Saangi and Alder join Bobby and Loor. As the Rokador prepare to flood the underground, the protagonists foil their plans by flooding it prematurely, presumably to the ruin of both tribes. Rather than abandon one another, warriors of both tribes co-operate to escape the flood. The heroes escape from the floods by riding a "dygo", the machine that the Rokador use for making tunnels. All the water shoots out from the underground and creates a river which flows by the city of Xhaxhu, providing water for both people.
