Postcreated or postcreated creature: Collective term for individually created, supernatural, (mostly) inorganic creatures. Their individual aspects vary wildly but none of them have biological functions. They can be roughly classified to real, surreal and ethereal types.
Essence: The "soul" of a postcreated, which is integrated into their body.
Real: "Skull-faced fantasy critter." Real-class postcreateds are one solid creature, with none to minimal possible floating parts, and may look like biological creature from afar.
Surreal: "Walking metal skeleton." Most often mostly or fully skeletal-looking body, with clear deattached floating parts.
Ethereal: "Semi-abstract whatever." Creatures with usually most abstract features. The defining feature is their forced ability to co-exist with their own side dimension, so their whole existence wouldn't interfere with reality and the laws of physics too much.
