They also came to learn the important lesson that one must protect galaxy Zovereignty at all cost. Earth is a planet of mortality and imbalances and is not a place such as Zovereignty, Galaxy The Great. Calo is from planet Ethenz, is intersex and goes by the pronoun, They. While here, Calo collects souls to take back with them to Zovereignty, and they also get to meet others from their galaxy living on earth.
