Earth-616 the Main Marvel Universe (Part 2 of 2)
Cosmic entities
Above all other beings in the universe are the cosmic entities, beings of unbelievably great levels of power (the weakest can destroy planets) who exist to perform duties that maintain the existence of the universe. Most do not care at all about "lesser beings" such as humans, and as a consequence their acts can occasionally be dangerous to mortals.
When dire perils threaten the universe, it is not uncommon for these beings to gather together to discuss the threat, and even act.
Dimensions
Several dimensions coexist simultaneously without affecting each other directly, ranging from the Earth-like to the totally alien. Some are magical in nature and others are scientific; some are inhabited and others are not. These include realities like the Microverse, Darkforce Dimension, the Mojoverse, and many more.
Time
Another noteworthy feature of this universe is that time "branches out" creating new alternate realities when certain important events happen. Those realities can also spawn realities of their own. There exist hundreds, probably thousands, or even millions of such realities. It is unknown why this happens, though a warp known as the Nexus of All Realities exists in a swamp in Florida. For the most part this does not matter, as most beings are unaware that this occurs, or even that their universes were recently "born" from another. However, organizations exist which try to monitor or manipulate the various realities. These include the Captain Britain Corps, the Time Variance Authority, and Kang the Conqueror's forces.
