Aetheria exists outside of Time and Space; She is beyond our concept of existence.
Aetheria is The Voidwalker. Though her eyes are covered, she sees all; every birth, every death, every soul making its journey from one end to another beginning. She keeps watch over the spaces that exist outside of Life and Death- The Void. This realm cannot be seen by mortal beings, but exists all around us. It always has, and always will, for The Void is eternal.
Since before The Beginning, Aetheria has sworn not to interfere with the journey of a Soul. Although she is capable, she allows all Souls to pursue their own Journey. All are guaranteed Free Will. In fact, the very reason for Aetheria's existence is to ensure this. The journey of a Soul is sacred, after all.
