Inber

The Inber were the physical manifestations of Inanim's thoughts. They penetrated walls and filled half of Sphaera, and become the Mare.

It is unclear as to why Inanim's thoughts no longer penetrate Sphaera's "membrane." One excepted explanation is that Inanim is no longer thinking of Sphaera, and has moved on to create another realm. Another explanation is that Inanim is Sphaera.
