Disclaimer: I do not own anything from Chris Nolan, Batman,or the DC Comics world. All chracters, plots and story lines used that belong to them...well belongs to them. I just own my plot and my interpretation of known characters and appreciation to Chris Tripitaka Le for the fan art i used my cover for this story.I don't know him,but it was amazing art and captured my vision of Cassandra perfectly.

That being said this is my first Fanficiton ever.I was going to label it a crossover, because the characters I used are already established characters in the DC comics world, but decided against 's all Batman in a sense. I crossed Chris Nolan's Batman/Dark night with the comics Batman for character and back story prposes. For example, I used Cassandra Cain and she has her abilities from the comics, but she is not mute and she falls in love with Bain. So in short abilities:Comics, World/location: Chris Nolan's, Personality: mine. Plot is all mine as well. However, I don't really know where this is going at the moment, but i'm excited on taking this journey with who ever reads. Feel free to review. I can only get better, as a writer, if I know what I need to work on. The fic is primarily a bane/ OC ,but takes place over the course of all three movies starting in Batman Begins. I estimate the first interaction between my heroine and Bane will occur during chapter 4. Hang in there all you die hard bane/ oc fans, it's coming. Thank you for your time in reading this and hope you enjoy!

Prologue

David Cain stood holding his daughter in the temple's infirmary. Midwives were frantically attending to Sandra Cain who lay in exhaustion as she prepared to deliver the after birth. Then the reparative surgeries would begin. The Cains knew they had to be of sound mind and body to prepare for the weeks ahead and no one had to be reminded how important it was to their cause that all went as planned. So of course David and Sandra knew sacrifices must be made. They knew nothing of their child's part in the overall plan content in knowledge that she had one. The temple surgeon then entered as his aids prepped her for surgery. Sandra was anesthetized. Stealing another glance at her daughter in her husband's arms, their eyes met for a brief second as the baby opened her eyes for the first time and Sandra slowly drifted off to a dreamless sleep.

"Ah, so I see the new arrival is here," Ra's exclaimed entering the room. "You have excellent timing, little one. Everything is going as planned." Ra's observed the infant in awe. She was striking. She was so like her mother. Cassandra cooed softly as she too observed Ra's.

You see Cassandra would take useful many useful abilities from her father, but only one important one from her mom; her eyes. Not the shape or the color, but more of how she uses them. To Sandra they were a deductive gateway to a person's inner desires, actions, and reactions. She used this in battle quite often and it usually proved her victorious. He recognized the look Cassandra was giving him; it was almost knowing. Yes, she was like Sandra and that was as he had expected. However, he sensed something else in her; something different, yet powerful radiating off the infant. A look of confusion crossed Ra's face. He furrowed his brow. Ra's found himself slightly hypnotized with every melodic coo that escaped the baby's mouth. He lifted the infant in front of him cradling her neck.

"What is her name?" Ra's asked entranced to no one in particular.

"Cassandra, we named her after her mom."

Ra's pondered this pulling from his brain his knowledge of name meanings. "It is a perfect choice in name, "One who is all". Much is depending on our Cassandra. Let's hope she lives up to it." The force strengthened. It drew Ra's attention back to her. He suddenly felt the need to protect her bend to her every beck and call. She wanted something. Ra's was sure of it. Cassandra crunched up her face, wiggled a little in his hands, turned her head towards her mother, and started crying: melodic and forceful.

Ra's had experienced a sensation like this before, but not for some centuries. He quickly shielded his mind and observed. The midwives immediately left the room as if in a trance. Her cry seemed to be a song, and everyone left in the room seemed to be ensnared in it. They all shifted and looked around between each other like they were having an internal battle between aiding the young infant and remembering their place amongst their leader. The event that happened next was the most surprising to Ra's. It started with Sandra as she was mother to the infant. Even unconscious, two wet spots appeared through her top as she started leaking colostrums. Next the midwives returned along with every other female member of the league of shadows, assassin or aide; all carrying milk in some form of container or leaking their own reserves. All the ladies were there to give the child what she willed. A look of realization settled on Ra's face. He stared at the child with a curiosity. He handed the small child to Doraline, her new caretaker for a bottle. Cassandra's eyes grew heavy as she suckled the milk hungrily. As soon as the crying had stopped, the one's seemingly in trances suddenly had their body control once again. Most wondering how they ended up in the infirmary holding bottles of milk and others slightly more embarrassed. It didn't take long for Ra's to fully comprehend what was placed right at his feet. The endless possibilities it held and that without a doubt he had to be the one to control it.

"Darcenda,take the infant and prepare her for the journey. She leaves tonight."

David shifted suddenly more alert and having a strong urge to protest. "Tonight? Ra's we didn't discuss this. Sandra, she was under the impression she would have some time with her. We know what must be done but…" David followed Darcenda trying to prevent her leaving the room with Cassandra. Ra's placed a gentle yet cautious hand on David's shoulder fully aware of what a man like David was capable. Darcenda moved down the hall pursued by David and Ra's after him. Emotions were running high. They could not afford a distraction at this point in the mission. "My friend, I don't have to tell you how vital you are to our plan. Many years of preparation will be needed and each of us must play our part," Ra's sighs before continuing "All of us must make sacrifices. Your particular mission, I cannot trust to anyone else but the best. It is vital to start the process of renewing Gotham."

David considered this for a moment. He looked back in the direction of his unconscious wife, but wasn't convinced. "It doesn't seem right to not at least let her say goodbye."

"I do understand my friend but I do feel it's better this way," Ra's paused a moment then continued. "for all involved. You see David, the bond between mother and child is strong; fortified long before birth. They only become stronger with further interaction. The longer we wait the harder it will become to do what must be done."

Indecision and confusion fogged David's mind. He sat down raking his hands through his red hair. He was not much for emotions. People had little use for them in his line of business; an unnecessary distraction. Sandra was like him. There never had to be any long expressions of sentiment. They married due to mutual acceptances: A silent understanding of each other's weaknesses and a great respect of each other's strengths. She was loyal. He thought back to before they were married. They'd always seem to find each other even during blind assault training. Sandra was one of two people to ever best him. In the toughest spots, He could always depend on her to be there. Word spread of them through the underground. Her instincts allowed her to anticipate his next move. He would start a fight sequence; she'd be there to complete it. He was darkness. She was silence. Separate they were deadly together they were invincible. Cassandra was the obvious choice in name when they found they were expecting a girl. She would be their first, if not only. She would be special. The perfect blend of two master assassins and it was fitting. One that is all. She would undoubtedly have all their strengths, but could be trained to have none of their weaknesses. Ra's knew the child would be special and so the plan was derived. Cassandra's service to the league of Shadows would begin at her birth.

They had months to prepare themselves for that day but now that it was upon them David felt a tinge of regret. He had been the first one to hold her. He studied her head: Her light brown curls with streaks of red through them, honey complexion, and hazel eyes. All at once, an array of emotions flooded him. Pride for one she had his nose. She was a piece of him, but so much of Sandra. Then he recognized Fear. He wanted to be there to protect her from anything that could hurt her. She could not cry not due to pain. Never. He'd cross oceans, climb mountains, even kill… if it would appease her.

David sat like this for a few minutes left to his thoughts. He could sense Ra's eyes on him; waiting on his consent more out of respect than necessity. He kept thinking like this for a few more minutes before it hit him. He was feeling. His eyes became a dark gray at the thought and it was at that moment Cassandra Cain became deadly to their cause and to their mission. A distraction he and Sandra had never had. One they couldn't allow. He knew what had to be done. Things were in motion it was too far in to be derailed now. Cassandra had to leave. That's the only way they all could survive this. It's the only way Sandra would stay focused on what was ahead. Then, there it was again, a feeling, both underlying and annoying. He would send away his daughter for their mission. What was this, Guilt? He had ruthlessly snapped necks, decapitated, and dismembered bodies. Never once had he felt guilt. Sandra would understand. She was like him in that way. Sacrifices had to be made to ensure their purpose fulfilled.

Ra's continued to watch David, caution in his eyes. He knew the threat David was and was prepared to do what was necessary if David gave him the slightest reason to. This was going to happen with or without his permission.

With his last realization, David finally looked up concession on his face. He sighed and stood from his sitting position. "Very well, it is best this way. Now, if you excuse me. I must wait for her mother to wake up. She will want to know where her daughter is. It would be best if she hears it from me."

David started for the door and stopped just before walking through. He looked over towards Darcenda and regarded the infant peacefully sleeping in her arms. He smiled a sad knowing smile. He had to be sure. "What will become of her; just in case Sandra asks?" He asked Ra's over his shoulder not taking his eyes off of his daughter.

"The child has a bigger part to play in our mission as you already know. Her path leads to Gotham and with her special inheritances she will be most useful as a tool for inside infiltration of Gotham's elite.

"But how?" David interrupted, "She will not know about the league of shadows how will that aid our purpose?"

"I will be watching over the girl. Watch them, though the years, gain her trust and she theirs. When the time is right, I'll plant the seed. She will return to the league wounded, searching … willing; ready to join our cause and learn. All while carrying with her a store of knowledge on Gotham's so called elite. She will be raised with the most lavish opportunities, schools, and parties. Luxuries fit for a princess: The princess of Gotham to be more exact. She will want for nothing money can buy. I have assured it."

Ra's ended in tone that sounded distinctively fina. David couldn't help smiling to himself; his guilt eased , content with the knowledge that she'd be raised out of the way and safe. She deserved a life like that. He turned around fully to acknowledge Ra's, dropped his head slightly in quiet consent, and proceeded down the hall.

"Now, my dear, repeat back to me all I have just explained to you. I will not be accompanying you this trip, as I have business elsewhere to tend to. Gotham International is big and there is little room for error. All must go as planned. She is too vital to the mission. Begin." Ra's demanded Darcenda recited the itinerary:

"Upon landing at Gotham International, I will approach a driver holding the sign Stevenson. We will travel to Gotham general where we will be snuck into to the back entrance and greeted by our infiltrants Victoria Schulman who will be dressed as a nurse who works in the nursery. She will have a cart and in it will be balloons. I will place Cassandra in her hand and only her hand. She is to leave immediately with Cassandra. I grab the balloons and follow at a considerable distance behind her, but must never loose sight of Cassandra. We will travel to room 535; where the decoy biological mother will be in labor and after the birth of her child. Cassandra will be given the name tag meant for that child, and thus placed in the care of her adoptive parents."

"Very good." Ra's complimented her. "This might actually occur without a hitch, and what is the only stipulation that is to asked by the biological mother?"

"The child is to keep her first name. It is a family name and the mother wants a piece of her to stay with the child, even if she can't be" replied the caretaker.

Within a few hours,Darcenda had grown attached to the infant in her arms. It had been a long plane ride so far and they still had a couple of hours left.

She was genuinely concerned about the infant. She had always wanted a child and had grown used to caring for one, and wanted the feeling to last. Cassandra would be gone in a few hours and the void in her heart would start to ache again. Perhaps there was another way?

"Master, you said that there would be another child. What would become of her if Cassandra is to take her place?"

"Her biological mother decided months ago she wanted to keep her child, so it fit our plans and hers to receive the money of the adoptive parents, keep her child, and still have one to give. She was copperative enough to wait until Cassandra's birth to be endused to ensure a timely concern is not the other child. We must see that Cassandra makes it in perfect time to be switched. It's supposed to be a closed adoption. The baby will be taken immediately at birth. If she is not there all the planning is void."

A look of defeat crossed Darcenda's face. She considered this a little longer. Then a plan formed in her head. She held Cassandra a little closer and continued to watch the infant sleep. She was so beautiful. Perhaps, if all went as planned, she could check on her. Watch her grow. There was just one issue that stood in her way: It was a closed adoption she wouldn't see her ever again after she is taken from the room. She had to know who was adopting Cassandra and the only one who knew that was sitting across from her at that moment. It was now or never.

"Master, you never mentioned to David, who was adopting Cassandra. And I'm curious who in Gotham has the wealth and means to give her such a title as "The Princess of Gotham".

Ra's not even looking up from the book he was reading answered," That's simple my dear, Thomas and Martha Wayne."

One week Later:

The front page headline in the Gotham Gazette announced: "Gotham Hails the Arrival of its New Princess: Cassandra Isabella Wayne".

The article took up majority of the page; save two small headlines stuck on each side of the coupon of the day:"CEO sentenced in Major Embezzlement Case", and "Young woman and Infant Mysteriously Disappear from Hospital".

A/N: So that's it. The first chapter and I made it a prologue. Purely back story more to come, but bare with me. Let me know what you think. Any advice you might have again is appreciated. Don't really know what a Mary sue is classified as,but I have seen people try to avoid it with their characters so I too will try. She will have back bone and will live all but the perfect life since that part of the story you already know. No happily ever after for the Wayne family in the beginning. Chapter 2 coming soon.
