The station was not merely a cargo pavilion; it was a grand display of the aesthetic fusion between the two nations. Szayelaporro designed the structure in reinforced white marble, with platforms wide enough to support the weight of ten simultaneous convoys. Meanwhile, Vesta and the artisans of Tempest added details in runic wood and gardens that purified the air, heavy with the physical exertion of the workers.
The inauguration attracted races that, until then, had observed the alliance with caution. Elves from the Sarion Dynasty, independent merchants from the Western Nations, and even Lizardmen tribes from the swamplands approached to witness the mechanical marvel. In the center of the station, a statue of Sirzechs and Rimuru shaking hands symbolized the new order.
However, the Alabaster Outpost brought a challenge that neither Orc strength nor steel rails could solve alone: Conflict Management. With so many different races in a confined space, disputes over exchange rates and boarding priorities began to flare up.
Grayfia, supervising the site, realized the station needed an immediate management system.
"Lord Sirzechs," she said, watching a dwarven merchant argue with a Sarion scout, "the economy flows perfectly, but social friction is a variable Szayelaporro failed to include in his calculations. This outpost is now the most important location in Jura, but also the most vulnerable."
Sirzechs, accompanied by Valerius, walked the platforms. He saw the need to transform this place into an absolute safe haven. Under his command, Szayelaporro installed the "Intent Weighing Posts"—marble portals that utilized data analysis to detect hidden weapons or hostile magicules before any individual could enter the station.
The Alabaster Outpost quickly became the city that never sleeps. By day, the sound of Orc hammers adjusting axles and the voices of traders from across the world created a symphony of progress. By night, the station glowed with Avalon's crystal lamps, serving as a beacon of civilization in the heart of the wilderness.
The first major official transaction at the station was the sale of Tempest silk for Avalon Ducats, which were then used to purchase Dwargon steel. The economic cycle was complete. But as profits soared, Valerius noticed shadows that did not belong to merchants. Spies from other nations, disguised as porters, began to study the rail structure and the strength of the Orcs.
"Success attracts rats, my Lord," Valerius murmured, brushing a speck of marble dust from his sleeve. "Perhaps it is time to give this station not just administrators, but an eye that sees through lies."
The resounding success of the Alabaster Outpost was the final argument King Gazel Dwargo needed. Seeing the sheer tonnage of goods moved effortlessly by Geld's Orcs over Szayelaporro's rails, the King of Dwarves understood that Dwargon's future depended on being physically linked to this system.
Gazel Dwargo sent a diplomatic ultimatum, delivered with a rare tone of enthusiasm: "Sirzechs, Rimuru... my dwarves are masters of metal, but your rails are the arteries of tomorrow. I want the Great Way to climb the Mountains of Dwargon. If you do this, the steel from my forges will flow to Avalon at cost price."
The proposal was irresistible, but the technical challenge was monumental. The route to Dwargon required climbing steep inclines and piercing through solid granite ridges. Sirzechs summoned Szayelaporro and the Orc leader, Geld, to the royal study.
"Expansion into Dwargon is not just a matter of laying tracks," Szayelaporro explained, projecting a magical light hologram over the map. "It requires drilling straight tunnels so our cargo convoys do not lose their moment of inertia. We must pierce the mountain."
Under Szayelaporro's guidance, Avalon's technology merged with Orc brute force in a project called "Operation Marble Drill." Szayelaporro developed drill bits made of hardened steel infused with marble dust and magicules, capable of vibrating at frequencies that shattered the hardest rock. Geld, leading a thousand Orcs, commanded the drilling teams. There were no engines; the Orcs themselves turned the massive cranks of reduction gears, transforming muscular power into devastating rotation.
The railway expansion became an engineering marvel:
The Marble Viaducts: To cross canyons, Szayelaporro designed double-arch bridges in reinforced marble, so solid that the impact of passing convoys was absorbed without vibration.
The King's Tunnel: A five-kilometer bore through the heart of the mountain. Where dwarves would have taken years to pick away, Geld's Orcs, guided by Szayelaporro's calculations, finished in weeks.
The Counter-Load Braking System: For steep descents, Szayelaporro installed a system of pulleys and counterweights onto the tracks, ensuring that the weight of loaded convoys never spiraled out of control.
As the work progressed, Sirzechs watched from the heights of one of the new viaducts. The rhythmic sound of pickaxes and the roar of the drilling machines were the new music of Jura. However, the expansion toward Dwargon brought the rails closer to the borders of the Eastern Empire and the influence zones of other Demon Lords.
"Lord Sirzechs," Valerius said, appearing like a shadow on the viaduct, "King Gazel is satisfied, but the noise of our drills is waking those who would prefer Jura to remain an isolated forest."
"Let them wake," Sirzechs replied, his crimson gaze fixed on the tunnel that now linked three nations. "With every kilometer of rail, our sovereignty hardens. Avalon is no longer just a city; it is the origin point of a new world order."
The completion of the Dwargon-Avalon-Tempest line marked the birth of the Iron Triangle. Now, Dwargon ore reached Avalon in hours, was processed by Szayelaporro's science, and sent to Tempest as tools and weapons. But with infrastructure now spanning hundreds of kilometers, vulnerability grew.
