The Expanse

The Expanse represents the energy that powers The Normality, and thus it's deeper layers such as The Construct and The Simulation. It is an accessible realm by some, although entering it usually spells out death or insanity. Very few inhabitants of The Normality are able to harness the power of The Expanse, but most who learn how to are immediately erased by higher powers out of safety concern.

Geography
Up until the beginning of The Construct, The Expanse had no defining land marks, it is a highly abrasive, potent and endless source of energy that keeps The Normality and it's functions running.

Sub-locations
Inside The Expanse exists The Construct, and within that The Simulation. Aside from that, The Expanse is still an endless white void, so finding anything else unless an awakened individual were to bring you there is highly improbable.
