Eberron Pantheon

The Sovereign Host: The Sovereign hosts are the good/ neutral aligned deities of the 12. (Called 12 despite there being 14 because 2 houses are considered dead: Onatar is not recognized by the empire as a deity and Ollandra had no descendants.) They are the first recognized beings to achieve godhood , transcend the material, and found their schools of magic/ philosophy. They're praised by people who descend from their countries, and revered by the religious followers of the Sovereign host religion. They're often called saints, as the title of 'god' had a different meaning prior to their ascension. Each member of the imperial senate is a reflection/ descendant of one of these dieties, most prominently Emperor Aurelius, Son of Aureon.

Planes of Ebberon: The surrounding planes of Eberron are each represented as a moon that surrounds the worlds. Different religions interpret them differently, some view the different planes as their after life or a new realm of existence, circling the world in cycles. some just see them as moons with no meaning. However, whatever they believe, when the moon/ plane is coterminous( or closest to the material ) they produce strange effects on the lands they they become close to. Magic behaves strangely, and in some spots such as in Karrnathi, spirits walk the earth.
