Time Variance Authority

The Time Variance Authority is an infinitely vast bureaucracy that governs a significant number of realities in the ever growing reality. The organisation has dedicated itself to keeping tabs on every timeline that exists. It controls a temporal dominion which is approximately two or three times as large as Kang's temporal empire. All employees are born and bred specifically to complete their functions. Every employee in the TVA has lifetime employment. It is an organization of faceless bureaucrats. Most TVA employees are cloned from the same genetic stalk to reduce disputes and improve efficiency. However, they do recruit new promising candidates such as Justice Peace.

History
The TVA claims responsibility for monitoring the realities and can prune timelines if they are deemed too dangerous to exist. They also take action to prevent other beings from altering the past or future.

Despite their claims, the TVA's influence over time is not absolute. The scope of their influence is bordered by Alioth in the distant past as well as Kang the Conqueror, the Delubric Consortium, and Revelation at different eras throughout the timescape. There have also been numerous incidents of time travel or reality tampering where the TVA has failed to interfere.

At the End of Time, the last Director of the TVA creates the Time Keepers, the last three beings who exist in the remaining timeline in the universe; however this process also ends up creating the Time Twisters, a trio of beings who imperiled all realities until stopped by Thor and other members of the Avengers.
