Arushka, Noah and Sundance notice a curious resonance about the Valley. Even Dolly the sheepdog senses it. Noah discovers that the whole atmosphere is electrically charged. Sundance volunteers to swim and discovers a square blue object at the bottom of the lake! But how can the Nomads move the enormous Thunderstone Cube? Arushka is determined to overcome any obstacle and end the drought. She and Noah use the PH-Ts to travel back to the valley to a time before the lake filled its floor. After all, in the past Noah and Arushka have moved elephants in time, what's to stop them transporting the cube to present day Haven? Noah tunes up the PH-Ts but the cube resists the white light and Noah and Arushka find they haven't moved it at all. Clearly something bigger than the PH-Ts is required. Much of the technology required to create the rain machine is what also enables the PH-Ts. Its all to do with the manipulation of sub-atomic particles of light. If Noah could build the PH-T technology into the Beast, the Protectors' old truck now sitting in the Nomads compound, it could be converted not only into a larger time machine, but also a rain machine. First Noah must travel back to North Col and gather the components he needs. In exchange for access to the rain machine blueprints Myah insists that Rorden accompany Noah. In the Holodeck, Noah enlists Becky's help to keep an eye on Rorden. Noah sneaks down to the storeroom to assemble more equipment. But he is unaware of the dangerous fault in North Col's exhaust line. Noah and Rorden narrowly escape discovery, leaving poor Becky to face the music once again. Back in Haven, Noah contemplate the most difficult task of his life. Can he turn the Beast into an effective time/rain machine, driven by the Cube, or will Arushka's hopes for the animals be dashed forever?
