It has been said that the fluttering of a butterfly's wings could cause a tornado on the other side of a planet. That a single change could rewrite a person's entire life.

The brunette gasped in pain, her body contracting heavily in response. "You must push," the medical droid next to her, a Chroon-Tan B-Machine, tonelessly urged its agonized patient.

The words reached her through the pain, and she tried to push through the haze of agony, before she screamed and fell silent, gasping, "I…can't!"

She shuddered violently, "Where is he? Ani! An-" her desperate pleadings for a husband that would never come were interrupted by another contraction.

From the sidelines, a ginger-haired man watched, torn between worry and mind-numbing sadness at his failure. Why? Why hadn't he seen the signs? Why hadn't he tried to be a better mentor? Act as a true father-figure to him, as his own teacher had, like that man who had eventually turned his student to the Dark Side?

Hands clutching at the table beneath her, Padme Skywalker let out another agonized scream, far louder than any of her previous cries, that interrupted Obi-Wan Kenobi's dark musings. As her spasms eased, a second cry pierced through the fog that clouded Obi-Wan's mind. He moved over to the midwife droid, who passed him a small form wrapped in a white towel.

As he shifted to where the head of the newborn's mother lay, the baby suddenly halted its crying and opened its eyes. The bright blue irises of startling intensity stunned Obi-Wan. He had only seen that exact colour once before. The eyes were carbon copies of the child's father's. Eyes that Obi-Wan had not seen since before he'd left for his final confrontation with General Grievous. Shaking himself mentally before he could lapse into memories of burning and sickly yellow, he placed the baby next to Padme's head.

A single change.

"It's a girl," Obi-Wan told her, begging the Force to let the inheritor of Anakin's eyes grow up with at least one of her parents.

"Leia," Padme gasped, her face breaking into a pain-ridden, but sincere, smile, "Oh, my sweet Leia … " She reached out to touch her daughter's face, only lingering a brief moment before another contraction wracked her body.

A few seconds later, the cry of another infant filled the room. Obi-Wan took the child from the droid and laid it next to its sister and mother.

"It's a boy," he was having trouble forming the words as he saw Padme fading away before him.

"Luke … oh Luke," she whispered. Luke's wails quieted down almost immediately, his eyes stretched as wide as they could at the women smiling tiredly at him. In any other situation, it would've been comical, but there wasn't a single person in the birthing or observing room who was capable of bringing themselves to even think about smiling.

Padme moved her fingers to her babies' hands and their tiny fingers wrapped around one of hers instinctively as they cooed at her, "They're beautiful … Ani would be so proud … " her voice was growing fainter with every word.

"Obi-Wan … " she turned her head weakly towards the Jedi master, "There's good in him … I know … I know there's still … " Padme Skywalker's voice faded off as she passed away, and her hands slackened in the grip of the newborns' small hands.

Her twins, Leia and Luke, immediately began crying, harder and more distraught than their previous howls. Obi-Wan fought off the impending numbness, and picked up the twins. Leia calmed down a little, no longer wailing, although tears still streamed down her face. Luke only cried harder, his cries becoming more and more heart-rending.

His steps heavy, Obi-Wan left the birthing room. He met Bail Organa and Yoda in the observation room, both looking older and more worn down than when he last saw them. Yoda took one look at the newborns, sighed heavily, and beckoned for Obi-Wan to follow him to the conference room on Bail's ship. Bail did his best to fight off the sadness welling within him, and offered to take one of the twins. Obi-Wan passed Luke to him, whose wails were quieting down to whimpers.

After giving the babies to a waiting nurse, the Jedi and the senator followed Yoda, both silent and lost in their mourning. Upon reaching the white room, Obi-Wan and Bail sat in the chairs by the wizened Master. They didn't speak, too overwhelmed by the tragedy that had taken place.

Eventually, Yoda ‒ hunched over and seeming older than ever ‒ spoke, "Hidden, safe, the children must be kept. If learn of them the Emperor does, take them he will. In the Force, strong they will be. Split up, they must be. Together, too noticeable."

Can rewrite the destiny of an entire galaxy.

Obi-Wan spoke up, his voice rough with grief, "I will take the girl to Tatooine. She has family there. I will watch over her."

Yoda considered the younger Jedi, who stared back at him, unyielding.

"Train her, you will?" he eventually asked.

Obi-Wan gave a stiff nod, his features displaying the stubborn countenance developed over years of exposure to his former Padawan and Master.

The green Jedi looked at the ginger haired one, and nodded wearily, "For the best, this may be."

Bail spoke up, breaking the short silence that followed Yoda's agreement, "I will take the boy and raise him as my own. My wife and I have longed for a child for many years. He will be safe with us."

The two Masters nodded their agreement.

"Into exile I will go," Yoda declared, looking down at the table, "In hiding I will stay, until lifted the darkness has."

"Master Yoda," the blue clad senator began hesitantly, "with all due respect, do you honestly think that the Emperor can be beaten?"

Yoda hummed, and then stated, with absolute certainty, "Have faith we must. If lose faith you do, lose the war you will. Take care of the children, and fall, one day the Emperor will."

Bail and Obi-Wan stood and bowed to Yoda, and began to make their way out of the room. But before Obi-Wan could exit, Yoda called him back.

"Is there something more, Master?"

"Come closer, Obi-Wan. Have more to teach you, I do."

Obi-Wan Kenobi gazed over the desolate desert, the small homestead outlined against the setting sun. A woman, Beru Lars, was waiting for him at the doorway.

He walked up to her, holding his precious bundle in his cloak. Passing Leia to her aunt, he bowed deeply.

Before Beru could turn away, the man stopped her, "Could I see her? It doesn't have to be often." She's all I have left of him.

The young woman studied him, passionate eyes trying to reach into his soul. Appearing to hear his unspoken words, she nodded, a kind smile gracing her face.

Obi-Wan bowed again, grateful beyond words. He turned away, heading back to the waiting eopie. Getting on, he turned the creature to the Jundland Wastes, where he would remain until the time was right.

Riding the eopie to his exile, Obi-Wan turned back to see Beru handing her husband his niece. A small grin flitted across his features and he looked towards the sunset.

Rest well, little Leia. I will not fail you as I did your father.

AN: So, this idea came from an incredibly long class, in which I got a sudden idea. This idea was so ridiculous (and stupid as my dad put it) that it was hilarious. If Leia and Luke switched genders, then they would still be Leia and Luke. Fem!Luke would be Leia and Male!Leia would be Luke. This idea literally kept bugging me until I wrote this.

I am likely going to be changing other things (and not just the (maybe?) obvious), so be prepared!

Don't get me wrong, I love both of the characters the way they are (Leia is a major role model for me), I just really wanted to try this. Maybe one day I may write a fanfic with Canon!Leia as having taken Canon!Luke's place, maybe not.

Thank you very much for reading ^_^
