Gavan Bayar is the former High Wizard and the main antagonist of the Seven Realms series. He is the head of Aerie House and is father to twins Micah Bayar and Fiona Bayar, as well as Hayden Fire Dancer. When Dancer, Willo, and Han hatched a plan to expose Gavan, Dancer commented he would probably kill all of them. When the three confronted Bayar, Gavan accused Willo of witch craft, and claimed she seduced him. Gavan was killed whislit chasing Han. When Han entered the room full of flesh eating songbirds, Gavan woke the birds, and they sung, and then attacked him, eventually killing him.
