The Order of the Child
The Order of the Child is the only known formal religion to worship Ya Su directly. They believe that her power can shape reality as they see fit. Some believe that Ya Su is a messianic savior who can turn any world into a paradise but destroys any world that is unworthy of her paradise. Many worshipers of Ya Su are insane and seek out any way to bring her to their world by getting her attention through sacrifice, ritual, or self-mutilation. The Order is considered dangerous and fanatic although not all members are extremists and instead appeal to her more neutral side, hoping to avoid her wrath due to the immense power she possesses.
