The rise of the Tzalekuhl Empire threatens to disrupt the peace that has lasted for generations across the land of Mezo. When the conquest begins, a young girl named Kyma witnesses the death of her father, Hegol, a tribal leader who refused to yield. As the solar eclipse nears, Kyma must unite the various tribes against an emperor determined to make them all kneel before his god or be sacrificed.
Itza’be and Zea arrive at the Tzalekuhl Palace, unaware they are walking into the trap. Emperor Vuh plans to use their piece of the Celestial Seed to cause chaos during the solar eclipse. Meanwhile, at the battle of Cobán Rock, Roden’s loyalty to the empire is tested. Will he help his friends escape with the tribes, or let Phegor hunt down and execute every last one of them?
