The full Concept of disgust, The Bleached Janitor in its simplified form looks like several clear plastic containers filled with various chemicals underneath a white lab coat, hovering above the collar of the lab coat is half a porcelain mask with a detergent pod behind its single eye socket.
The Bleached Janitor's mere presence causes disease, dirt, and grime to disappear around it.
Bugs die and vanish, rats run away.
The Bleached Janitor used to see all life in the same way someone sees a cockroach, gross. And thus it would sterilize entire universes of life in a few seconds each, leaving countless deadrealms in its wake.
Eventually, The Bleached Janitor learned that it was made of the emotion of the same sapient beings it found gross, so it made a realization. It didn't find their minds disgusting, it was the bodies that would eventually rot, the mind resists rot by its very nature.
There was still one problem...
mind was made with the body, rather than the body built by the mind. There were a few failures, one of which became a full concept itself. But it found a perfect solution, The Bleached Janitor is the reason why most realms are split between Etheria and Physica.
The Bleached Janitor is the reason why minds become Souls when the body dies.
