The Thinkers have taken bodies, which have imprisoned them. Though they manage to live peacefully, they struggle to regain their former abilities. When Shinga fails to progress as much as those around her, Avorlig, a Hawk member of the council, seeks her banishment. He seeks Ashyina's help to test Shinga's thought. When their plan goes awry, it leads to the first war amongst their kind.
As the Thinkers struggle to regain peace, people begin to go missing. When Kiran, a Cat member of the council, is visited by an angel named Tryailla, he learns that there are beings much more powerful than the Thinkers. They do not like those who have intruded upon their universe and plan to destroy any who cannot serve them.
