The Veil is the common term for the membrane between the Universe and pocket universes. The term is also applied to the space between successive pocket universes which, if they exist, are accessed linearly. Objects in the veil effectively exist in two realities until transitioned to one or the other. Objects in the veil are not visible to either reality, though both realities are visible from the veil. Whichever reality is “closer” is the more sharply defined of the two.
