Later, when the Toa Metru went to the Coliseum to announce their presence, Makuta, disguised as Turaga Dume, ordered them taken into custody. Three of them, Nuju, Onewa, and Whenua, were swept up in a windstorm and put in Lhikan's cell by the Vahki. While there, Lhikan, without revealing his identity, helped them discover their mask powers. They then escaped thanks to Nuju's Mask of Telekinesis, and found themselves on an island in the middle of a vast plain of sand in a huge cavern. As they attempted to cross the sand, they were attacked by a massive Troller. However, Onewa quickly subdued it with his Mask of Mind Control, and made it carry them safely across the sand.
