Margin of Error

0000: Prologue
…​

In my first life, my real life, though I was learning not to call it that, Edinburgh had been different: greyer, grimier, and louder. This Edinburgh gleamed. The trams ran silently on magnetic rails, and the castle had lights installed that adjusted to the weather. Even the rain smelled different: clean, scrubbed of the coal and petrol I remembered but had never breathed in this body.

I sat on my bed, a datapad resting on my knees, its screen casting pale light across my face. Eight years old, or so they told me. Eight years since I had opened my eyes in a crib I did not recognise, in a home that was not mine, wearing a body that responded in ways no infant's should.

Eight years of learning to be someone new while accepting that my former life was gone.

My name is Marcus Cormac Sinclair. It wasn't always.

Before, in the life I remembered as clearly now as the day I'd woken in the body of a babe, I'd been someone else entirely. A man grown, also, interestingly, from Scotland. I shared that link with this new life, but little else. Back then, I had gone to sleep one night, as I always did. The next morning, I woke up as Marcus. One moment there, the next… here.

Unable to speak, I couldn't scream or shout. I couldn't ask about what was happening, where I was, what had become of my former family. By the time I was able to make this form talk, I had realised that this life was mine now. I still didn't accept it truly; the images of what I had once been remained. The grief at who I had left behind, no idea of their fate, lingered.

Those nights I'd cried over what had been, my new parents had attributed it to bad dreams. What else could they think it was? I was a child, one not able to walk or talk, and I cried. No one would expect a child to weep for a former life no one else knew about.

By the time I could walk, by the time I was able to hold something approaching a conversation with my parents, I had made peace with the altered hand that was dealt. Yet I knew this world was different from what I knew. I was in Edinburgh; the city was the same, and yet it wasn't.

On the surface, it was close enough to ignore. Yet the moment one looked at it, it became clear it was different. Technology was more advanced, the air cleaner, and the mood was less constricting than what my former life had felt like.

By the time I could read, I was cataloguing the differences.

And with each passing day, those differences only ever increased.

I'd read the history of this world as best I could, as much as my parents allowed a child to do so. This world had diverged a century before. The beginning of the twenty-first century had been the pivot. Events either didn't occur or happened differently. No 9/11, no COVID, no rise of the fracturing of politics. At least not to the degree that I remembered from that former life.

In their place, the Oil Wars. The shadow conflicts over resources. And then, a revolution in nuclear power, and it was as if someone had flicked a switch: stability, peace, balance.

For a time, all the differences, all the alterations, the fact that it was a century after the point my former life had ended in a night, were the most jarring. There had been years when every new change and shift in the direction of Earth frightened me.

None of that frightened me anymore. What frightened me was what I carried inside.

I looked down at my hands. Small. A child's hands. Exactly as they should be, and yet they didn't feel like they were. I knew I wasn't normal in ways that went beyond the obvious.

I'd noticed it first in how fast I'd picked up things. Then, I'd simply assumed it was memories of my former life carrying into this one. Preschool was easy, too, yet it was more than that. Then, at five, I'd discovered the first hint that something was… off.

I'd caught a cup before consciously registering it was falling. Those around me hadn't reacted to the cup. Not until I put it back on the table. From there, everything was questioned and then tested.

A random scroll I had read in preschool once was remembered clearly. A training piece of music was learned and reproduced after seeing the teacher play it once. The fact that I was faster, stronger, and quicker than those around me.

This body, this mind… they were wrong. Or perhaps it was fairer to say that they were too right, too perfect. Either way, it was dangerous. To me, and to my family.

Downstairs, I could hear my father explaining something to Callum. My younger brother was five and, from everything I'd seen, ordinary. Or at least, not like I was. My mother was in the kitchen; I could hear her movements, could smell the herbs she was using even though I shouldn't. Keira, my older sister, had music playing in her room. It was proven to mute noise from travelling in or out, yet I could track the strings, hear the angst in the track. I could feel the faint, impossible vibrations in the old floor.

This was my family. My family, and yet it wasn't.

Not the one I remembered. They were gone, if they ever existed at all. This family, the Sinclairs, were my new family, Marcus' family. My parents had raised me, my sister had teased and embarrassed me, and my brother looked up to me. They loved me, and I loved them, though it had taken me years to truly accept that the affection wasn't a betrayal of what had come before.

My eyes trailed over the screen of my datapad. The one that contained my secrets.

A gift when I turned eight a few months ago. One I had hardened in ways no eight-year-old should know how to. No network connection, no cloud backup, no outside connection, a pass-string that couldn't be broken without dedicated software.

The entirety of my understanding of a possible truth.

Inside were my observations, catalogued with the precision that came too easily: timeline divergences, technological anachronisms, political movements that shouldn't exist. The file marked 'ANOMALIES' grew faster than the others. Yesterday, I'd added a note about the Mars exploration initiative: The funding suggested that they expected to find something beyond just rocks and dead volcanoes. What that was, I didn't know, though I had theories. None of those was comforting.

A second childhood stretched before me, years of growth and education ahead, and I refused to waste them. I refused to live a meek, simple life. This body, my memories, were given to me for a purpose. The feeling that something existed at the edge of my thoughts, understanding or knowledge that would help explain this new life grew stronger with each passing day.

I didn't know why I was here, what purpose this existence served, if there even was any. Perhaps there was none. Perhaps I was simply cosmic debris, swept from one existence to another by forces beyond comprehension.

My fingers tightened around the pad's edges. I didn't believe that. I couldn't.

The flickers of something in my head were proof. Knowledge that I shouldn't have, ideas that didn't quite align with how things in this world worked. Hints that, while everything was how it should be, that wasn't the case. As if there was a puzzle of galactic proportions in my head, yet I had no idea what it was meant to be.

Each time I learnt something new, each time I pushed for knowledge of this world, another piece was revealed. Another clue, however inconsequential, was gained. I had to know more; I would know more. I would learn the science of this world, use it to unlock what was trapped beyond my conscious thought.

It was the only path I had that offered any hope of answers.

The rain continued its patient assault on the window. I watched it fall, this child who was not a child, and made myself a promise.

Whatever had brought me here, whatever waited in the years ahead — I would be ready. I would build carefully, hide what needed hiding, and when the moment came that demanded I act...

I would not waste my second chance.

The letter sat on the kitchen table between us, cream-coloured paper bearing the crest of Caledonian Academy. My mother's tea had gone cold. My father hadn't touched his. I found amusement in their reactions and the fact that the Academy had sent a letter. Anachronistic, unpopular with many, and yet a sign of their standing and brand.

"They don't usually offer places to children your age," my father said, his engineer's mind working through the implications. "The standard intake is twelve, sometimes eleven for exceptional cases. You're not even ten."

I knew this. I had researched Caledonian extensively over the past year, alongside other such academies and institutes. I'd mapped their alumni networks, their academic reputations, their connections to key universities and industries: paths that would help define my path forward once I left their halls. Caledonian wasn't the most elite, the most widely known, nor the richest. It was, however, the most efficient for me.

Close to home, less rigorous physical checks and expectations, and access to several cutting-edge STEM programs. The best overall package, and one that, if I applied for, my parents could afford without damaging their lives or limiting the development of my siblings.

"Marcus." My mother's voice drew my focus, her tone carrying a hint of suspicion. "Did you apply for this?"

I shook my head. "No." The truth, though, only because I hadn't taken the final step. Draft letters had been written, stored on my air-gapped, secure datapad. None had been sent. Drawing attention to myself when there were so many unanswered questions about this world was a step too far. "My teachers must have submitted something. Mrs Patterson mentioned a programme for advanced students last term."

A half-truth. What I failed to mention was that I had guided those conversations, asking questions that reinforced that my displays in class weren't by chance. That I had the capability to go further, faster than those around me. My interactions and words showed enough to intrigue my teachers, but never enough to alarm.

It was exhausting, this constant need to calibrate myself. Every test was answered with small, deliberate errors scattered among the correct responses. Every class discussion was balanced between insight and age-appropriate ignorance. Two years of walking a line so fine it sometimes felt like it would cut me in half. Caledonian, and others like it, offered a chance to remove the limits I placed on myself, at least in part.

My parents exchanged a look; one I had learned to read. They were concerned yet proud. Uncertainty over whether they should nurture my gifts and push me, or protect them by allowing me to develop without impetus. They had noticed I was different, special. How could they not? But they attributed it to intelligence, to an old soul, to the luck of the genetic lottery brought forth by laws offering boosts for newborns. They didn't know the half of it.

They couldn't.

"It's a significant opportunity," my father said slowly. "The resources, the instruction, the connections you'd make. But you'd be years younger than your classmates. That comes with challenges."

Mum's hand was warm. Warm in the way that hands always feel when you're cold. I wanted to pull away and lean in at the same time. That's what made it so hard; this love felt real. It was real. Yet, letting it flow around me felt like a betrayal. Eight years ago, different hands had held mine. I couldn't remember the faces anymore, not clearly, but I remembered being loved before.

"I want to go," I said, genuine emotion colouring my voice; the eagerness of youth was displayed on this rare occasion.

It wasn't entirely a performance. The Academy meant access to laboratories, to libraries, to minds that might help me unlock the fragments of knowledge lodged behind my conscious thoughts. Every equation I learned seemed to shake something loose, to illuminate another corner of whatever vast understanding had been placed inside me. The chance to push a little faster and further, to learn more of what was locked in my mind, was one I couldn't afford to miss.

I needed that knowledge. With each passing month, the feeling grew that I was preparing for something, building toward a purpose I couldn't yet name. A reason why I was here.

There had to be a reason.

My mother reached across the table and took my hand. Her skin was warm, her grip gentle. "You're sure? Once you're there, you can't simply come home if it gets difficult."

I nodded. "I'm sure." I met her eyes, and for just a moment, let my guard slip. Not in full, never that, but something honest and earnest. "I need to learn, Mum. Everything I can. I don't know why yet, but I need to learn more to push myself."

She studied my face, and I saw something flicker in her expression. Recognition, perhaps, of the weight behind my words. Fiona Sinclair had spent her career navigating the gap between policy and implementation, reading the subtext beneath official statements. She knew when someone was holding back.

But she also knew when to trust.

"Alright." She squeezed my hand once before releasing it. "We'll visit next week. See the facilities, meet the staff. If it still feels right after that..."

"It will," I finished, certain now that the path was before me.

I pulled the letter to me, enjoying the feel of the paper between my fingertips. One tip traced the Academy's crest. A lion rampant, navy blue with claws extended, ready to strike. Fitting, I thought with amusement, for the path I was choosing.

In my room, the datapad waited with its encrypted files. Tomorrow, I would update my plans and adjust my timelines. The Academy accelerated everything by two years, opening doors I hadn't expected to reach so soon. That brought danger: the chance to draw unwanted attention I couldn't yet counter. However, the chance to learn more about this world, to see how it worked, and to understand the systems others failed to realise existed in society. Those were things I couldn't fail to grasp once they were presented to me.

I would have to be careful. Older students would watch me; teachers would scrutinise me. The child genius, some would call me. A spoilt brat, others would say. Both descriptions were right, and yet neither was. The truth was far more than anyone would realise, and because of that, I had to be cautious.

I could stand out, yes, but never too much. Never go too far too fast. Doing so led to more questions, the kind that often came with examinations and tests; the type of moments that led to discoveries I could not afford.

Yet the opportunity merited the risk. It had to be.

I knew there was a reason I was here, that I was given this second life. The knowledge in my head, the hints of paths that didn't seem right when compared to what I knew of this world, had to serve a purpose.

I wasn't arrogant enough to think I could change the world, that I could save it from some unseen disaster. Yet, if such an event lay in the future, I would meet it prepared.

The Academy was simply the next step.

I was still nine years old, but I had a future to build.

​

---***---​

The gates of Caledonian Academy loomed before me, wrought iron crowned with that same rampant lion I'd seen on the letter. Beyond those gates, stone buildings sprawled across manicured grounds, their architecture a deliberate link to tradition, altered by the various displays of modernity. Old enough to impress, new enough to function.

Around me, other students streamed through the entrance, everyone older and taller than me. I saw many looking around in wonder, talking animatedly with others. First-years, lingering, taking in the sights, carrying their bags. A handful seemed nervous, likely due to the uncertainty of leaving home for the first time.

I was lucky. Caledonian was close enough to my home that I could head back each weekend. I would, my mother insisted. Many others, it seemed, were not as fortunate, no doubt having already seen their bags taken to the dorms at the northern end of the campus.

As I moved towards the gates, I felt the eyes of the other students, new and returning, on me. The looks came in waves, all carrying the same three emotions, or variants of them: curiosity, confusion, and amusement. I was a child among adolescents, barely reaching their chests, with my uniform crisp and new and slightly too large despite the tailoring. My parents had insisted on room to grow. They weren't wrong, though I suspected the growth would come faster than they anticipated.

Entering the grounds, I caught fragments of conversations.

"Why's a kid here?" someone asked, not quite quietly enough that I couldn't hear them.

"Fresh meat," another muttered, hints of amusement and possibly something darker in their tone.

"Whose little brother is that?"

I ignored them all, the comments washing over me. They weren't wrong to stare. In their place, I would have done the same, though with better grace. A nine-year-old entering secondary school was unusual enough to warrant attention. I needed to manage that attention, cultivate it to suit my purpose. Too much, and questions followed. Too little, and I became invisible, unable to build the connections that would matter in the years ahead.

Six years was how long I was meant to be here. Six years of classes, laboratories, and libraries. Six years to learn, grow, and unlock more of whatever knowledge lay dormant inside my mind. The fragments had seemed easier to discover during the last few months of preparing to enter Caledonian. Not enough to reveal secrets of use, but enough to show they were there just out of reach. Teasing challenges to unravel and use, at least if I could do so safely.

I had these six years to find those worth my time, to build connections with them as I built my foundation. Academic credentials were a given, but the right relationships could be worth more. Yearmates who would become colleagues, teachers who might open the doors to mentors, potentially even rivals who would sharpen me against their edges. The social architecture of a life took time to construct, and I intended to use every moment.

A group of older boys passed, their uniforms bearing the pins of third-years. One glanced down at me with the casual dismissal of someone who had already categorised and discarded what he saw. An irrelevant child beneath their notice.

Good.

Let them underestimate me. Let them see only the small frame and young face. By the time they realised their error, I would be too established to dismiss and too ingrained for them to ignore. That was the game I had chosen to play: the patience of youth that hid ambition behind earnestness.

I adjusted my bag on my shoulder and walked through the gates.

The Academy awaited. My future awaited. And somewhere, in the locked corners of my mind, answers awaited, too.

I intended to find them all.

A/N: Welcome to my newest story. Like the others, this will be a slow burn with world-building involved over a long ride.

In their place, the Oil Wars. The shadow conflicts over resources. And then, a revolution in nuclear power, and it was as if someone had flicked a switch: stability, peace, balance.

Click to shrink...

One can hope.

Ironically, we're about to get that revolution, when we should have had it 50 years ago, because NOW the elites want it for their data centers, rather than wanting to deny us as punishment.
