War on Nibiru has caused environmental damage resulting in climate disaster. The cities on the surface have moved underground, and a search for the means to restore the climate is beginning. Two brothers have entirely different ideas of how to rule the planet and save the people. Only one of them can be right. Anu wants to use the planet’s resources to further develop the infrastructure of the underground cities, whereas Alalu wants to search for the legendary planet, Tiamat. The legends tell of it having deep veins of gold. If he can find it, the gold can be used to create an atmospheric shield, and life can return to the surface.
