Omnipresence

Summary
Omnipresence is the property of being present everywhere, whenever and nowhere at the same time, referring to an unbounded presence. The ability lets you to be everywhere at once that is, at every point in space during a given instant. Some characters are Omnipresent within a single universe, while others are Omnipresent on a Multiversal or even higher scale.

Nigh-Omnipresence is when somebody is almost everywhere at once. An example of this includes being Omnipresent within a city or a planet.

Occasionally, the term is used in a limited way, such as "omnipresent in a city" or "omnipresent across the earth". While this is technically incorrect, the meaning is obvious.
