Kael watched the twins, Miyo and Ren, as they slept soundly on the makeshift cots Tom had generously provided in the small adjacent room. Their breathing was even, their small faces finally relaxed after days of apprehension and the recent journey. A faint, intricate shimmer, barely perceptible to even Kael, pulsed around them – a protective weave of Haki, a subtle mending he had performed while they rested, easing the lingering echoes of fear and exhaustion that clung to their nascent life forces.\n\nThe sun, already high above Water 7’s bustling docks, cast long, shifting shadows through the workshop’s open doors. Tom had likely been up for hours, the rhythmic clanging of hammer on wood already a familiar backdrop. It was time. Kael took a deep breath, the salty air filling his lungs, steeling his resolve. He had secured their immediate safety, but true security, and his path to understanding the world and its coming chaos, lay in gaining knowledge, and perhaps, leverage. Tom’s expertise was a gateway.\n\nWith a final glance at the sleeping children, Kael stepped out of the small living quarters and into the main workshop. The scent of sawdust and fresh timber hung heavy in the air, a testament to relentless craftsmanship. Tom, a hulking figure with a wide, kind smile, was already hunched over a partially constructed keel, his brow furrowed in concentration. The raw power of his Haki, not yet refined into a combat form but present in every swing of his hammer, resonated with the very wood he shaped. Kael could see it, a robust, unwavering golden current flowing from Tom’s hands into the timber, imbuing it with resilience.\n\n“Good morning, Tom-san,” Kael greeted, keeping his voice respectful but firm. He wasn’t here to beg.\n\nTom grunted, not looking up immediately. “Morning, Kael. The kids settling in alright?”\n\n“They are, thanks to your generosity.” Kael paused, choosing his words carefully. “I’ve been thinking, watching you work… this craft, shipbuilding, it’s fascinating. I’d like to learn.”\n\nTom finally straightened, a plank of wood held effortlessly in one massive hand. He turned, his eyes, sharp and intelligent despite their weary bags, sizing Kael up. “Learn, eh? Not many come to Water 7 just to learn the trade these days. Most want a quick passage, or a quick buck.” His gaze lingered, a silent assessment.\n\n“I’m not like most,” Kael stated, meeting Tom’s gaze unflinchingly. “I have a deep respect for the art, for creating something that can brave the seas. And I… I have an aptitude for seeing things, understanding how they fit together, how they endure. I believe I could be a good student.” He couldn’t explicitly mention Haki, not yet, but he could hint at his unique perception.\n\nTom chuckled, a booming sound that reverberated through the workshop. “Seeing things, eh? You’ve got a glint in your eye, boy. And you’re not wrong about the enduring part. A ship is a living thing, built with soul.” He set the plank down. “It’s hard work, mind you. Long hours, calloused hands, and a mind for detail. You up for it?”\n\n“More than ready.” Kael’s conviction was absolute. This wasn't just about shipbuilding; it was about understanding the world's structures, its foundations, and the very Haki that intertwined with them.\n\n“Alright then,” Tom said, a wide grin spreading across his face. “Consider yourself an apprentice. First lesson: sweep the damn sawdust. And don’t think you’ll be touching a hammer for a month.”\n\n--- \n\nDays bled into weeks, and weeks into months. Kael’s initial duties were indeed menial: sweeping, hauling timber, sanding planks until his fingers ached, learning the names of every tool, every joint, every type of wood. Yet, he approached each task with an intensity that surprised even Tom. As he swept, he didn't just see dust; he saw the faint Haki residue left by busy hands, the minute vibrations of the floorboards. As he sanded, he didn’t just smooth wood; he perceived the internal Haki flow within the grain, learning its resistance, its strength, its subtle imperfections.\n\nHis unique perception allowed him to grasp the principles of shipbuilding at an astonishing rate. While Tom taught him the practicalities – the angle of a mast, the curvature of a hull, the strength of a rivet – Kael was simultaneously observing the 'Haki weave' of each component. He saw how Tom’s own Haki, infused into the ships he built, gave them their legendary durability. He began to understand that the very ‘soul’ Tom spoke of was, in essence, an intricate application of Haki, consciously or unconsciously woven into the vessel’s design.\n\nTom, despite his gruff exterior, was a patient and thorough teacher. He saw Kael’s innate talent, his quick mind, and his unwavering dedication. Kael, in turn, revered Tom as a master. He learned the physics of buoyancy, the engineering of stability, the art of crafting a ship that could withstand the Grand Line’s fury. He started with simple repairs, then moved on to smaller components, always under Tom’s watchful eye, his hands growing calloused, his muscles gaining strength. His own Haki, previously focused on self-defense and observation, began to subtly influence the materials he worked with, infusing his creations with a nascent resilience.\n\nEvenings were Kael's private lessons. While Tom often toiled late into the night, consumed by the blueprints for a particular ‘fishing ship’ – a vessel Kael knew in his gut was destined for a pirate king – Kael would linger. He’d pretend to clean, to organize tools, but his true purpose was far more clandestine. He would extend his Observation Haki, not merely as an awareness, but as a probing, tracing tendril of energy. He focused not just on Tom’s physical form, but on the complex patterns of thought, the concentrated Haki surrounding the blueprints Tom studied, the mental images Tom projected onto the wood.\n\nAt first, it was fragmented, blurry. Kael picked up on the immense scale, the colossal power, the revolutionary design that pushed the boundaries of what a ship could be. He sensed elements that defied conventional understanding, details that resonated with an ancient, terrifying power. As Tom worked, as his mind delved deeper into the intricate schematics of his commissions, Kael’s Haki weaving became more precise, more invasive. He wasn't just reading thoughts; he was piecing together the Haki signatures of architectural concepts, of entire, complex machines yet to be built.\n\nOver the months, Kael’s subtle probing yielded an unimaginable treasure. He began to discern the distinct Haki pattern of an Ancient Weapon – Pluton, or as he remembered it from his past life, the Battle Franky, later known as Franky's ultimate dream. No, not Franky's dream, but the actual blueprints for *Pluton*, hidden within Tom's deepest memories and likely within the workshop itself, a legacy passed down through generations of Water 7 shipwrights. The sheer destructive potential, woven into its very conceptual Haki, was staggering. It wasn't just a ship; it was a floating fortress capable of leveling islands, a weapon that could reshape the world.\n\n--- \n\nTwo years passed like the relentless turning of the tides. Kael, no longer the uncertain youth who had arrived, now stood taller, his frame lean and strong, his hands scarred but skilled. He moved with a quiet confidence, his eyes sharp, reflecting a depth of knowledge far beyond his years. He had built countless small boats, assisted with larger vessels, and even crafted intricate wooden toys for the now-thriving Miyo and Ren, who considered him an older brother.\n\nHe had mastered every principle Tom had taught him, from the foundational strength of the keel to the delicate balance of the rigging. His Haki weaving, honed by constant application, could now subtly enhance the durability of the wood he worked, shaping it with an almost intuitive understanding. He could detect the slightest structural flaw, mend internal stresses in timber, and envision the completed ship with perfect clarity, almost as if he was weaving its Haki into existence before a single plank was laid.\n\nBut his most significant achievement remained a secret. Through tireless, clandestine Haki observation, Kael had not only pieced together the complete, detailed blueprints of Pluton, the Ancient Weapon, from the fragmented Haki signatures he gleaned from Tom’s work and memory, but he had also understood its very essence. He knew its strengths, its weaknesses, its vulnerabilities, and the specific Haki applications required for its construction and operation. He had, in essence, become a master shipwright, and the silent, secret keeper of one of the world's most terrifying powers. The age of rocks continued to rumble, and Kael, with ancient knowledge now etched into his Haki, was more prepared than ever for its coming storms.
