Author's Note: So I found a 30 day AU challenge on tumblr and decided to focus on Code Geass. That being said, please note that these are little snippets of stories and will probably not be continued. If you want to take an idea and run with it, however, just credit me with the original idea and shoot me a message when you've started posting. Also, please not that there are multiple pairings within this challenge, not just Suzalulu. Finally, the chapter titles are the prompts for the fic.

A Multiple of Possibilities

One last quick note before we start. This takes place in the same universe as my other Code Geass/Hogwarts crossover Between Professors.

Chapter One: Hogwarts

It always amazed Lelouch to watch Suzaku perform magic at the shrine, mostly because he was always afraid that Suzaku would get caught.

Back in England, students weren't allowed to use magic outside of Hogwarts. Lelouch had heard horrible rumors about those students who did, even though he knew that they just got expelled. That still didn't explain the mysterious catches of luggage that Lelouch had found at the end of his second year.

He pulled his knees up, watching as Suzaku carefully circled the area around the tree. Then again, magic was different in Japan. They had often compared spells, Lelouch trading the ones he learned for some of Suzaku's spells, like the one that kept his fire burning no matter what. In the damp rooms of the Slytherin dorms, Lelouch was more than willing to cast the spell, even after he found out that he was invoking a fire demon to do his bidding every time he cast it. The comfort was worth it.

The Japanese spells weren't all wand waving and precise words, although Lelouch knew of a few that Suzaku was still struggling with. Most of it was through simple objects, pieces of paper with the spells already written down and through careful rituals. Compared to the magic that he was taught at Hogwarts, it looked archaic. Lelouch had learned that wizards in Britain had once used the same lengthy rituals to carry out their spells, but magic had become streamlined since then. If any of his friends from Hogwarts had seen Suzaku working his magic they would have laughed; thinking that Suzaku was a squib who needed the extra help or a muggle who was faking it. That was one of the reasons that Lelouch rarely told his year mates where he went over the summers, because then he would have to explain why he enjoyed watching Suzaku work magic so much.

Lelouch was distracted by his thoughts by a rustle in the tree. By the way that Suzaku had stopped his friend already knew that something was there. Lelouch pulled his legs closer to his body, ready to run if Suzaku shouted at him. He had ignored Suzaku's warning once and had regretted it when the oni had come charging at him. Lelouch still had the scar on his side to prove it.

Suzaku didn't seem to be worried at all. He just took a step back, dragging the stick in front of him to complete the complex design that he had been drawing in the dirt for nearly ten minutes. Lelouch had to marvel at Suzaku's concentration, considering his friend could barely sit still long enough to get through some of his tutor's lectures. Still, when it came to his duty, Suzaku was nothing but attentive. When his apprenticeship was over, he would be in charge of watching the area around the Kururugi house and shrine, just like his mother was doing. In that case, Lelouch wasn't too surprised about Suzaku taking his job completely seriously.

There was a rustle from the tree, Lelouch getting a brief glimpse of a human face before the thing surged out of the top of the tree. Lelouch jumped to his feet when it turned into a fireball, ducking around the rock he had been sitting on for cover. It was the typical maneuver that Suzaku had ordered him to take whenever something appeared. These weren't the carefully secured creatures that he had seen in Defense Against the Dark Arts class, or from afar as the third years had trooped off to Care of Magical Creatures. This was something completely wild, and dangerous if Lelouch remembered the circle that Suzaku had drawn correctly. Wild, dangerous and screaming, far too much to allow a thirteen year old boy to handle.

But that was back in England.

Suzaku stood his ground as the thing came hurtling at him. Lelouch thought he heard the fireball cackle just before it swooped into the circle. The creature probably thought that Suzaku made an easy target, but it was brought to a stop by the circle. The fireball turned in place as Suzaku clapped his hands together and ducked his head.

The invocation was too fast and too quiet for Lelouch to catch all of it, but he knew the just of it. Apparently, there were different ones that Suzaku had memorized, but they all essentially said the same thing. Each named the creature, bound it to the power in the circle and then either sent it into an object or banished it away. Lelouch had never been too clear on where the creatures went, and Suzaku would never tell him. Apparently it was a trade secret.

The fireball gave a high pitched squeal before being sucked violently into the small jar that Suzaku had placed in the center of the circle. Still chanting, Suzaku followed, stepping into the circle to cram the top of the jar back on. There was a moment of high pressure, like the moment before a thunderstorm, before Suzaku banished the magic back into the earth.

He knelt by the jar, resting a hand on it for a moment before nodding. Suzaku sat back with a sigh, glancing over at Lelouch. After a moment, he grinned. "You can come out now."

"I knew that." Lelouch stormed out from his hiding place, carefully wiping the dirt from his shorts. "I just wanted to wait, to make you feel better."

Suzaku stared at him quizzically for a second before shrugging. Lelouch took that as an invitation to join him, careful not to mar the circle as he stepped in. Sometimes they had to wait a while just to make sure that the creature was well and truly caught or for the magic to dissipate. Lelouch remembered Suzaku being lectured on his carelessness once, and he had never heard his friend lectured again after that.

He pulled out his wand, tempted to poke the jar, but he didn't. Instead, he twirled the wand in his fingers, watching Suzaku's eyes follow it. To his knowledge, Japanese wizards didn't rely on wands. He had seen a few, but they seemed to be something that was given to wizards when they had finished their training. Suzaku was probably a bit jealous of his wand, something that Lelouch thought was silly. Suzaku could work magic without a wand already; Lelouch still had no idea how to do that on his own.

Lelouch let his wand drop to his side, out of Suzaku's sight. Instead, he leaned forward and stared at the jar. "What was that?"

"Tsurube-otoshi. It was bothering the neighborhood for a while." Suzaku shrugged one shoulder and looked up at the sky. "It was actually harder to catch than I thought it would be."

"What can you use it for?"

Suzaku looked startled by his question. "Uh, you could use its power for protection spells, I guess, or bind it to serve you. I don't know, I usually don't think about these things."

"You just hand it to your mother."

Suzaku nodded and pulled his knees toward his chest. "Yes. I'm hoping this will be enough to impress father, because he's promised me something special for my next birthday if I prove myself ready."

Lelouch resisted the urge to snort. He would never understand Suzaku's need to earn his father's attention, especially when the man had never cared for Suzaku before. Genbu was just happy that his son was proving to be powerful, something that Lelouch wanted the hurt the man for. He bet Genbu didn't even know how kind Suzaku could be, his son's moments of great insight that even startled Lelouch. All he cared about was having a son that wouldn't embarrass him in the wizarding community.

As if Suzaku guessed what Lelouch was thinking, he reached over to poke Lelouch's shoulder. "I'm free after this, what do you want to do?"

"I don't know." Lelouch shrugged. "But I don't want to race you back."

"I'll go easy on you this time."

Lelouch just glared at Suzaku, relieved that his friend laughed. But he wasn't going to back down on the race. Suzaku always won, even when Lelouch tried every trick he knew to slow Suzaku down. He would have suspected Suzaku of using magic, but his friend was too earnest for that.

He leaned back on his hands, fully expecting Suzaku to make another suggestion for their next activity. He was surprised when Suzaku just copied his pose, staring down at the jar in the middle of the circle. "How many days until you go back?"

Lelouch bit his lip, looking anywhere but Suzaku. "Five."

Suzaku took the news with a stoic nod. His friend was silent for a while, Lelouch almost ready to agree to another race when Suzaku looked up at him with a smile. "Just remember to write."

"O-of course I will." Lelouch stumbled through the quick change in his friend's mood, not sure what to think of the sudden levity to Suzaku. "Someone has to make sure you don't kill yourself."

"I know what I'm doing, Lelouch."

Lelouch looked back at the jar in the center of the circle, very willing to admit that to himself. Suzaku was on par with some of the forth years that Lelouch had seen at Hogwarts, at least in this. In other matters, Suzaku was about on the same level as a second year. Lelouch couldn't wait until he was allowed to use magic outside of school, just so he could challenge Suzaku to a wizard's duel. He was sure that he would get a better gauge on his friend then.

He stood up abruptly, wiping the dirt from his legs. "Is that done yet?"

Suzaku reached out and tapped the jar, ignoring the way that Lelouch winced at the sound. He tipped his head to study the pot for a moment before nodding. "Should be?"

He scooped up the jar and began rubbing out the circle, Lelouch helping on his end. When it was nothing more than a patch of disturbed dirt, Suzaku tucked the jar under his arm. Lelouch hurried to his friend's side, not saying a word as Suzaku bumped their shoulders together. If anything, he leaned into the touch, because he had five more days.

Five more days in Japan, pretending it was just like those beautiful summer days when the entire world had been in fear. Of course, he had been too young to remember Lord Voldemort, he had been having too much fun with Suzaku once they had gotten over their differences. Five more days until he went back to school and pushed himself through his third year.

He would be able to write to Suzaku, but it wasn't quite the same. Lelouch wanted all of his friends to be at Hogwarts with him, because it was fun there. At Hogwarts, Suzaku wouldn't have to keep putting himself in danger just to prove himself to his father. Genbu would have to be proud of his son if Suzaku won all of the awards that Lelouch knew he could.

But he didn't say any of that to Suzaku. He just let their shoulders bump against each other as they trudged down the dusty road.
