While Himari and Sakura navigated the treacherous politics of Silverwood, the fortress was undergoing a transformation from a passive shelter into an active military installation. The hum of the fabricator was a constant presence, a steady heartbeat pumping out the tools of a new kind of war. Under Haruto's direction, it produced high-yield power cells, advanced sensor components, and dozens of small, spider-like drones designed for reconnaissance and perimeter defense.
Akane, for her part, had turned the fortress courtyard into a grueling training ground. She drilled Kaito and Riku relentlessly, forging them into a security force that blended their innate warrior instincts with Imperial discipline. They learned to operate as a cohesive unit, communicating with simple hand signals, and to use their new equipment as an extension of their senses. One afternoon, Akane ran a simulation, using the spider-drones to mimic a coordinated attack on the fortress. Kaito and Riku, using the sensor network and their plasma weapons, successfully repelled the "attack" without a single drone reaching the inner walls.
"Their reaction time has improved by 400%," Akane reported to Haruto later, a note of genuine respect in her voice. "They have the potential to be elite operators."
The true test of their new systems came late one evening. Haruto was in the command center, running diagnostics on the newly installed perimeter sensor grid, when a soft, insistent alarm chimed through the hall. On the main holographic map, a series of red icons appeared at the edge of their five-kilometer detection range.

Haruto and Akane were at the console in an instant. Akane zoomed in on the contacts, her eyes narrowing. "A scouting party. Their formation is military in nature. Too organized for bandits."
"Agreed," Haruto said, his fingers flying across the holographic interface. "They're avoiding the open ground, using the terrain for cover. They're professionals." He activated the nearest reconnaissance drone, a silent, flying observer that detached itself from a high branch and soared towards the intruders.
The drone's optical feed appeared on a secondary screen. It showed ten figures, clad in dark leather armor and moving with a predatory grace. They weren't Black Guards. Their equipment was different, and they carried elegantly curved swords and compact crossbows. What truly set them apart were the faint, shimmering auras of energy that clung to them, visible only on the drone's multi-spectrum sensors.

Magic-users. A new, unknown variable. The continent of Ares was proving to be far more complex than he had anticipated.
"They're not moving towards us," Akane observed, tracing their path on the map. "Their trajectory will take them past our position, towards the mountains. It seems they haven't detected us."
"Let's keep it that way," Haruto decided. "This is an intelligence-gathering opportunity. We stay dark. We observe."
For the next hour, they tracked the mysterious squad. The drone followed them from a safe distance, its stealth systems rendering it invisible and silent. They watched as the squad efficiently and ruthlessly dispatched a Grayha that strayed into their path, their movements a blur of steel and crackling energy. They were an elite unit, clearly on a mission.
As the squad passed out of their sensor range, heading deep into the untamed wilderness of the mountains, Haruto leaned back, a thoughtful frown on his face. The world was bigger than the Duke's petty squabbles. There were other powers at play, factions with abilities that defied his scientific understanding.
"Akari," he said quietly. "Begin a new threat analysis file. Designation: 'Arcane Operatives.' Log all sensor data from this encounter. We need to know who they are, and what they're doing in our backyard."
The fortress was no longer just a shield against the monsters of the forest. It was now an eye, watching the silent, unseen wars of this strange new world. And Haruto knew, with a certainty that chilled him, that it was only a matter of time before one of those wars came knocking on their newly automated door.
