Starry Heart.

The Starry Heart is the name given to the caldera-like formation between Zimesh Nor and Dron, where it is said that Xaernes and Gael first met in battle, then in peace.

History
In a time before time, the primordial gods Caernes and Gael met and fought in the astral plane, their refuse forming the raw material of the mortal plane. Upon viewing their creation, they made an accord at the location of the Starry Heart to explore their creation together.

When the two left the material plane from the Ur Tower, the world was left to its devices. The Starry Heart, though, acted as an open faucet from other planar realities. Over the years, many drew power from this wellspring of magic and energy, and many moved through its portal into the material plane.
