Belvestianism is a polytheistic religion. It originated in the Northern continent, though it is now cosmopolitan throughout Selt because of the widespread seafairing activities of the Belites.
In the Belite lands, it is the majority religion. It is a substantial minority in the Murinal Empire.
The Belite pantheon is headed by Belvest, originally a tribal god of the Belites and the king of their pantheon.
