Gojera

Behemoths, dinosaurs, kaiju—many names are given to the giants that roam on Gojera. Every species in this realm has a threefold metamorphosis through various methods of cocoons or chrysalises. But one species, a humanlike bipedal creature, created societies by enslaving their first and third stages. They hide in castles and villages, hoping the bigger beasts don't find them particularly appetizing.
