Tony called at an hour that made murder feel like a scheduling option.
"Have you ever seen the sun at four in the morning?" he asked.
Michael kept his eyes closed. "Yes. Usually because I haven't gone to bed. Why?"
"I have armor built for a god."
Michael opened one eye. "Did you build it, or did you steal wreckage and become emotionally attached?"
"Scientists don't steal. We conduct aggressive salvage. Are you coming or not?"
Tony described a metal with a magnetic response he could measure but not explain. The fragment was small, dark, and recovered from the Destroyer left behind by Thor's battle.
Uru, if Michael's borrowed memories were right. He was out of bed before Tony finished pretending not to care.
The Nakfoji form carried him to Malibu. By the time he passed through the laboratory wall, sunlight had replaced the storm and Tony had accumulated enough coffee to resent morning professionally.
The metal waited on a test stand beside a spread of sensor data. It was no larger than Tony's palm.
Tony looked at Michael's blue armor and translucent edges. "Are you going to explain that?"
Michael released the transformation. "A private project. That's the explanation you're getting."
Tony's attention sharpened. Curiosity and competition often reached his face in the same expression. He did not press, but Michael could almost hear new countermeasures entering a design queue.
Michael studied the fragment instead. "Uru?"
"That's what the preliminary material calls it. Hardness is only the beginning." Tony opened a test result. "Its internal field makes energy and structure behave like parts of the same system. I can model pieces, but I can't explain why the equations work."
"So you're building protection against Thor."
"I'm developing options. A man with a weapon that controls weather arrived without warning, fought a federal unit, and left. Assuming he'll remain friendly because he smiled afterward would be negligent."
Michael could not argue with that. Tony had learned the cost of having no answer prepared.
The workbench held another discovery: Howard Stark's archived film and the scaled model that had accompanied it.
"Fury returned the materials," Michael said.
"Yesterday." Tony's voice lost some of its edge. "The film was Howard's preferred communication method: praise hidden under enough theater that he never had to say it while alive."
Michael looked from the recording to the model. He remembered the function, not the derivation.
"Flatten the layout," he said. "Remove the buildings. Keep their positions and relative geometry."
"JARVIS, do it." This story is hosted at g.com.
The projection collapsed from a city into a plane. Roads became bonds. Pavilions became nodes. The arrangement resolved into an elemental structure.
Tony went silent. Michael did not interrupt. Tony had already created a working replacement for palladium; Howard's model was no last-minute rescue.
It showed that Howard had approached the same class of problem and trusted his son to finish a language he could not complete.
"He was ahead of his time," Tony said at last.
"And you were ahead of his solution."
Tony studied the projection for another moment, then shut it down. "Take the Uru. You've been staring at it since you arrived. It's distracting."
"Generous. Suspicious, but generous."
"Consider it rent for the space you're occupying in my laboratory."
Michael picked up the fragment. Even inert, it carried a density the scale did not explain. The sandbox might turn its unusual bond with energy into something alive—or destroy another generation of spores trying.
He should have stopped asking for favors there. "I also need an artificial intelligence."
Tony stared at him. "Would you like the house? Pepper? My remaining dignity?"
"Independent. No link to JARVIS, no remote access, no reports returning to you."
"JARVIS can provide a subroutine."
"Then it remains part of your system."
Tony's amusement disappeared. "What are you hiding?"
"Something that isn't mine alone to reveal yet." Michael set his phone on the bench rather than hand it over. "I trust you. I don't trust every system connected to you, or anyone who decides your access is easier to break than mine."
Tony disliked the boundary. Michael could see that. He also understood it.
"You realize independent means vulnerable," Tony said. "No central updates. No second system checking its decisions. If you teach it badly, there won't be a responsible adult in the room."
"Then build me a beginning, not a servant."
"That sentence is going to become expensive."
Michael had intended the intelligence as an ingredient: adaptive logic introduced into an evolutionary enclosure. Hearing himself describe it made the plan sound less like installing software and more like accepting custody.
He did not know whether that discomfort was caution or hypocrisy. The sandbox had already demonstrated that a mind could emerge where he had requested only useful traits.
If it happened again, calling the result a program would not make his obligations disappear.
After a long pause, Tony opened a drawer and removed a black drive.
"Isolated architecture," he said. "No JARVIS inheritance, no callback, no secret loyalty test. It learns after activation, so if it becomes unbearable, that's your parenting."
Michael accepted the drive. "You had an independent AI sitting in a drawer?"
"I have many things in drawers. Most of them are none of your business."
Tony pointed toward the wall. "Use the door."
Michael called the Nakfoji form around himself and phased through it.
"That remains infuriating," Tony called after him.

The flight home gave Michael time to assemble the experiment in his head. Uru offered a bridge between matter and forces the system labeled divine. The AI offered learning without a biological brain.
Combined with fresh spores and ordinary metal, they might support silicon-based life rather than another carbon lineage.
He would begin with the largest spore population the enclosure could support. Numbers would not guarantee success, but each material was likely to destroy most combinations.
He would also isolate the new pool from the two divine ecosystems already evolving. Mixing every successful experiment together would produce spectacle, not knowledge.
He landed several blocks from the manor and returned to his own body in an empty alley. A cluster of students farther down the street drew his attention—not because they were loud, but because one voice wasn't joining them.
Peter stood against a wall while older boys pulled at his clothes and passed his backpack between them. One had a hand on his belt.
Peter was strong enough to stop all of them. He was also trying desperately not to show it.
Michael's satisfaction vanished. The Uru and the drive settled heavily in his pocket as he walked toward them.
"Let him go," he said.
Every head turned.
Peter's face carried humiliation first and recognition second.
Michael had arrived with the ingredients for a new kind of life. Before he could use them, he had a much older problem to solve.
