The Construct

The Construct, otherwise known as Aether's Construct, is a geometrically undefined container of potentially infinite size, formulated by unknown means involving harnessing the energy of The Expanse to create an impenetrable barrier of "default" metallic-like material.

Geography
The Construct hosts a small array of experiments and sub-realms such as The Simulation, although later in the lore (circa Rotale lore) it hosts billions of souls in a countless field of sub-realms, including special "quarantine" realms for keeping anomalous souls such as The Protagonist in a place where they are unable to affect the rest of The Construct.

Sub-locations
The Construct contains The Simulation, and is interconnected to The Nihility for the intended purpose of cleaning memory, although this link is frequently abused by the inhabitants of The Simulation.
