Location
A location is a defined space.
It can range from microscopic to an entire universe, as such it can define any possible physical and spatial unit within reality, including worlds, regions, areas, maps, and navigable spaces.
Parallel universes
At a macro level the whole is divided into universes. At this moment in time it is unknown how many there are and even if counting them is a finite or worthwhile endeavour. What is know is that the majority is interconnected. Another mystery surrounding this subject is the question about if the connections are technological, natural or both and in what degree.
