In fact the bodies represented in METACHAOS, even though they are characterized by an apparently anthropomorphous appearance, in reality they are without identity and conscience. They exist confined in a spaceless and timeless state, an hostile and decadent hyperuranium where a fortress, in perpetual movement, dominates the landscape in defense of a supercelestial, harmonic but fragile parallel dimension. In its destructive instinct of violating the dimensional limbo, the mutant horde penetrates the intimacy of the fortress, laying siege like a virus. Similar to the balance of a philological continuum in human species, bringing the status of things back to the primordial broth.
So that explains it, then.
