children. However, he was restrained by the will of the Protector, who was left lying at the bottom of the sea by The Roar. When The Roar returned to the world where Carnac was imprisoned, she was surprised to find him still there. In the Silver City Carnac takes over the minds of the Unearthers so they can literally "unearth" him and lose all sense of their previous personality. Then in the last book is killed by the Protecter and the Unearthers. The Roar The Roar is an enormous creature, an eater of planets. After failing to be able to return to her home planet she is hunting the children of Earth in a last-ditch attempt to resolve her hunger. She has also shut down or eaten some of her body parts. Her newborn have also eaten parts of her, although she later ate them, so only two survive. She often refers to herself as an Assassin. She has found out some of the planet's defensive plans by reading Helen's mind when Helen tried to read hers. The Protector The Protector is the enemy of The Roar. After being shackled to the bottom of the sea for many centuries, a group of children, led by Emily and Freda, manage to free it. When it emerges, it seems helpful and talkative, if somewhat enigmatic, and often visits Helen in her mind, usually to offer advice. Tanni and Parminder Tanni and Parminder are two Unearthers, and digging partners (their drill parts on their hands slot together to become working drills). They start off as nice people, and turn into evil people who only want to free Carnac (who is controlling all of the Unearthers and Thomas's beauty). At the end of the book, when Carnac is removed from their minds, they return to being the people they were before their transformation. They then offer to wait underground for Carnac, and attack him when he escapes from his imprisonment. References Novel series
