4000 years ago, the Unpharaoh knew another powerful magician, who built a secret cursed chamber inside the Great Pyramid of Giza. She tells Cainus to lure Bab to that chamber, where not even the Pharaoh’s Beard will protect him.

Bab finds the secret chamber, only to discover it’s the same cursed void that his dad vanished into some years ago. On its spongy walls are hieroglyphs of hundreds of trapped souls. Bab succumbs to the curse and loses his Beard, while at the same time learning a terrible secret about his family.

Can he and the Animal Mummies retrieve the Beard before all of Mumphis is lost?
