---------------------------------------------------

Hueco Mundo had always been a cruel place, a kill or be killed environment that was fully understood by its inhabitants. It didn't need any outside influence, and whatever its rulers where, they were understood. With an underlying respect, everything followed its own justice and goals, yet very rarely did any hollow cross the invisible boundary that defied Hueco Mundo. If anything did, it was instantly gone, destroyed by its own arrogance.

Hollow could respect hollow, they could hate each other, but still understand goals and feel empathy. They could submit without feeling shamed, or die honorably to a hollow, finishing their existance. Their only goals were to become as strong as possible and consume, anything extra was a blessing, they had no need for anyone else yet they seemed to live very closely knit at times, but realized themselves before humans did, and realized their purpose and excepted it. Because the way things are, are the way things are.

Hollow did not respect shinigami though.

Like Yin and Yang, they were too different to co-exisist peacefully. Despite any foreboding any hollow had; they would attack any shinigami on sight, no matter the difference in strength or feelings toward them, they would kill them instinctively. As part of their purpose was to kill them.

So when Shinigami walked on hollow ground, they should expect to die. A place filled with nothing but enemies; it was a fools hope to walk out unscathed.

But three walked in. Walking close together to not present any opening, zanpaktou at their sides meanacingly. Hollow sprung up instantly to strike them down, but any attempt they made was cut down. They made no sign of joy or pity, but continued on, seemingly immortal. They were not extravagant, they did not boast their pleasure at staying alive for so long, but walked on toward Las Noches. Their appearence made little sense to hollow that did not attack, the stronger ones with a head on their shoulders watched as they continued to walk without pause. They hailed the end of a Hueco Mundo for hollow, an omen of a future that was not their own.

They walked into Las Noches and claimed it instantly, cutting down any that would oppose and instantly giving orders to have their bodies strung up and burned outside, to show who was the main power now. For many days the hollow could not understand this take over and planned many attacks to kill these shinigami. But all failed, all were burned or put on display. The attacks lessened until resistance no longer came, it was a futile effort, a realization. There was now respect in the place of confusion, but there was still fear on all sides.

One was the ruler, the new king. He never showed an angry face, never expressed any emotion not clouded with moderation. His brown eyes very frightening, but questioning and inquisitive at the same time. He carried no ill will to the hollow, but no one could be sure. But anyone in his presence would feel instantly safe and accepting so long as he wanted them.

He left the devilry to his comrades, the silver haired one, seemingly without eyes, his face forever folded in a constant smile, but there was no intent to love behind it. The other was cold to others, tall, black and blind, but with the dispostition of a man who could see more then anyone else.

They waited patiently until the attacks stopped, waited until they had a few hollow under their constant command. They waited until there was no hope for reformation. Then issued orders. The strongest hollow were to converge on Las Noches for a tournament to find the strongest, a rumour passed, hinting the beginning of an army, many were hesitant, fearing death or commitment. But they were pushed out of the shadows, given numbers, and told to fight.

Many felt it was a perversion of the hollow strength; being told to entertain the new shinigami overlords. Many seemed to take it as an opportunity to get on the good side of the newcomers. No rule stated any fight must continue till one died, but the opponents made it so.

Ten hollow finished and they eagerly awaited fighting to the death until one was left, many excited to spill blood and please the shinigami, but the leader held up his hand. The tournaments ended, a new force they had not yet seen that was much more frightening, the power to stop a fight without force.

The hollows that came to watch dispersed, the losers left to die, while the ten where taken with the leader. They entered Las Noches, with an overwhelming fear, the same atmosphere the shinigami carried intensified by a thousand in close company. Each were told to strip of any clothing they had, baring themselves before their new king. They lined up in order of power, none looking at one another.

They were branded. Then made to bow, curving inward to accept their fate. The leader explained the importance of their duty as the strongest and kept the attention of everyone in the room. They were the espada, the real espada. The shinigami disbanned any others before them and banished them to serve the new espada or be gone. They allowed the Espada to pick any hollow they wanted, they would be taken, and made into arrancar. Any objections would be cut down, it was for the good of Hueco Mundo.

Many things were now for the good of Hueco Mundo, new terrible things were being set in motion, new fusion hollow, advancements in zanpaktou, and expirements kept between a select few arrancar and the shinigami. The hollow outside of Las Noches, moved into shadow, fearing death or expirimentation. Espada were made and enhanced so when one fell short, they were replaced or killed. No Hollow was able to object. Their purpose now changed from the simple understanding of hollow, to creature made to please, to serve. They were now any army to serve the outcast shinigami.

Szayel was slightly unnerved at the prospect of meeting Aizen scared any hollow. His normal perky attitude had dissolved and he straightned his coat a little, the more professional the better. Aizen loved everything neat and orderly, taken care of before he asked. He expected he would like the results of the animal release zanpaktou expiriment he had been conducting, but felt that this might not need a formal appointment. He didn't know why he was worrying so much, he knew Aizen liked him.

He grabbed his clip board and notes he had from the expirement, even though he hadn't been told to bring it, then instructed some of his fraccion to run a bath for him upon his return, which he expected would be a half hour from now. Reminding himself that it would probably be less then that.

Just a report...

"Szayel,"

Szayel bowed low, letting himself up and parting his hair behind his ear carefully. He didn't say anything, allowing Aizen to talk first and explain while he stood quietly. He was comforted by the fact he allowed Menoly and Loli stay in the room, normally meaning he didn't mean any harm to the guest.

"I have a new expirement for you to preform." Aizen said plainly, readjusting himself on his pedestal-chair. Szayel, looked up, not letting his face pass any emotion.

"Even while I'm still testing another?" he asked carefully. Aizen nodded, picking up a folder of papers that lay on the arm of the chair.

"This expirement is of higher importance." He said "It is the work of the man you replaced. Just recently we finished going through his old documents and we found quite the find."

Szayel feigned interest.

"It concerns a sort of arrancar procreation that could prove very useful. The results could wield a power greater then the vastolorde, simply put."

Szayel frowned slightly. Arrancar procreation? Like children and babies? That didn't sound right.

"Please elaborate," He said quietly. Aizen gave a small smirk, which Szayel didn't like, he averted his eyes slightly, not meeting his eyes, but more accurately the strand of brown hair between them.

"He was researching a sucessful ectopic pregnancy in arrancar males." Aizen explained "In his notes he explains a surgery capable of making a life inside males while keeping testosterone at a low level in the body."

Szayel blinked, still confused. Aizen only smiled more.

"We'd like to see if this can be done as it can mean a new era of warriors. Shinigami and hollow blood; mixed, not forced together. It is a very interesting investment of preformed correctly."

"A new race of warrior created with surgical interference?" Szayel said quietly, feeling Menoly and Loli staring at him from the door. Aizen nodded.

"But I don't understand what you need me for." Szayel murmered, looking at floor, feeling stupid. "I can interpret the notes if you need to, but I'm not familiar with surgery enough to make this work. Do I just need to calculate for you?"

Aizen sighed, his eyes fluttering shut, he wasn't smiling, but wasn't frowning. Szayel felt uneasy, this really didn't feel right.

"I have the notes and surgery figured out, the medical staff can do preform this fine. The notes aren't that hard to figure out."

Szayel dropped his head in apology.

"With your scientific knowledge, and understanding of expirimentation and appreciation for your field, I would like you to volunteer."

The bottom dropped out of Szayel's stomach, letting his guard down, his eyes showed a fraction of the terror he felt. Surgery? Pregnancy? Expirementation? He was a science lover but not this, this wasn't what he wanted! He was always the one in the backround with a clipboard, taking observations and examining facts, he wasn't a guinea pig. But Aizen had used those words, I'd like you to volunteer.

Whatever Aizen wanted, Aizen got, it was just that simple. It was set in concrete now. He felt like his insides were being twisted. He knew enough to produce a deep bow so he wouldn't seem rude.

"I...will...do as you wish..." he breathed to his shoes, his pink locks of hair invading his face.

Aizen made a smile that could make Gin jealous.

"Good, I appreciate your cooperation in this matter. Please free up your schedule for surgery on saturday, and please refrain from eating on friday."

Szayel nodded mechanically. Bowing again and turning slowly, making his way at the door, not catching Menoly or Loli's smirking faces on the way out.

Long Prologue. No Definite Guarantee when this will get updated, reviews make me write faster. I'm in a weird fanfic mood because I recently watched The Handmaid's Tale and I'm reading Children of Men.

Sorry if the first part seems very pointless, it just gives some backround since this is kinda an AU fic.

Review if you feel its necessary. If you'd like Szayel to have multiples or a girl or a boy, you can say so, but no gurantee on whether I'll write it or not.

I feel dumb starting a fic like this, I have to work around school and stuff. But anyway. I hope you like it.

Kishire!
