The quori are nightmarish beings from the plane of Dal Quor, the Region of Dreams. The quori lifecycle is somehow connected to Eberron, specifically each new Age on Eberron changes the nature of Dal’Quor, causing the otherwise immortal Quori to die and be reborn into a form more fitting to the new age.
As the divine rulers of Riedra, the Quori act openly, sending their supernaturally charming Inspired Ambassadors to the courts of Khorvaire as benevolent allies. The Inspired offer a portion of their vast resources at generous prices to aid the war-torn continent. They act as impartial observers and mediators in negotiations between the nations, integrating themselves with Khorvaire’s political elite.
