Fiction:The Firmament/Heart of Creation

The Heart of Creation is the domain of the goddess Aether, the highest divinity of the Firmament.

Description
The Heart is an ever-shifting demiplane of primal magic where matter is constantly created and destroyed as Aether focuses on creating a perfect balance which can be applied to the entire Firmament. It is an exceptionally hostile landscape to mortals and even other divinities, who usually avoid the area at all costs.

Inhabitants
It is believed that there are no inhabitants in the Heart beyond Aether herself, for none are able to survive there for extended periods of time.
