The following morning dawned beneath a clear sky, with a cool breeze carrying the characteristic scent of the kingdom's capital, mixed with the bustle of the central streets where commerce and specialized guilds concentrated their activities. I left the mansion in the attentive care of Vespera, Eara, Rai'kanna, Lyannis, Liriel, and her assistant, as my mission for the day required a direct visit to the headquarters of the Royal Builders' and Engineering Guild. It was an ancient institution, famous for erecting the walls that protected the city against invasions and designing palaces that defied time. Walking along those cobblestone-paved avenues gave me a distinct sense of contrast with the dark and unpredictable corridors of the Tower; however, the responsibility weighing on my shoulders was no less significant. I needed to ensure that our underground infrastructure would be indestructible, and for that, I would accept nothing less than the best service available throughout the entire human territory.
As I crossed the imposing noblewood doors of the engineering guild, I was immediately greeted by the attendant on duty, who instantly recognized my crest and reputation. It took no more than a few minutes before I was escorted to the main office, a spacious room filled with topographical maps, scale models of fortifications, and stacks of ancient scrolls containing complex structural calculations. Behind a solid oak desk sat the Chief Builder, an elderly man with a neatly trimmed white beard that reflected military discipline and shrewd eyes that seemed capable of calculating the strength of any material at a single glance. He raised his head, adjusted the prescription glasses resting on the tip of his nose, and looked at me with a mixture of institutional respect and genuine curiosity, knowing perfectly well that the hero Takumi would not visit a technical guild without having a monumental purpose in mind.
"Welcome to our headquarters, Master Takumi," the old master builder greeted me in a firm voice, indicating the upholstered chair in front of his desk. "I've heard many rumors about your exploits on the upper floors of the Tower and on the battlefronts against the dark forces, but I confess I didn't expect to see you seeking our masonry and heavy engineering services so soon. Tell me, what brings an elite adventurer of your stature to our humble builders' organization?" The professional's direct and polite approach pleased me; I preferred straightforward negotiations in which each party understood exactly the weight of the demand and the capacity to deliver. I leaned slightly forward, resting my arms on my knees, and decided to explain the real problem that had brought me there on that sunny morning.
"My current residence, the mansion we acquired in the noble district, has become too small for the scale of our resources," I began calmly, observing the old builder's attentive expression. "The main vault in the house is completely filled with spoils and wealth accumulated during our recent expeditions. I don't want just a superficial expansion; I need a large-scale underground construction, a truly fortified and secure complex beneath the mansion's foundations, with advanced magical insulation, retaining walls reinforced with special metal alloys, and enough space to store massive quantities of treasures and rare materials in complete security against any kind of arcane or physical invasion." The builder raised a graying eyebrow, clearly surprised by the audacity of the project scope I had just outlined in a few words.
The man slowly rose from his chair, walked over to a bookshelf at the back of the room, and pulled out a bulky scroll, unrolling it across the desk to reveal a generic structural diagram of underground foundations. He crossed his arms and looked at me with renewed seriousness before responding. "Master Takumi, do you realize what you're asking for? Excavating and fortifying an underground complex beneath an existing structure requires extremely complex engineering calculations to avoid compromising the stability of the soil and the mansion itself on the surface. Furthermore, the materials required to guarantee insulation against high-density magic are rare, expensive, and require special permits from the Crown to be transported in large quantities through the city." He paused for a moment, measuring my reactions with surgical precision before delivering the preliminary financial verdict for that monumental project.
"To carry out a project of this scale, with the technical quality, multilayered security, and speed you will undoubtedly demand, the total cost will be fifty thousand gold coins," the Chief Builder declared without hesitation, watching closely to see whether the astronomical amount would make me back down or reconsider my plans. "To be perfectly frank with you, the only client in the entire kingdom who has commissioned an underground structure with similar specifications in the past was the Royal Family itself, for the treasury of the fortified palace. This is no ordinary construction project, and the price reflects the risk, the specialized labor, and the exclusive magical materials we will have to use from the underground levels all the way to the surface." The revelation that the cost was equivalent to the operating budget of small cities did not frighten me, but it helped me grasp the magnitude of the undertaking I was about to finance.
I remained silent for a few seconds, pondering the impact of that colossal expense on our current financial reserves, although I knew perfectly well that the capital accumulated in the magical storage bag exceeded that amount many times over. I looked directly into the old builder's eyes, conveying an unwavering calm that made him realize the quoted price was not a real obstacle for our guild. "The amount is high, I admit, but the security and infrastructure of my operational base are not areas where I'm willing to cut costs," I replied firmly, breaking the suspense hanging over the meeting room. "If the required standard is the same one reserved for the royal treasury, then that is exactly the level of excellence I'm hiring you to provide here and now. I accept the terms and the stated price, provided that construction begins immediately and is completed within a maximum of one week."
The Chief Builder's reaction was one of undisguised astonishment, followed by a smile of deep professional respect. He was not accustomed to dealing with clients who approved a budget of that magnitude so quickly and naturally, without even attempting to negotiate a single coin off the price. "You adventurers of the new generation really operate on another scale," he commented, nodding in approval as he pulled out a magical contract for me to sign with my personal mana seal. "It's a deal, Master Takumi. My team of engineers and construction mages is already standing by. We will begin the excavations and the containment runes early tomorrow morning. Your mansion will undergo the most impressive transformation this capital has seen in decades."
I signed the document with a firm stroke, feeling the contract's magical energy bind the agreement to our mutual terms of commitment and punctuality. We spoke for a few more minutes about the logistical details of moving the team into the mansion, coordinating schedules to minimize the disruption to its residents, although the group was already aware of the need to vacate the premises temporarily. The feeling of having fulfilled my duty and actively resolved the guild's structural problems brought me a renewed wave of personal satisfaction. That investment of fifty thousand gold coins was not a wasted expense, but rather the solid foundation upon which we would build our future and the nonnegotiable security of all the wealth we had earned through blood, sweat, and memorable victories on the kingdom's battlefronts.
I bid the Chief Builder farewell courteously, tucked my copy of the official contract into the pockets of my tunic, and left the engineering guild's headquarters with firm steps toward the outside, where the afternoon light was beginning to turn the facades of the neighboring buildings golden. The sun shone brightly in the clear sky, seeming to bless the beginning of this new administrative phase in our journey. As I walked back through the capital's busy streets, my mind was already calculating the next practical steps: informing the women at the mansion about the immediate start of construction the following day, organizing our temporary move to the traditional inn that had marked the beginning of our journey, and preparing myself for the days of rest, festivals, and unexpected turns awaiting us in the kingdom's central square over the coming days.
The transition between the brutality of combat in the Tower and the strategic bureaucracy of resource management required mental flexibility, a skill I had been constantly honing ever since I assumed absolute leadership of the guild. Every decision made that day reinforced my certainty that our rise depended not only on the group's members' sheer physical strength, but also on logistical intelligence, the ability to anticipate financial risks, and the unbreakable unity we maintained in the face of any adversity. The mansion would soon become unrecognizable, boasting an impenetrable underground vault in its depths, worthy of the legends we were beginning to write in the pages of this world's history. With the plan proceeding perfectly, I quickened my pace on the way home, eager to share the details of the successful negotiation with my companions and begin preparations for our brief stay in the city.
