Humans/Quincy:

The year is 3111. 1000 years have passed since the fall of Aizen and his espada. World War III almost wiped out the entire human population. They grew in numbers and in strength as the years after the war passed. With the advancements in their technology, the humans created special suits. These suits allowed every human to see spirits in order to protect themselves from hollow. For the humans who already possessed unique abilities, these suits magnified those abilities and allowed them full use of their powers. Even for those who do not possess unique abilities, the suits increased the average limitations of human power. Their strength, speed, agility, and stamina were increased. On top of their physical gains, humans became smarter and smarter with these suits, constantly making advancements. Technology began to increase exponentially by the month. Cures were found for cancer and new diseases were quickly taken care of with remedies. The life span of the humans grew to several hundred years. They could now travel into space where they currently had colonies on the moon and on mars that lived and prospered just like the humans on Earth.

Shinigami:

The humans became independent, no longer needing the shinigami to watch over them. Without having to make the humans their main concern, Soul Society began to make their own advancements. With the help of the current president of the Research and Development bureau, technological advances were quickly made. Soul Society no longer resembled feudal Japan, but now the old Karakura. Skyscrapers and street lights along with motorized vehicles. Soul Society had entered the 21st century a millennia after. Soul Society became impenetrable and was no longer in fear of intruders such as arrancar. However, they were far from a “peaceful” society. They still had to deal with rogue shinigami and vizard who were able to come and go as they pleased. With the improvements in living standards, Rukongai has also become a better living environment. No longer do the people live impoverished lives, instead they have all flourished and live the life of middle class. Very few civilians still scrounge for food off the streets. Even though Soul Society is safe from the hollow, the shinigami still train for the day that the arrancar infiltrate the Gotei 13. No matter how much their technology has advanced, it won’t be able to ward the hollow off forever, for they too continue to grow more powerful.

Hollow/Arrancar:

The arrancar, currently lead by two ruthless kings, have continued to grow stronger and stronger over the next millennia. The arrancar had realized that they could mate and create more powerful arrancar through purebred breeding. Instead of Gillian class hollow becoming arrancar, gaining their powers, these arrancar would be born with their power. As consequence, the arrancar race became split. Those who believed in only allowing pure blood arrancar live and kill the rest and those that believed that all should be allowed to live and be used to fight. Even with this civil war, the arrancar were still a power that was not to be taken lightly for they gained a new ally, this ally had only recently revealed themselves. They were the Hinrichten.

Hinrichten:

Five hundred years before the present timeline, a horrible race showed themselves to the world. They are known only as the Hinrichten. Their ruler, a man strong enough to have overthrown Lucifer himself, runs their race with an iron fist. They come from all depths of hell and have shown all the extent of their power. The Hinrichten rule the underworld, taking care of every sinner that comes their way. Much like the arrancar, this race is not one to be taken lightly. Their abilities are still unknown to the other races. The few souls that have come face to face with one of the Hinrichten have not lived to tell the tale. Their plans are not quite known, but what is known is that they are currently helping the arrancar in their conquest to take over, even during the midst of their civil war. However, one race has made it their duty to rid the world of the Hinrichten.

Vizard:

The Vizard too have grown in power. Realizing the full extent of their hollow selves, the stronger vizards have learned how to release their full vizard forms. However, very few vizards actually have managed to manipulate this power for it has driven most insane or turned them full hollow and unable to revert back. But, the Vizards, having noticed the uprising of the Hinrichten and their alliance with the arrancar have made it their duty to kill off all of the Hinrichten no matter what it takes.
