The Marvel universe had standards for impossible that would have embarrassed a fever dream. Michael Clyborne had been living inside those standards long enough to stop arguing with them.
He had arrived with another man's face, an unearned fortune and a manor that made every apartment from his first life feel theoretical. The system had supplied the identity and the money.
For several days, Michael had treated both as proof that reincarnation came with an apology package.
Then he remembered where he was.
Money would not stop an alien invasion. A wine cellar would not discourage a god. The sports cars might let him die at a more interesting speed, but that was about the extent of their tactical value.
Michael stood at the front windows and called up the interface. Pale text unfolded across his vision.
Host: Michael Clyborne.
Gene collection: none.
Available functions: regional time manipulation, regional environmental transformation, gene-chain rationalization.
It was not an invincibility package. The system could seed biological spores inside a bounded environment, accelerate their development, and stabilize whatever genetics survived the result. If a new organism met its standards, Michael could incorporate its form.
That last part had made him picture wings, armor, perhaps something immortal.
The system had answered the fantasy before he voiced it.
"A sufficiently powerful creation may kill its creator."
Michael stared at the words. "Do you have any safety features at all?"
"To create life is to accept the corresponding risk."
It had the bedside manner of a land mine.
Michael tested the wording from three angles and found no comfort. The system could rationalize a stable gene chain after a species survived. It could not promise loyalty, reverse a hostile decision or protect him from the intelligence he encouraged.
Whatever emerged would be alive before it became useful. The enclosure felt less like a laboratory appliance than a country whose first citizen had not yet been born.
He dismissed the interface and looked across the manor grounds. The lesson was obvious, if irritating. He could not begin with a god. He needed something durable, useful, and small enough to contain if it developed opinions about him.
The system's current reach extended five hundred meters in every direction. Michael established the genetic sandbox beginning ten meters beyond the front entrance, where he could observe it from the house without placing its boundary directly against the walls.
To anyone else, the lawn remained lawn. Michael saw a thin shimmer settle across the air.
The environmental controls could modify what already existed, not conjure an entirely different planet. Grass remained grass. Soil remained soil. The spores were resilient, but resilience raised an immediate problem: comfort would teach them nothing.
His first idea was a volcano.
It survived for roughly one second.
"No," Michael said. "I'd prefer not to explain molten landscaping to my insurance company."
Cold, then.
"Lower the regional temperature to minus thirty."
Frost raced over the enclosed lawn. Michael dragged a hose to the boundary and watched water spread across the ground. Ice formed faster than the flow could escape it.
He left the hose running for three hours, shifting it whenever the growing sheet threatened to trap the nozzle. By then the sandbox held a broad frozen field.
On one side of the boundary, summer air pressed warm against his skin. On the other, snow drove over blue-white ice. The membrane between them looked offensively delicate.
Michael rubbed his hands together. "Release the spores. Accelerate regional time."
He chose a prolonged span and watched the enclosure. For nearly an hour by his own clock, nothing happened.
Then dark points spread through the frozen soil.
Most became low, pine-like growths. Their needles folded tight against the cold while their roots worried into cracks in the ice. Other spores took a different path. Tiny bodies lengthened. Limbs emerged, followed by crude mouths and sensory pits.
Michael leaned closer to the boundary.
The creatures were no larger than ants. They crawled toward the grass beyond the thickest ice, but had never passed through an aquatic stage or developed the structure to support themselves properly. Even movement cost them.
At the frozen pasture, their mouthparts scraped uselessly against blades harder than steel at their scale.
The first generation starved.
There was no drama to it. No heroic adaptation arrived at the final second. They slowed, stopped, and vanished beneath new frost as accelerated years continued around them.
Michael watched until the last moving shape went still.
He had known the system was an evolutionary engine. It had been easier to admire that phrase before evolution filled the garden with bodies.
The pine-like organisms endured.
"So that's the threshold," he murmured. Life first. Mercy, apparently, if available.
The doorbell rang.
Michael's head snapped toward the house. The grounds were empty by design. He had dismissed the staff for the day, and almost no one visited without calling.
S.H.I.E.L.D. came to mind at once.
He pulled out his phone and opened the gate camera. A teenage boy stood outside with a backpack hanging from one shoulder. His eyes were red, and although Michael knew the face, recognition arrived a second before the name.
Peter Parker.
Michael opened the intercom. "Can I help you?"
Peter looked directly at the camera and held up an old photograph. A man and woman stood together on their wedding day, the colors faded around their smiles.
"Are you Mr. Clyborne?" Peter asked. "Do you have a cousin named May Parker?"
Something shifted behind Michael's eyes.
The body remembered what he did not: childhood visits, two close branches of a family, then an accident and years of silence between their parents.
May was not his cousin by blood as Michael understood himself. She was the cousin of the identity the system had placed around him.
"Uncle Ben died," Peter said. He tried to keep his voice steady and failed. "May keeps saying she's fine, but I've heard her crying when she thinks I'm asleep. She wouldn't let me contact you. I thought maybe… you're the only family she has left."
Michael glanced back at the frozen enclosure. The surviving growths had not changed. Whatever came next would take time, at least from his side of the boundary.
"Wait there," he said. "I'll change and drive you."
Relief loosened Peter's shoulders. "Thank you, Mr. Clyborne."
"Michael is fine."
He ended the call before Peter could ask to come inside.
Through the camera, Michael watched the boy look at the locked gate, then at the enormous house beyond it. Peter muttered something that the microphone barely caught about family manners and being offered a chair.
Michael almost opened the gate. Then he looked at the impossible winter occupying his lawn.
Letting Peter into the manor on their first meeting would risk exposing the system. Silencing him afterward would be excessive even by Michael's increasingly flexible standards.
He changed clothes, checked the sandbox once more, and locked the house behind him.
The pines stood beneath the snow, patient and alive.
