbrakinesis.

Or something. Feel free to correct me if I'm wrong, bro. .3.
