Thunderstone

After Drako's raid, Horizon Foundation security orders Noah be confined to his home for his own safety until the crisis is over. Chip finds Clio in the Wildlife Reserve and together with Arushka and Chip, begins to teach Clio about animals. In return, Clio shows them that not all E-Delta kids are bad. While confined to home, Noah searches the files Drako stole in an effort to determine what he came to Earth for. When Drako returns for Clio, Kwan and Arushka (along with Moshi), follow their new friend through the wormhole to E-Delta. Kwan is taken prisoner by Drako while Arushka flees into the hostile wasteland. Apra decrypts the files stolen from the Horizon Foundation, revealing the location of a very special asteroid in orbit around Earth. With a deadly wall of sand approaching, Arushka has no choice but to return to the Bioplex. Drako takes Arushka in but leaves Moshi out in the storm.
