The Church of the Celestials stands at the heart of Celestia’s spiritual life, honoring Helio, Luna, and Astra—the three Celestial Gods—within its awe-inspiring Grand Cathedral. Though it originates on a floating island in the theocracy of Celestia, its influence stretches across every major nation, making it the largest and most widely recognized faith in the realm. Nearly everyone, even those who primarily follow another religion, will make at least one pilgrimage to the Celestial Grand Cathedral to pay respects or marvel at its grandeur.

Helio, the Sun God, is venerated for his daily gift of light and warmth; Luna, the Moon Goddess, presides over mysteries, romance, and nocturnal guidance; and Astra, the Star Goddess, inspires acts of divination and prophecy. Fittingly, the Church’s symbol unites their domains: a stylized representation of the sun and moon against a star-filled sky. This symbolism likewise reflects the Church’s commitment to education—particularly its celebrated school of divination, where oracles and prophets study the patterns of the stars under Astra’s patronage. By intertwining ritual, pilgrimage, and academic pursuit, the Church of the Celestials offers a unifying spiritual framework that transcends borders, drawing worshippers from all lands to stand together beneath the sun, moon, and stars.
