They fanatically believed in the Light Lord God, believing that the Light Lord God could bring light, peace, and warmth to the world, while followers of other religions were heretics and criminals who incited war.
As a result, in the Human Kingdom, the Church of Radiance became the strongest and untouchable church, obtaining the Power of Faith that no other church or person could challenge.
Soon after, the powers granted to humans by the gods were withdrawn, except for the Holy Woman and Pope of the Church of Radiance, leaving humans without the power to protect themselves.
According to historical records, a Pope of the Church of Radiance spread the news that the gods withdrew their power because they saw that granting power to believers in the lower realm would lead to war, and thus they took back their power to make everyone love peace.
