The Halcanni Pantheon was the dominant religion of Halcann before the Age of Unraveling, the pantheon was a combination of local gods and was widely spread through the efforts of the Damerian Republic and the Phoenix Empire.
The Pantheon met success due to its acceptance of foreign gods, as people joined the republic/empire their gods were absorbed into the Pantheon, some became gods in their own right while some were 'proven' to be avatars of existing deities and all were incorporated into the Halcanni Creation Myth.
By the time of Jaher's death the Halcanni Pantheon had truly earned its name, sharing deities from Cannor, Escann, Gerud and Sarhal.
