Deep beneath the Earth, far below the molten oceans of magma and the crushing pressure of the planet's core, existed a hidden space that no mortal could ever reach. It was not a physical location in the traditional sense, but a dimensional pocket connected directly to the System itself. Inside that impossible place sat a woman of indescribable beauty before a large television screen, lazily watching human reality shows while wrapped in a blanket on a comfortable couch. The room around her looked surprisingly ordinary, no larger than an average living room, complete with shelves, warm lighting, and half-finished snacks scattered across a small table. If any human had seen the scene, they would never have guessed that the being currently binge-watching television was the consciousness of the planet itself.
"Well then," the woman sighed while stretching her arms above her head, "I suppose it's finally time to expand the Earth." The moment she turned off the television, the cozy room dissolved instantly into streams of glowing particles. In its place appeared a vast futuristic chamber lined with transparent screens and rotating holograms. At the center floated a massive projection of Earth slowly spinning in midair, surrounded by countless streams of data. The woman rose calmly from her chair and walked toward the hologram with the relaxed attitude of someone preparing for routine office work rather than a planetary transformation.
Her name was Gaia.
Or rather, it had become Gaia.
"I still think those brats cursed me with this appearance," she muttered with mild dissatisfaction while observing her reflection in one of the floating displays. "The first people to properly name me just had to choose Gaia." The name carried tremendous symbolic meaning among humans, especially within Greek mythology where Gaia represented Mother Earth itself. Unfortunately for her, names carried power. The moment a group of humans associated the planetary ego with that concept, her form permanently stabilized into that of a beautiful woman. Not that she truly hated it anymore. After all, she had long since stopped caring about things like gender. Immortality tended to erode those kinds of attachments eventually.
Gaia herself was not truly alive in the same way humans were. She was Earth's ego, the planetary consciousness born from the interaction between intelligent civilization and dark matter. Under normal circumstances, such an awakening would have taken billions of years within a region of space where advanced civilizations regularly manipulated dark matter technologies. Earth had not been around long enough for her to awaken naturally. Humanity barely possessed successful moon bases, and most of their larger space programs remained incomplete fantasies. From a cosmic perspective, they were little more than children playing with fire.
Still, compared to some civilizations Gaia knew about, humanity was downright harmless.
"I'm still jealous of that one," Gaia muttered while scrolling through old cosmic records. Somewhere in the universe existed a naturally long-lived species that had successfully conquered an entire galaxy before their planetary consciousness awakened. Worse still, they had exterminated nearly every intelligent species within that galaxy beforehand. Because of that, their civilization survived the awakening process almost untouched and adapted seamlessly to individuals manipulating dark matter. Their military standards already included defenses against mana corruption and dimensional warfare long before their planet awakened. Compared to them, humanity was painfully primitive.
Meanwhile, she was stuck babysitting a species that still argued online about conspiracy theories and celebrity scandals.
Still, they were her humans.
And whether she liked it or not, the expansion had to begin soon.
Gaia waved her hand lightly, causing the holographic Earth to split apart into countless layers displaying underground structures, mana density, cultural energy concentration, and continental fault lines. "First things first," she said calmly. "Let's verify the mana veins." Her eyes glowed softly as the planet responded to her will. Deep beneath mountains, oceans, forests, and ancient ruins, glowing rivers of mana became visible across the projection. They resembled luminous arteries stretching through the body of the world itself.
Mana veins were essential for planetary health.
Mana naturally gathered around concentrated cultural energy, especially around civilizations. Once enough cultural energy accumulated in an area, mana would slowly encase it like a protective shell. Over time, that shell thickened until it became almost impossible for anyone except the planetary core itself to absorb the energy within. The Earth's core then consumed that refined cultural energy for maintenance, growth, and evolution. The veins existed to transport that energy efficiently throughout the planet.
"That explains why places like the Sonneberg forest became mana rich," Gaia murmured thoughtfully. Areas where cultural energy frequently peeled away from the surrounding mana shells naturally accumulated dense ambient mana over centuries. Ancient battlefields, sacred sites, and long-standing family territories often became hotspots because of this process. Humanity viewed such places as mystical or spiritual without realizing there was an actual biological mechanism behind them.
"Everything seems stable," Gaia concluded after finishing her inspection. "Good." That was one less disaster to worry about.
Unfortunately, the actual expansion process remained a nightmare.
Gaia crossed her arms while staring at the rotating Earth hologram with visible frustration. Expanding the planet itself was easy. The difficult part was preserving humanity's infrastructure and geography in ways humans could psychologically tolerate. Cities possessed enormous concentrations of cultural energy, meaning they would resist physical distortion during expansion. Mana veins behaved similarly. As a result, the land between those points would stretch unevenly rather than proportionally.
Most cities could simply be enlarged alongside their surroundings without issue.
Special locations, however, created logistical nightmares.
"Take Rotterdam for example," Gaia muttered while highlighting Europe on the hologram. "Largest port in Europe." If she expanded the continent carelessly, Rotterdam could suddenly become trapped deep inside an inland bay rather than remaining directly connected to the sea. The city's entire economic structure would collapse almost overnight as sediment buildup and altered currents ruined shipping routes. Similar issues existed everywhere. Rivers, mountain passes, coastlines, and transportation hubs all required careful adjustment.
Human civilization was fragile.
Far more fragile than humans themselves realized.
At least the cities still served a useful purpose. Humanity's obsession with wealth and commerce unintentionally generated tremendous amounts of cultural energy. Coins themselves had become particularly valuable after the System arrived because every transaction carried traces of human intent, desire, and free will. The System stores absorbed that energy slowly through exchanges, producing far more profit for Gaia than humanity could ever imagine.
Still, economic benefits were secondary compared to what came next.
Gaia zoomed the hologram outward and sighed heavily. "The real problem is technology." Modern human infrastructure was catastrophically vulnerable to mana contamination. Satellites, internet cables, power grids, processors, and delicate machinery all suffered from the same flaw: they lacked cultural reinforcement. Most advanced components were manufactured by automated systems, with minimal direct human craftsmanship. Because of that, they contained almost no stable cultural energy and would collapse almost immediately once exposed to high ambient mana density.
"If humans could build processors by hand, they'd survive much longer," Gaia admitted. "But that's impossible for them right now." Not that she particularly minded. The destruction of modern infrastructure would release absurd amounts of unclaimed cultural energy back into the planet. Humanity spent centuries coating the world with artificial systems, only for mana to erase 90% of them overnight.
From Gaia's perspective, it was less a disaster and more a planetary reset.
As humanity retreated into fortified cities, vast portions of Earth would finally recover from centuries of industrial abuse. Oceans polluted by chemicals would cleanse themselves through mana saturation. Forests would regrow at accelerated rates. Animal populations would explode as biodiversity restoration protocols were automatically activated during expansion. Even invasive species would be relocated toward their original habitats unless humans actively relied upon them for survival.
"A proper planet needs balance," Gaia muttered quietly while adjusting continental growth parameters. "And humans have made an unbelievable mess." Despite her complaints, there was no true hatred in her voice. If anything, Gaia sounded like an exhausted mother cleaning up after reckless children.
Her fingers danced across floating screens as she finalized environmental restoration protocols. Toxic regions would heal first. Oceans would deepen. Freshwater systems would stabilize. Forests would expand naturally along mana-rich zones. Animal breeding rates would accelerate slightly to restore ecological competition. Even the atmosphere itself would thicken marginally to better circulate mana across the planet.
