Inside the magnificent dome of the Saint Pendragon Cathedral in Gamascus, Karl August stared upward at the spiraling artwork adorning the vaulted ceiling. The fresco depicted the life of Kara the Great rendered in brilliant colors that still held their vibrancy despite centuries of candle smoke and incense.
Golden light filtered through stained glass windows and cast kaleidoscopic patterns across marble floors polished to a mirror shine. The cathedral was the crown jewel of Gamascus, capital of the Dalion Empire, a monument to both divine faith and imperial power.
Karl exhaled slowly, his breath misting faintly in the cool cathedral air. It had been 2 months since he'd woken up in this body, 2 months since his consciousness had been violently transplanted into whatever the hell this world was.
An alternate Earth clearly, but not the Earth he knew. Europe didn't exist here and neither did Asia or the Americas, at least not with those names or in those configurations. The entire geography was different with continents rearranged and landmasses he'd never seen on any map.
Different kingdoms, different empires, different cultures entirely. The Dalion Empire dominated the center of the Harshan Continent as a sprawling superpower that controlled multiple vassal kingdoms through a combination of military might, economic leverage, and political marriages.
From what Karl had pieced together from this body's memories and his own observations, this world was in the early stages of what he'd call the 19th century. Technology-wise they were firmly in the flintlock era with smoothbore muskets, black powder, and spark ignition firing mechanisms. No percussion caps yet, no rifling in standard infantry weapons, and definitely no breech-loading systems.
Militarily and industrially they were somewhere around the Napoleonic period, maybe a bit earlier.
He still didn't know the full extent of this world's geography. The maps he'd seen in his family's estate library showed the Harshan Continent and parts of neighboring landmasses, but there were vast blank spaces marked as unexplored or uncharted waters. For all he knew this planet was larger than Earth with continents spread across oceans he'd never heard of.
The good news, if he could call it that, was his position. He wasn't some peasant or low-ranking soldier. He was Karl August von Atticus, heir to the von Atticus house and one of the most powerful industrial families in the empire.
The Atticus family had built their fortune on arms manufacturing, specifically flintlock firearms. They controlled the largest gunworks in the empire and supplied muskets, pistols, and artillery pieces to the imperial army and allied kingdoms alike.
The family's rise had come through shrewd business sense and unwavering loyalty to the ruling emperor. In return for that loyalty the von Atticus house had received imperial charters, tax exemptions, exclusive contracts, and land grants. They'd turned those advantages into a manufacturing empire.
Firearms rolled off Atticus production lines by the thousands and each one was stamped with the family crest of a steel eagle clutching a flintlock rifle in its talons.
Karl's mother, Maria Theresa von Atticus, had brought even more wealth into the family through her own bloodline. She was the heir of the von Galion house, an ancient merchant family that controlled sprawling trade networks across the Carsa Minor.
The Carsa Minor was a strategic region of coastal cities and vital shipping lanes. Between firearms manufacturing and trade monopolies the Atticus family was obscenely wealthy, politically connected, and militarily indispensable.
Fortunately for Karl the transition into this body had been surprisingly smooth. The moment his consciousness had settled the language had clicked into place. He could speak, read, and write fluently in what they called Imperial Common, a language that sounded vaguely Germanic with Latin influences.
The cultural knowledge had come with the body's memories as well, including social hierarchies, etiquette, religious customs, and political factions. It was like inheriting a complete education alongside the physical form.
He was here in the cathedral today because his mother had requested his company. Maria Theresa von Atticus was a devout woman, not fanatically so, but she made regular visits to Saint Pendragon Cathedral to offer prayers and make donations. As the eldest son and heir Karl was expected to accompany her on these visits while projecting the family's piety and maintaining their image in high society.
Karl glanced around the cathedral's interior. The place was enormous and could easily hold several thousand worshippers. Rows of wooden pews stretched toward the altar where a massive golden icon of Saint Pendragon stood with his sword raised and a dragon coiled at his feet.
The iconography here blended Christian symbolism with local mythology. Saint Pendragon was supposedly a holy warrior who'd slain a great serpent terrorizing the early empire, though whether that was historical fact or religious allegory Karl had no idea.
Clergy moved through the aisles in flowing robes. Some tended to worshippers while others lit candles or prepared for the next service. The air smelled of beeswax, frankincense, and old stone. Whispered prayers echoed softly off the vaulted ceiling.
Karl's mother knelt at one of the side chapels with her head bowed and hands clasped in prayer. Maria Theresa was in her early 40s, a striking woman with dark blonde hair pinned elegantly beneath a lace veil. She wore a deep blue gown trimmed with silver thread that was expensive but tasteful and projected wealth without ostentation.
Her face bore the refined features of old nobility with high cheekbones, sharp eyes, and a composed expression that rarely betrayed emotion.
Karl stood a respectful distance behind her with his hands clasped behind his back and played the role of dutiful son. Internally his mind was racing.
He wasn't devoted to any church. The only reason he was here was for his mother and to see the cathedral itself. Unfortunately, Saint Pendragon was restricted to nobles only. The official explanation was to "maintain order and preserve the sanctity of this sacred space."
What a joke. Control the access, control who gets to claim divine favor. Nothing particularly sacred about that.
Still, since he was here accompanying his mother, he might as well make use of the time. He quietly excused himself and made his way up the stone staircase leading to the upper gallery, a balcony that circled the cathedral's interior and offered a commanding view of the nave below.
From this vantage point, he could observe the entire space, the layout, the flow of people, the architectural details.
As he leaned against the marble balustrade and gazed down at the worshippers below, his thoughts drifted to his situation in this world.
At first, he'd been content. Rich family, financial security, exemption from military conscription that would've gotten him killed if he'd been born some commoner conscript. Good food, well, mostly good. He'd had to make a few modifications to the menu, but the quality of ingredients was solid.
The Atticus family ate well, fresh meats, imported spices, fine wines, baked goods from their own kitchens.
But there was one thing he couldn't ignore, the hygiene. Or rather, the complete lack of it.
Germ theory didn't exist in this world. People had no concept of microorganisms, no understanding of how disease actually spread. They still believed in miasma, bad air, or divine punishment as the causes of illness.
The result was filth. Streets ran with sewage in the poorer districts. Kitchens were breeding grounds for contamination. People handled food with unwashed hands, stored meat improperly, drank from questionable water sources.
The Atticus estate wasn't as bad as the common areas of the city, thank god, but coming from a modern world, Karl's standards were astronomically higher. The first week after his transmigration, he'd nearly gotten food poisoning from a meal prepared by kitchen staff who didn't understand cross-contamination.
He'd refused to eat after that until he could personally inspect the kitchens. His parents had been confused at first, then concerned. Why was their son suddenly so particular about food preparation? Why was he demanding that servants wash their hands before cooking? Why was he insisting on regular baths, not just the occasional wash?
But Karl had been firm. He'd started instructing the household staff on proper food handling. Wash your hands with soap and hot water before touching ingredients. Keep raw meat separate from vegetables. Cook food thoroughly. Boil drinking water if the source was questionable. Clean surfaces and utensils between uses. Take regular baths, at least 3 times a week, more if possible.
The servants had been skeptical, even resistant at first. This was strange, foreign behavior from the young master. But Karl had the authority of the heir, and more importantly, he'd framed it as maintaining the family's health and reputation. Sick servants couldn't work. Contaminated food could kill a noble just as easily as a peasant.
Gradually, the changes took hold. The estate's kitchens became cleaner. Illness among the staff dropped noticeably. Even his parents, initially baffled by his obsession with cleanliness, started adopting the habits themselves.
Maria Theresa now bathed 4 times a week and insisted on fresh linens regularly.
It wasn't perfect. The city outside the estate walls was still a cesspool. But within the Atticus household, Karl had managed to implement basic sanitation practices that would save lives, even if people didn't fully understand why.
Standing in the cathedral's upper gallery, Karl allowed himself a small, satisfied smile. Small victories. That's how you changed a world. Not with grand pronouncements or revolutionary declarations, but with incremental improvements that people could see and feel.
Hygiene was step 1. Next would come the family business.
He turned his gaze toward the stained glass windows, watching colored light play across the stone columns. Flintlock firearms. That's where the Atticus fortune came from, and that's where Karl would make his next move.
The designs currently in production were serviceable but outdated by his standards. Smoothbore barrels, inefficient powder charges, unreliable spark ignition in wet conditions.
He could fix all of that. Rifling would improve accuracy dramatically. Percussion caps would make the firing mechanism far more reliable. Better metallurgy would allow for stronger barrels that could handle higher pressures.
And those were just the immediate upgrades. Further down the line, he could introduce breech-loading mechanisms, metallic cartridges, even early repeating firearms.
But he'd have to be careful. Too much innovation too fast would raise questions. How does a 20-year-old nobleman suddenly know advanced engineering principles? Why is he redesigning weapons that have worked for decades? Rival arms manufacturers, foreign intelligence agents, even the imperial court might get suspicious.
No, he'd have to introduce changes gradually. Frame them as "inspirations" or "experiments." Test prototypes quietly. Build a reputation as a skilled innovator rather than appearing out of nowhere with impossibly advanced knowledge.
His mother's voice echoed faintly from below, finishing her prayers. Karl pushed off from the balustrade and made his way back down the stairs, his mind already working through design schematics for a rifled musket barrel.
2 months in this world, and he was just getting started.
