Grayson stood on the basalt ridge above the cave, morning heat already pressing down. His lace flickered with metrics—temperature spikes, soil chemistry trending toward sterile, atmospheric CO₂ still climbing despite his early trials. Every number screamed imbalance.
Egg's voice was steady. "Earth has confronted imbalance before. The biosphere has produced radical corrections, given time."
"Except we don't have millions of years," Grayson said.
"Correct. But we have their blueprints."
The lace pulsed. Grayson staggered, not from pain but from sudden immersion. His perception exploded outward—forests of the Carboniferous era, towering ferns and lycopsids stretching forty meters high, spore clouds rolling like storms. Oxygen levels surged, insects the size of hawks buzzed through the canopy. Beneath them, swamp soils locked away mountains of carbon, lignin-petrified trunks piling into the strata. He felt the drawdown curve in his gut.
"Life already ran this experiment," Egg narrated. "High CO₂. Rapid plant expansion. Atmospheric correction. Your task is to accelerate."
Grayson's awe broke through his skepticism. "It's beautiful. It's like the planet decided to plant a lung."
"More precisely," Egg said, "a filter. But that strategy will fail if copied directly. Modern microbes digest lignin readily. You would gain nothing."
"So I need an upgrade."
"Correct. Nanostructured carbon analogues. In your terms—carbon nanotubes, woven by biology. Harder to break down. Longer residence time. Every trunk a composite material."
Grayson rubbed his chin, eyes still full of fern canopies dissolving into sky. "So… forests made of scaffolding stronger than steel. That's not just a carbon sink. That's infrastructure."
Egg pulsed a confirmation. "If you stabilize the code, yes. But such material will accumulate. You must design recyclers, grazers, and error handlers—or you will bury the biosphere in its own skeleton."
The vision shifted again: Cambrian seas bursting with trilobites and filter-feeders, evolutionary experiments flashing and failing in rapid cycles. Grayson felt dizzy, overwhelmed by the raw possibility of it all.
His voice cracked. "I'm not building organisms. I'm building eras."
"Precisely," Egg said. "And eras require balance."

New Option Unlocked: Nanostructured Biomaterials (carbon nanotube analogues).
Grayson crouched by the printer array, watching a line of gene-simulation windows cascade through his lace. Each new trial was a Frankenstein of old blueprints and modern upgrades. He had reprioritized his sequence queue: ferns, mosses, proto-trees—ancient scaffolds for a dying biosphere.
The first fern prototype unfurled in simulation, its fronds huge and waxy. Within days of simulated growth, microbes swarmed it, chewing through the carbon lattice. Collapse.
Egg's verdict was immediate. "As predicted. Lignin is no longer protection. Too many organisms evolved enzymes to digest it."
Grayson rubbed his jaw. "So we need something lignin-like, but tougher. You said carbon nanotube analogues—what does that look like biologically?"
Egg overlaid a model: cellulose fibers reinforced with carbon in two-dimensional sheets. "Graphene," Egg explained. "Metabolically expensive, but not indestructible. Strong enough to resist breakdown, yet over decades it fractures and oxidizes. The worst-case outcome is accumulation as graphite—atom-thick layers, harmless, even beneficial, in soil and sediment."
Grayson grinned at the image of glittering black flakes sifting through topsoil. "So the forests won't fossilize into diamond skeletons. They'll… shed stardust."
"An acceptable metaphor," Egg replied. "Durable, but not eternal. Manageable permanence."
Grayson dragged the graphene sequence into his fern model. The sim pulsed, fronds glowing faintly as tissues hardened into reinforced scaffolds. The plant survived weeks, then months. Graphs ticked upward. Oxygen stable, carbon drawdown positive. Finally, failure—nutrient starvation.
"Error handler required," Egg said calmly. "Add nutrient recyclers. Fungi. Soil grazers."
Grayson layered in fungal partners. Hyphae latticed through the soil, trading minerals for carbohydrates. This time the fern grew taller, sturdier. Spore clouds burst from its fronds, drifting on simulated wind. They shimmered faintly—he'd spliced in a bioluminescent pathway, half for monitoring, half for sheer wonder. At night, the canopy looked like galaxies blowing across the forest floor.
When he snapped a simulated branch in irritation during a later failure run, he noticed a smear of dark streak across the ground plane. He blinked, leaned closer, and rubbed his fingers against it. The smear deepened like pencil lead. Grayson chuckled. "Well, that's a side effect. These things double as pencils."
"Graphene exfoliates easily into graphite," Egg confirmed. "Your forests may incidentally provide infinite writing implements."
Grayson smirked. "Great. I'm fixing the carbon cycle and stationery shortages."
The sim ran long enough to stabilize a mini-forest—then the models flickered red. Fronds overgrew their base, collapsing in their own mass. Error again.
Grayson sighed. "So what's the fix this time?"
Egg: "Grazers. As with coral. Organisms to consume excess tissue and return nutrients. Balance requires feeders at every layer."
Grayson nodded slowly. He wasn't planting organisms anymore. He was coding food webs.

Grayson leaned back against the basalt wall, reviewing the latest failed run. The graphene ferns grew tall and luminous, spores glittering across the canopy, but in the end they collapsed under their own mass. Too much growth, not enough regulation.
Egg's voice cut through. "Balance requires more than architecture. It requires consumers. Grazers, parasites, and detritivores. Error handlers, not ornaments."
"Yeah, yeah," Grayson muttered, dragging new icons into the sim. "Let's see what happens when we add something with teeth."
The sandbox filled with movement. Small reptilian grazers nibbled fronds, clipping back overgrowth. Their waste scattered calcium-rich pellets across the soil, tiny nutrient packets feeding the fungi. Worm analogues burrowed, digesting detritus, leaving aerated tunnels. The ecosystem graphs shifted—carbon still positive, oxygen stable, nutrient flux oscillating instead of flatlining.
Grayson zoomed in on one grazer, watching it bite into a glowing frond. The branch cracked, smearing black graphite across its snout. He laughed. "Even the critters are going to end up doodling."
"Unintended, but harmless," Egg observed. "Excreted graphite will accumulate in sediments. Manageable permanence."
The run survived a simulated decade. Graphs climbed, dipped, but never bottomed out. It was the longest success yet.
Grayson rubbed at his eyes, feeling the lace stream compressed insights into his thoughts—equations of trophic flow, metabolic balances, nutrient loops. It was exhilarating and suffocating at once. "I feel like I'm skipping ahead of myself. Like I'm not learning this, just… remembering it."
"The lace accelerates pattern recognition," Egg replied. "But remember: recognition is not mastery. You must still iterate, practice and apply."
Grayson nodded, then dragged in new organisms: micro-predators to keep grazer populations in check, parasites coded to skim metabolic surpluses, and symbiotic microbes engineered to recycle trace elements before they slipped out of the loop. The sandbox grew more crowded, more dynamic—yet the graphs smoothed again, stabilizing instead of spiraling.
He watched as a grazer twitched under a parasite's bite, only to keep feeding, undeterred. Its waste carried richer nutrients, already inoculated by the microbe. "So even scraps and inefficiencies stay in circulation," Grayson murmured. "Nothing gets lost."
"Correct," Egg said. "An ecosystem without leakages sustains itself longer. Predators, parasites, and symbionts ensure every margin is captured."
Grayson gestured at the glowing mini-forest, grazers scurrying between trunks, worms tunneling below, and glittering spores drifting like starlight. "Still, it feels like the first time something I planted didn't just keel over."
Egg paused before answering. "Projected survivability: eighty years. Fragile, but viable. It allows time for refinement and correction, perhaps opening niches for natural adaptation as well."
Grayson let out a slow breath. "So, not just plants anymore. Whole loops. Whole webs."
"Correct. You are coding ecosystems, not organisms. This is the threshold of ecological engineering."

———
Grayson stood at the mouth of the cave, the first batch of graphene ferns planted along the slope below. They were only weeks old, yet already waist-high, fronds shimmering faintly in the night. Spores drifted upward like galaxies spilling into the sky, riding the winds far beyond his test patch.
Egg's voice was low. "Containment protocols breached. Your organisms are dispersing outside intended boundaries. You may terminate immediately."
Grayson clenched his fists. He knew a single command could trigger the failsafe frequency, reduce the plants to slurry in minutes. But his chest tightened at the thought. "It's the first time I've seen this island alive. If I pull the plug now, I'm back to gray stone."
He crouched, brushing a finger across a fern's stalk. It left a graphite smear on his skin. He frowned, examining it in the glow of his HUD. "That's… interesting. Graphite flakes are binding salts in the soil. Look—sodium levels dropped by twenty percent since last scan."
Egg confirmed. "Correct. Graphite layers are adsorbing excess ions. Secondary benefit: soil desalination."
Grayson's eyes widened. "So they're not just carbon sinks. They're cleaning the ground."
He swept his gaze across the slope. At the base of the patch, he spotted worms burrowing where runoff pooled. They hadn't been part of his deployment. Curious, he checked the scan overlay. "The native detritivores are colonizing it already. They're eating the fallen fronds."
Graphs spiked green in his vision—nutrient flow rising, microbial diversity expanding. The whole slope was waking up. He could almost hear it breathing.
Egg pressed again. "Uncontrolled dispersal increases risk. Probability of archipelago-wide colonization: 72 percent within one year."
Grayson swallowed hard, torn between alarm and awe. "But look at it. The worms are thicker already. The birds are picking at the berries. It's feeding the system faster than anything else we've tried."
He stared into the night sky, where spore clouds drifted like glowing nebulae toward the neighboring ridge. His finger hovered over the termination command. His heart pounded.
Finally, he dropped his hand. "We let it run. I need to see what happens when the system pushes back."
Egg logged the decision without commentary. The glow spread across the black rock like veins of living fire, and for the first time, Grayson felt the island was no longer empty.
