Well, religion doesn't exist, and organized religion, or cults as we call them, is borderline illegal, with only freedom of thought and speech laws protecting them from jail time. However, a certain group called Taowan (not to be confused with the real life country of Taiwan) are growing as a spiritual type of cult that focuses on personal growth and being at peace with yourself and others. It's an off-shoot of Taoism and Buddhism, but instead of worshiping Buddha or a god, they worship their planet with gratitude and focus on promoting healthy living and a more intelligent population. So I suppose you could call Taowan a pseudo-religion.
King Heidi is part of this group. It's required to be part of it if you are any sort of leader because it shows discipline in oneself.
