Grabrijan is a Vrykolakas vampire Master[1].
Grabrijan is persistently hunted by Arminius Vambrey. He tries to get Amelia to trick Arminius into mistaking Sam Sein for him, but Arminius easily sees through the ploy. This also earns the ire of the elder Vrykolakas Master Philinnon, who had great respect for Lysinda and disapproves of a Lysinda circle vampire being used in such a way.
Philinnon attempts to convert Arminius into a vampire to serve her, but is unable to drink his blood because he has been taking colloidal silver supplements provided by Riff. During his subsequent escape, Arminius burns Grabrijan's face with silver dust from his cufflinks and then stakes him through the heart, destroying him.
