The Sovereign Host
The Sovereign Host is the only known pantheon of gods on Eberron. They are a marked contrast to the majority of deities in the rest of the D&D campaign worlds due to the fact that they are removed, distant, and uninvolved in the affairs of Eberron. This has lead some fans to speculate that the Sovereign Host does not actually exist and the power of clerics that worship them are provided by some other force. This is unlikely due to the near universal nature of Sovereign Host worship across the world of Eberron.
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 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.Variant Sects Sarlona, in the region of Pyrine. Pyrine is currently a bastion of the Path of Inspiration and is one of the most entirely converted regions of the Riedran Empire, but if the scholars and historians are to be believed, there are likely ruins and artifacts important to the faith still extant in Pyrine and its surrounding regions.
