The Sacred Spark is unique among religious organizations of Eberron in that it worships a deity from both the Sovereign Host and the Dark Six adopting Onatar and the Fury as two sides of the same divine force. Claiming that the great achievements of our world are not simply products of Onatar's blessing, for what is industry without passion to drive it, nor the product of the Fury's passion, because what is passion without a focused and direct application. Acolytes of the Sacred Spark are shunned by vassals of the Sovereign Host as dangerous and a bit insane while worshippers of the Fury among the Dark Six claim that its mere existance is a blasphemy against her holy name. The group is relatively small and fairly unknown across Khorvaire.
