Paradox space is the space outside of the omniverse containing everything that doesn't exist, outside of reality. It is called paradox space because the most overt generator of nonexistance is paradoxes, things that contain contradictions that prohibits them from ever forming inside the normal omniverse. The outer boundary of paradox space is the Box; paradox space can be thought of as the container of the nonexistant part of the Box, as reality is the container of the existant part.
