Worshipers of the Sovereign Host are called Vassals and they are divided across a wide variety of churches and organizations across Eberron. There is no central hierarchy to worship of the various gods of the Sovereign Host and practices vary tremendously between sects.
The Sovereign Host is composed of nine gods but they formerly numbered thirteen before the casting out of four members of the Dark Six. The Traveler and the Shadow are not members of the Sovereign Host. The Shadow being the literal shadow of Aureon while the Traveler seems to have come from someplace else.
The Sovereign Host consists of the following gods:
* Arawei – Sovereign of Life and Love
* Aureon – Sovereign of Law and Lore
* Balinor – Sovereign of Horn and Hunt
* Boldrei – Sovereign of Hall and Hearth
* Kol Korran – Sovereign of World and Wealth
* Dol Arrah – Sovereign of Sun and Sacrifice
* Dol Dorn – Sovereign of Strength and Steel
* Olladra – Sovereign of Feast and Fortune
* Onatar – Sovereign of Fire and Forge
The Sovereign Host does not have an afterlife that promises paradise to followers. Instead, it is believed that all souls go to Dolurrh the Plane of the Dead regardless of their virtue in life. A heresy of the Sovereign Host suggests that the plane will eventually be touched by their presence and it will become a paradise that the dead can enjoy. Worshipers do not give offering to the Host for a pleasant afterlife but instead for material gain in this life.
In a surprising contrast, the Sovereign Host is a great deal less tolerant of other religions than the militant followers of the Silver Flame. Worshipers of the Sovereign Host believe that all other deities are (mis)interpretations or corruptions of members of the Host or the Dark Six. As such, certain militant sects like those of Dol Arrah or Dol Dorn have no problem with forced conversion.
Another heresy of the Sovereign Host depicts them as Dragons rather than people. This view is widely loathed by the average Vassal of the Host, however certain evidence suggesting that the Sovereign Host were originally founded on powerful dragons at the dawn of civilization is undeniable.
