Dragon Eyrie(Plane)

The Dragon Eyrie is home to the Dragon Idols Pantheon, for the most part. Each Idol has a domain, at least. Asgorath, Astiballor, and Zorquan's bodies are ensconced within the Eyrie's depths, and continue to provide subtle magic and guidance for the dragons who live there. The Eyrie is an impossibly large mountain which occasionally plateaus in places to house a desert, tundra, or ocean, and is split into these physical regions to give home to the many dragons of the plane. These are not planar layers, simply impossibly large divides in the physicality of the plane, which dragons can cross via flying or whatever.
