The Aetherical Realm
The Aetherical Realm is a plane of existence that is tied to and parallel to our own Physical Realm. It is inhabited almost exclusively by Aetherians. The Aetherical Realm is not bound by the same laws of time and physics as our Physical Realm, thus, with proper instruction, the Aetherians can alter and manipulate the Physical Realm in almost any way.
Another inhabitant of the Aetherical Realm is the Dark Aetherians, or Daedrerians. The Daedrerians are Aetherians that serve the Dark Lord and are in constant battle with the Aetherians over control of the Aetherical Realm.
