A couple of things happened when Caius shifted and used his Noble Authority.
First, Alexia felt the change, as there was a greater concentration of the Shifted Vampire signature, but she wasn't paying close attention to tell who it belonged to. She stabbed her sword through the mouth of one Vampire, and the blade went out of the back of its head after which, she swung the sword and split the head in two.
She cast a spell to repel the two others she was battling and turned her curious eyes toward Caius but he looked as he always did; Beautiful purple eyes and a handsome face with a mouth open to show off perfect teeth that included no fangs.
Caius still had the spark of his lightning spell and the vampire he killed hit the ground and keeled over with a hole burned right through its head. With that vampire's death, the sudden flare of a Shifted-Vampire signature faded away.
