An instance of the dimension that follows different physics or logic, typically used for explaining magic or other supernatural phenomenon.
For example, a theoretical domain could be one where each and every point in the dimension’s space is consolidated into one singular, infinitesimal point. If this domain of the dimension were to exist, then that means every point in space would be connected at the same root, regardless of distance. And theoretically, by accessing such a domain, one could hop from one point within the dimension to any other instantaneously.
