Michel Allard is the father to Thais Allard and Clio Martin, but only raised Thais, in Connecticut. He never knew Clio and never even thought that he had a second daughter. He died in the first book, leaving Thais to be an orphan. He was killed in a car accident and didn't know that Thais was a witch. Thais thinks Daedalus Planchon killed him.
