In the plot of "The Search for WondLa," in the planet Orbona (the goddess who granted new children to parents who had become childless), Eva, Muthr, Rovender, and Otto cross the desert to discover the remains of an ancient human city buried under the sands, then Besteel soon arrives and attacks, severely damaging Muthr.
While in the museum she learns that the life forms of this planet (called "Orbona" by its natives) arrived long ago on a dead world that they "reawakened" for their own use.
