Drust, a male Druid is Bec's mentor. Leading Bec McConn, Goll, Bran, Ronan, Connla, Lorcan and Fiachna through an island, he reaches the tunnel in which he attempts to cut off a tunnel that links the island to the realm of Demonata. He is killed by Bec, who slices his throat with her nail; a sacrifice of a Druid or Priestess was required to close the tunnel, but before this Bran throws a knife into his back as he heard that Drust was going to sacrifice and kill Bec.
