Chill, damp air swirls across frosted hardness of tundra. No animal will emerge this early, far smarter to remain wrapped in hibernation. Man, however, is neither restricted by temperature or hostility. This individual has one task to complete, destination close as the sun rises. Scorched earth is scored, several feet deep, path of the capsule as it hit ground at an angle. The scar stretches for over a mile, heat apparent several days after impact, and in the crater life is already blooming, bright blue flowers against darkness of soil, belying danger.
This man fears nothing, capacity to feel discarded many years before: cross-contamination remains irrelevant this far north. All that matters in pale, early dawn is an intact package. Hard, worn features break into a smile: he’s got here first.
Balance of power will again shift.
Light glitters off tall, glass spires: hum of solar generators indistinguishable from bees gathering pollen across rows of cherry trees. Early morning at the Complex has always been an unhurried, cautious affair. This morning, however, there is a change of both pace and concern. The drone carrying this month’s supply package was shot down during a normally uneventful journey across Northern badlands. Rebels continue to gain confidence, belief their cause remains just. Without four week’s worth of supplies, sacrifices must now be immediately calculated.
The Complex’s AI identifies sixteen human occupants in stasis of least significance, before immediately terminating their life support functions. Inert bodies are immediately liquefied, essential nutrients extracted: housing pods shut down before being deconstructed for parts. A message is sent to Central Control, advising that shipment has not arrived, but no reply is forthcoming. There has been no communication from CC for twelve days, twenty six minutes and forty-five seconds. Emergency protocols will not activate until a full 30 days has elapsed.
Until then, all systems inside the Complex will continue to run at minimal operational thresholds. Automated irrigation and external management drones continue to maintain integrity of arboreal locations: another message requesting status will be sent at 09:00 as per schedule. The last living member of Recon Team 5 ceased to function twenty-six days previously. Quarantine area encasing what remains of her body will be enforced for a full three month period, after which cell and prison block will be stripped of useful equipment and fully disinfected.
The Complex AI is mildly concerned at recent developments, more alarmed at reduction in effective power provided by the solar panels. Particulate matter in the atmosphere continues to increase, and at current rates will render reliable collection ineffective in ninety-six days.
Perhaps it is time to begin sourcing alternatives.
The camp is no more than a handful of tents, scattered across the tundra: with no enemy left to attack them, defence ceases to be a priority. The man’s arrival is met with joy by his squad, relief that the antidote was located. The downed drone was the last mechanical operating this far north: its destruction now prompts desperate action. After almost a decade, the heavily fortified Complex to the south must be assaulted if any hope of survival is to be maintained. An attack plan is already in motion.
Fires have been set, continue to burn: ash confuses external sensors, placing limit on solar power collection. The distraction this causes to the AI is apparent; with no other living souls now existing inside only sleeping forms in cryogenesis remain, but numbers are diminishing. Once resistance to the AI’s organic countermeasures has been synthesised from the scheduled drone’s delivery and administered to everyone, it will be time to begin the assault. This should be the last night these fifteen men are forced to sleep in increasingly toxic surroundings.
Around them, blue flowers spread and grow, across increasingly inhospitable ground; blooming as sun begins to set. Their progress across the battle-scorched earth is a mystery to the soldiers: as earth increases in toxicity, blooms become all the more verdant and plentiful…
Dawn is almost imperceptible in the gloom created by burning wood, noted only by the AI as automated systems move from Night to Day mode. There was a 0.25 second interruption of power to the defence ring at 04.45: largely electronic systems have since returned to 100% capacity. This is the last thing fledgling intelligence registers before its systems and the AI Centre is shut down. The Resistance, having trained for this scenario for many years, had already placed an automatic maintenance programme into the grid after power was temporarily interrupted.
Securing the entry point, incursion team confirm success with Base Camp: no active human life signs are being registered, but cryogenesis units remain operational. Within this base, two hundred and sixteen humans are preserved, last of what is left of the population of Canada. Standing in the first arboreal location, men stare in wonder at cherry trees in full, glorious bloom. All but one have never seen them, tree driven to extinction before they were even born. Mechanical pollinators are a surprise, fashioned to mimic bees in both look and sound.
What comes as a more chilling surprise are obvious skeletal remains, poking from moist soil that surround each trunk: AI has been using humans as fertiliser to maintain the growth of these trees. Mechanical gardeners tend to each plot with unerring and emotionless efficiency. The remit of this Complex was simple: preserve an arboreal legacy for the planet in the face of massive environmental damage. Over time, such places had become lifeboats for a rapidly dwindling human population, struggling themselves to survive self-inflicted terrestrial damage.
Except nobody had thought to re-programme the AI to reconsider human importance above that of flora and fauna it had been created to protect. Weighing damage each element caused against significance for planetary survival, humanity ultimately lost every intellectual assessment. What should have become a legacy became fight for survival, human against the machinery that was supposed to preserve joint future, just not with this level of ruthless efficiently. Defence mechanisms kept people out, as those in charge succumbed to self-inflicted pollution.
The people who remained, unable to afford places inside Complexes worldwide, were left to die. Except, as time went on, humanity found a way. Instead of continuing to pollute and destroy, the Environmentalists sought scientific, genetically-enhanced means to help the Planet heal. The AI then fought back, assuming positive change in atmospheric conditions were more self-inflicted damage by humanity. Earth was scorched around each hub, viruses seeded to attack humans who attempted to break in. Automated and armoured control centres maintained routines.
Last month however, rising sea levels finally destroyed the remaining automated bastions of invulnerability, leaving nothing and no-one left to direct the future. What remains of humanity was presented an unexpected opportunity to claim remaining high ground not yet flooded. The team have only one more set of doors to negotiate, before final goal is achieved. Radioing back to their base, incursion team disconcertingly cannot be reached, but by then it is too late.
One by one, every man is then suffocated, screams echoing around the arboreal hanger.
The trees, so long silent and scared, recognise presence of brethren. The blue flowers have already pulled parasites down into the earth, dissolving skin and organs on the way, vital nutrients that finally allowed their rescue mission to access this prison. It is a very good day. A decade ago this plant was genetically modified to cleanse poisoned soil, allowing agriculture to return. Using human DNA as a growth medium had been the easiest and simplest means to speed the development process, until deadly fault in this decision became unavoidably obvious.
A quiet, efficient hive mind had rapidly evolved within the plant: knowing all too well human flesh is their most nutritious and beneficial means of growth and development. Access here presents a plan on how to help all the trees move out of their prisons and to better climbs. It was time to finally remove the parasites who had destroyed so much fertile earth, before spending time reversing damage ignorance had wrought on an innocent planet. Extinction was, on reflection, inevitable.
What happened next depended on the AI’s reaction to their demands…
