The expansion of the Terra Republic was no longer a crawl; it was a deluge of concrete and steel. As the frontier lines pushed past the jagged peaks of the interior, the first survey teams finally crested the western coastal ranges. Below them lay the vast, gray expanse of the Great Sea. For a people who had spent a decade hemmed in by ice and rock, the sight of the horizon was the signal for a new industrial frontier.
Under the direct orders of President Edward McDowell, the first coastal hubs were established in the deep fjords of the west. Within months, the silence of the cliffs was replaced by the rhythmic thud of industrial pile drivers. Huge concrete docks were extended into the cold waters, facilitating the creation of massive naval yards. Here, engineers began the construction of high-endurance fishing trawlers to feed the Republic's millions, alongside the first vessels of the Terran Navy.
Equipped with sonar arrays to track biological signatures in the deep and magnetic-firearm turrets, the first fleet of destroyers and specialized submarines began their patrols. They were not hunting for enemy nations—of which they believed there were none—but were neutralizing "abnormal" aquatic predators. These behemoths of the deep posed a significant threat to the Republic's budding maritime trade and fishing companies. To the Terran sailors, the sea was simply a resource to be harvested under the protection of silver-tipped torpedoes and magnetic depth charges.
However, the threat was not confined to the land and sea. High-altitude sensors and orbital satellites began flagging "bio-aero" signatures—massive flying entities that inhabited the thermal currents of the northern peaks.
"We cannot risk our commercial aeroplanes or our remaining colony-ship shuttles being intercepted by territorial avian predators," General Marcus White argued during a closed-door session of the New Terran Congress. "A single collision with a high-mass flying organism could cost us years of engineering progress."
The response was the immediate implementation of the Terran Air Force. Sleek, aerodynamically superior interceptors were rolled out of the mountain hangars. Unlike the heavy transport ships, these were built for the "Clearing." Equipped with advanced radar and nose-mounted magnetic firearms, the pilots began systematic sweeps of the northern airspace. Any flying creature that entered the Republic's designated flight corridors was met with a burst of high-velocity lead or silver.
With the establishment of the Air Force, the Republic's military reached its final, matured form. They now possessed a Tri-Element Command: Land, Naval, and Air.
The nation was now a fortress of three dimensions. From the submarines silent in the western depths to the jet-trails bisecting the clouds, the Terra Republic had secured its footing. The progress was rapid and uninterrupted; the abundance of ores, gases, and oils from the newly absorbed territories fueled a golden age of technology. In the cities, the lights never went out, and on the borders, the "abnormalities" were being pushed further into the dark.
For the people of Terra 2, the world remained a vast, empty wilderness they were destined to fill. Their satellites mapped the geography of the giant planet, but their eyes remained fixed on their own borders, oblivious to the fact that beyond the mountain ranges and across the distant plains, other civilizations of men and monsters lived in the shadow of a history the Terrans had yet to discover.

The geography of the North was no longer a map of terrain, but a map of overlapping kill-zones.
Despite the effectiveness of the Tri-Element Command, the sheer scale of the giant planet posed a challenge. The wilderness was deep, and the "abnormal" lifeforms were relentless in their attempts to reclaim territory. President Edward McDowell, ever the pragmatist, realized that human eyes and hands could not be everywhere at once. Under his directive, the Republic moved to the next phase of its defense: the Automated Perimeter Initiative.
The borders of the Terra Republic were transformed into a wall of high-tech sensors and kinetic fury. Thousands of Shredder Turrets were deployed along the forest fringes and mountain passes. These were rapid-fire magnetic automated shooters, programmed to identify and eliminate swarms of low-mass biological threats. When the motion sensors detected a horde of ground-based creatures, the Shredders would pivot with millisecond precision, painting the snow red with a storm of lead or silver-alloy rounds before a human soldier even reached for a radio.
For the larger, more resilient specimens that shrugged off standard ballistics, the Laser Turrets were installed. These heavy-duty energy projectors were reserved for the "tough" opponents—monstrosities with thick, regenerative hides or armored carapaces. The silent, searing beams could cut through bone and muscle in a single pulse, providing a high-intensity solution where kinetic rounds failed.
The sky, too, was placed under the watch of the machine. SAM Turrets—Surface-to-Air Missile batteries—were positioned on the highest peaks of the Republic's territory. These units were slaved to the orbital satellite network, capable of locking onto high-velocity aerial threats from kilometers away. Whether it was a territorial avian predator or a massive flying beast, the SAM systems ensured that the Republic's airspace remained a no-fly zone for any non-Terran signature.
"We have achieved total security," General Marcus White reported during a briefing at the High Command Bunker. "The manpower is no longer our bottleneck. The machines do the clearing; our people do the building."
To further reinforce this mechanical wall, the Republic began the construction of a secondary layer of defense. Massive, lead-shielded Bunkers were sunk into the bedrock at strategic intervals, serving as hardened shelters and supply hubs for the frontier guards. Towering above them were the Sniper Towers—armored needles of steel equipped with thermal optics and long-range magnetic rifles. These towers provided the human element of oversight, allowing elite marksmen to pick off any anomaly that managed to find a blind spot in the automated grid.
With the implementation of the "Shredders," the "Lasers," and the "SAMs," the safety of the nation was absolute. Behind this curtain of fire, the citizens of Terra 2 lived in a state of unprecedented peace. Children played in the parks of cities that never saw a monster, and scholars worked in universities where "The Abnormalities" were discussed only as solved biological equations.
The Terra Republic was no longer just a colony; it was a fortress-state of science. They had built a world where the dark held no terrors, and for the stubborn people of Terra, the wild world beyond their sensors was simply a matter of time and further expansion.
