The Oppositeverse is a verse where quantum mechanics affects larger structures more than smaller. In other words, the effects of the quantum world is mapped onto the macroscopic world.
Since life exists in the center point between the microscopic and macroscopic, life exists just as abundantly as life in a normal verse.
The unfortunate fact is, that as size increases, so do the effects, but exponentially. This means that beings are permanently trapped within the Oppositeverse, as the edges of the Oppositeverse possess infinite chaos and disorder.
