Myah tells Noah the truth. She and her brothers stole the precious Thunderstone Cube from the Silver City. As punishment they were banished through time forever. But they secretly rigged the banishment program so it would send them to the very same place and time as the Thunderstone Cube — Haven. Noah realises he’s been tricked into furthering the Family’s evil master plan. The Beast is now a super weapon, able to rain down destruction anywhere, starting with the Silver City. And since Rorden cant work it, they’ll take Noah, by force.

The disintegration of North Col is now obvious. Syndia proposes evacuation but Becky and her parents know nobody can survive in the snow. Maybe Noah will have a solution…

The Nomads besiege the Beast and after a struggle recapture it. Becky arrives in the middle of the fight to tell Noah of North Col’s plight. With the Nomads safely inside, he whites the Beast out, leaving Myah frustrated.

Noah and the Nomads arrive to witness the total collapse of the Mall and the destruction of the holodeck. On the snowfields above, Noah angles the Beast’s beam downwards and the whole colony is sent back to the safely of two weeks prior. Now Noah and the Nomads must deal with Haven. But as they leave North Col, Myah and the Brothers white in. Myah tells Becky and her parents that if they want to see Noah alive again, they must accompany her back to Haven.

Back at the Compound, Noah and Arushka contemplate the Cube under a full moon. The prismatic affect the Cube has in combination with the moonlight reveals some astonishing secrets to Noah. Thunderstone has the property of annihilating itself! If he took the Beast back to the year of the Nemesis Comet, he could use the beam to disintegrate it. There would never be an impact… Noah could create a new future!
