The All Father tore from his breast a rib and upon it hung long stands of his tissue. Those shreds hung from the long rib-like a curtain of light and he made it to pass through the void. This was the first of the Twin Sisters, Ea-Raena, the Maiden of Night. In time she bound herself into form and cast off the remaining shreds of the All Father’s tissue. And those shreds settled upon the Firmament and unbeknownst to her they wove together into a great net. So the Ethereal Plane was made, the Net of Ea-Raena. A plane of wild abandon, only the most hardy can live here for there is no air or light, only the unbridled language of creation. It continues to grow, being of the living substance of the All Father, but only the most learned have begun to unravel the mysteries of its origins or why it continues to spread across existence.
