Dimensions

Existing in the metaphorical space between the Transitive Planes and smaller, finite demiplanes, dimensions are a category unto themselves, defying the neat categorization of planar scholars and adventurers. Seemingly infinite in scale, not necessarily spatial in the same way as a plane, and overlaying every other plane at once—including one another—dimensions and planes are most significantly differentiated in how each of them breaks the commonly held rules of the other.
