The TVA is an organization outside of time who's purpose is to keep the scared timelines and their respective branches alive and let them grow, let the multiverse grow, expand and flourish like a tree.
The TVA also keeps an eye out for a specific person in each universe named Nathaniel Richards, known as kang the Conqueror. All his variants/alternate counterparts must be found, so no Multiversal War starts
The Time Variance Authority exists outside of time and reality itself, they all have different departments and places everywhere. Each one watching over a specific main universe/sacred timeline and their branching timelines/alternate universes. They must watch these universes until their anchor, a very important being for a universe dies, making the timeline/universe wither away naturally
They watch every moment of a specific universe through monitors and can come in and out of a universe in whatever time period through tempads. Tempads are vital to every TVA personnel. They host information about the TVA HQ they’re stationed at, the timelines they watch, scanners, trackers, etc. But most importantly, they open gateways to a destination they want to go within the sacred timeline and/or its branches
There are agents and Minutemen in the TVA. Agents are investigators who are responsible for tracking down dangerous people that are a threat or causing harm to their universe or others. They are also involved in interrogation tactics and wear suits most of the time but are equipped with pruning sticks, they are devices that can work as tasers, slow down someone’s movement by whatever speed when they’re hit or can prune them. Pruning means that the person or object they touched with the stick is sent to the Void, a dumping ground for everything that is pruned by the TVA in a dead reality. The only way out of the Void is through a tempad and survival in the Void is low due to the roaming giant cloud monstrosity that is made up of anti-matter called Alioth or the various possibly dangerous groups that survived in the Void for so long that can find them
The Minutemen are the TVA’s security and Taskforce agency, they wear tactical gear and are trained as a unit to deal with any variant they’re ordered to bring in. They also carry pruning sticks, but collars that can strapped to their target. A remote comes with this collar that allows a Minuteman to teleport their prisoner back to them if they try to escape. Each Minutemen has a code that is followed by the word ‘Hunter’ with a letter and a serial number. (Ex. Hunter A-43, Hunter T-05)
A specific person that the TVA is tracking down, including his variants is Nathaniel Richards, otherwise known as Kang the Conqueror. He and his alternate counterparts are pure evil and want nothing but power and killed many people and started a Multiversal War. The TVA’s hunt for him and his counterparts will bring an end to the Multiversal War before the war starts
The TVA has a single AI but is very powerful and has access to almost everything, her name is Miss Minutes and she helps everyone in the TVA with their position. Miss Minutes takes the shape of an old cartoon clock
Everyone the TVA comes from a sacred timeline or its branches. They higher ups are those with the title of judge. Not only do they make the final decision whether the variant they captured is free, but wipe their memory from ever being in the TVA or needs to be pruned to the Void. But the judges in the TVA oversee what the other departments are doing and make sure that nothing shady is going on and approve of projects that might help the TVA
