Void Empire

The Mukō Teikoku (ボイド帝国, literally "Void Empire")is an incredibly powerful group of spiritual beings, that wish to make a statement in the new world. They are the first Protagonist of Bleach: Ephermal Nightmare. They are also the main Antagonists of Bleach: A Surreal Dream.

History
When Koda Ketsueki managed to convince Dominic Ketsueki to start a group with him, the Mukō Empire got wind of their prized member leaving, and decided to take him back. The conflict resulted in the Mukō Empire losing, and forced them to go into hiding. However, during that time the Mukō Empire was not at their full power. Most of their members had been off in search of a way to increase their Vast Reiryoku to the point where all of Hueco Mundo could be caught within their "Void Ability".

These members were known as the Feudal Lords, and held the entire Mukō Empire together. The moment they left the Mukō Empire had underwent something similar to a Civil War, splitting them into two groups. The first group was known as Mukō, for they were the ones who had the most strength, and kept the original teachings of the old Mukō Family. The second group, was known as Arufa, for they were the Alpha beings when it came to Reiatsu and Knowledge.

The two groups fought within each other, and the Arufa's ended up becoming part of the Saibankan, which did not please the Feudal Lords. When they returned, they went and slaughtered a majority of the Saibankan's men, leaving only the few that possessed the "Void" ability.

The conflict continued for 5 more years, and then finally the climatic battle was to begin. The Mukō Empire put together it's strongest fighting group, and called them the New Feudal Lords. However, their power was so unstable, that they couldn't hold themselves in an actual fight. This caused them to take a trip to Hell and gather the one person that actually had information on the Saibankan.

That Special Person was able to give them enough information to attack the Saibankan base, and allow them to get the advantage.

Goal
The family's main goal is to create another empire within the Soul Society, using the power of their Vast Reiryoku to overthrow the lesser Shinigami. However, since the Saibankan call themselves the "Judges" of Soul Society, their new goal is to get rid of them. They have been forced to incorporate Killing Intent into their Void ability. This shows that they are willing to kill anybody to achieve this goal, including Dominic Ketsueki

Technology

 * Quincy Cross: Much like other Spiritual Races, the Mukō Empire managed to get their hands on a Quincy's special cross. This cross allows every one of them to use the abilities of a Quincy. However, since not every one of them are Quincy, their power is not as strong as a normal Quincy's.
 * Modifactions: With the help of the Mukō Empire's scientists, the Quincy Cross has been modified to connect the Quincy Abilities of those with the same model. This simply means everybody in the Mukō Empire is able to share their power with another member. This was an idea given to them by their new Emperor.

Headquarters
The Mukō Empire resides within two giant domains. The first one is known as Hueco Mundo, and the second one is known as Mukō Tower. However, because of the Feudal Lord's Overwhelming Reiryoku, Mukō Tower's image has been distorted greatly. This makes it completely invisible to the naked eye, and even cuts off the target's sense of touch and sound, keeping them from bumping into it, or hearing the people inside.
