The Creation Myth

In the myth of the Progenitor Wyrms—a tale told in some form by nearly every culture—the three Progenitors work together. Siberys creates, Eberron nurtures and preserves, and Khyber consumes their works. After time unknown, their creation consisted of thirteen planes, each one an idealized exploration of a particular concept: Life and death, war and peace. Following this effort, they rest in the emptiness that lies at the center of the planes, and create the sun, Arrah, as a mortal would kindle a campfire. But there, the Progenitors quarrel. Khyber kills Siberys and tears him apart, becoming the ring around the planet and the source of magic. Eberron enfolds Khyber and becomes the world itself, forming a living prison she cannot escape, while Khyber becomes the inner world and source of fiends.

Whether this is truth or metaphor, it is a basic explanation for natural phenomenon.

• Eberron is the world and source of natural life. It is surrounded by the shattered Ring of Siberys, and it contains Khyber. Whether or not Eberron was once a noble dragon who imprisoned another dragon, it is a natural world that surrounds and imprisons a source of fiends and aberrations.
• Eberron—and its Material Plane—lies between the thirteen planes. It is influenced by all of them but it’s not part of any of them. It’s a world that knows both war and peace, life and death.
