The Sun God, who holds the power over life and the eternal scorching sun, has an extremely special position in this world.
He is seen as the protector of life, the judge who banishes evil and corruption. His Church is the most dominant divine force in this region.
As a lord, you may resent the interference of the divine in your territory, but often you cannot refuse the services of loyal and useful Holy Fire Knights.
Unlike Earth's "dazzling galaxy of stars," the world of deities in this realm has long formed a system—a pyramid structure of more at the bottom and less at the top.
From the ancient Four Pillar Gods to today's Seven Pillar Gods, the Eternal Scorching Sun has always stood at the apex of all deities, and naturally at the apex of this world as well.
Those Earthly gods always occupy a "secondary position." One can say that planets and worlds are related to them, but not owned by them.
