Author's Note: This is my first fanfic ever, so go easy on me people. Constructive criticism is accepted and encouraged, but please no flames. That's just mean.

Disclaimer: Code Geass is owned by Sunrise, and I am not making any profit whatsoever on this. As for the book that I'm crossing with Geass, that's a secret, so I'll post a disclaimer for that next chapter. But I definitely do not own that either.

Destroyer of Worlds

By e7cg13

Prologue

Basked in the orange glow of the twilight sun was the bloodied site of a brutal, one-sided skirmish, further reinforcing the idea that, yes, war is hell. The desolate landscape which served as the backdrop for this violent conflict was filled with the sounds of artillery fire, airstrikes, and the clash of armored fighting vehicles and Britannian knightmare frames.

The battle was merely one of many which were fought between the Britannian invasion force and the remnants of the Japanese military, who refused to surrender despite the death of their prime minister, Genbu Kururugi. However, in another universe, an alternate reality, this particular battle would have never taken place at all. The consequences of this divergence in history will greatly affect not just the world, but the entire galaxy.

"Big brother, what is that noise in the background?"

The speaker was a little girl, probably no older than 7, who was currently piggy back riding on her 10 year old brothers back. She was blind and obviously incapable of walking.

"Don't worry Nunnally, that's just the fighting. We'll be safe here 'cuz we're too far away," said the raven-haired youth, obviously lying in order to reassure his delicate little sister, "We just need to get out of here and find a way to meet up with the Ashford family. Then we'll be safe. I won't let anyone hurt you."

The two siblings were trekking their way through the edges of the battle zone, too far away to be directly involved in the skirmish, but at the same time still in great danger. Prior to their current predicament, the two were being escorted by a Japanese convoy to a safe house where they would seek asylum with the Ashfords.

But the convoy had been attacked by Britannian forces, and in the ensuing chaos, Lelouch and Nunnally found themselves separated from their protectors and forced to escape the danger zone alone and on foot. On top of that, Lelouch had to carry his crippled sister on his back as they had lost the gentle girl's wheelchair. Despite his determination, the unathletic boy was already struggling to support his sister's weight along with his own fatigue.

"Brother, are you alright? You seem out of breath. Are you sure we should keep going? We could stop here and take a break if it's too difficult carrying me."

"I'm fine Nunnally, I said not to worry. We can't stop here anyways, the battle is too close. It's too dangerous to take a break. I can manage," replied Lelouch.

Nunnally accepted Lelouch's answer, but was still upset. She hated being a burden to her older brother. She would rather have Lelouch just leave her there so he could escape on his own, but she knew her overprotective sibling would never go for it.

That's when her sensitive ears heard it. At first it was a faint noise that seemed insignificant in comparison to the cacophony of the battlefield, but then became louder and louder until it was a sharp whistle. Lelouch didn't seem to notice it, so Nunnally decided to voice her concerns.

"Umm, brother, do you hear that strange noise. I don't know what it is, but I think something is comi-," BOOM! Suddenly, a stray artillery shell impacts several meters from their location. It explodes with immense force and heat, peppering the hapless vi Britannia siblings with deadly shrapnel. Lelouch is instantly knocked off his feet, taking Nunnally with him. Once again, Nunnally is shielded from fatal damage by the body of a loved one.

Meanwhile, surveying the battlefield from a more secure location was a woman; a very unusual woman. She was very tall and possessed unnatural beauty. In her right hand she carried a small brief case. The women suddenly flinched, as if sensing something important, than made her way closer to the fighting, where two royal siblings lay on the ground; one of them in critical condition.

Nunnally was in immense pain. The former princess had not felt anything this excruciatingly painful since…since her mother's own demise. But the pain couldn't compare to her fear for Lelouch's condition. Nunnally's beloved older brother was still sprawled on top of her, just like her mother had been when she died, and he hadn't said anything since they were hit. He hadn't even asked her if she was okay. Lelouch was obviously unconscious, and if the prince's blood all over her was any indication, he was also dying.

The blind girl prayed to every god she believed in to save her brother. She didn't know what she would do without Lelouch and his kindness and love for her. The very thought of a world without him was…NO! She didn't want to think of a world devoid of Lelouch vi Britannian. It just wasn't possible. He had to survive!

"Lelouch, please wake up! You can't die big brother! You can't!" cried the former princess, "You p-promised to protect me."

"Don't worry little girl. Everything will be alright," said a voice out of nowhere. Nunnally would have jumped in surprise if she could. She had been too busy worrying over Lelouch that she failed to notice what sounded like a women approach them.

"W-who's there? Please, whoever you are, please save my brother," pleaded Nunnally. The exiled princess hoped with all her being that this mysterious woman wasn't going to bring any harm to her dying brother, but something about her just made Nunnally feel…safe. Her very presence oozed a field of goodness and justice that reassured Nunnally immensely. But there was something else there, pervading the women's aura. It was something odd, something alien.

The voice of the enigmatic woman continued speaking, "Your brother is in good hands. Just relax and we'll get you to safety. And as for who I am…"

"My name is Diziet Sma."

A.N. Well, there you go. And yes, this is a crossover between Sunrise's Code Geass and the Culture series by Iain M. Banks, neither of which I own. I hope you enjoyed my first attempt at creative writing, so please read and review!
