Normal temperature did not restore the genetic sandbox. It changed the terms of survival again.
Michael watched meltwater divide the enclosure into shallow sea and exposed land. The descendants of Nakfoji multiplied quickly. Each could produce at least five offspring, and their long lives turned success into crowding before they developed any answer to it.
Food thinned.
Their bodies remained strong. Their society did not become wise to match.
The surviving line remembered cold as safety. As the glaciers receded, the strongest gathered around the frozen apple tree. They used their breath to preserve the ground beneath it and raised an ice temple around the memory of Nakfoji.
Maintaining the temple became a measure of worth. Those with the strongest cold gathered inside and worked little beyond renewing the walls. Everyone else searched farther for food and carried it back.
Michael leaned over the boundary, seeing the pattern even when he could not hear the arguments at their scale.
"You need farming," he muttered. "Or distribution. Preferably before someone discovers slogans."
The lineage discovered revolt first.
Workers abandoned their routes and moved against the temple. Frost from the elite ranks swept over them. The uprising ended so quickly that, from Michael's side of accelerated time, it looked like a pale ripple across the ground.
The dead went beneath the soil. Survivors returned to work, then rebelled again. Strength still determined status, and hunger still belonged to those outside. Each failed revolt added another layer of remains under the thawing land.
When the hierarchy finally collapsed, war and starvation had left too few survivors to divide into rulers and laborers.
They gathered beneath the frozen apple tree because every other institution had failed them.
Michael had wanted a useful adaptation. He had produced a civilization, watched it discover exploitation, and learned that accelerated time could make an atrocity look efficient.
Movement stirred beneath the burial ground.
The system did not identify it. Not yet.
Michael waited, but the television in the next room pulled his attention away. A live report showed storm clouds, armed personnel, and a hammer no one at the restricted site could move.
Thor.
The god had lost his power, if Michael remembered the story correctly. That still made him an Asgardian with blood, hair, and cells worth more to the genetic sandbox than any ordinary sample Michael could obtain.
Michael took his bearing from the storm above the site; the Nakfoji form could cross the distance without roads.
He wanted the biology, not the hammer. Divine power might vanish with whatever judgment had brought Thor down, but the body left behind was still Asgardian.
A sample could reveal whether the system found that inheritance stable, impossible or lethal. Michael wanted the answer before another god arrived with less patience.
"A tube of blood," Michael said. "How difficult can that be?"
The universe had punished that sentence often enough to make it tradition.
He called up the Nakfoji form. Blue armor replaced skin, wings opened behind him, and the ground released its claim. Michael rose toward the darkening sky and left the enclosure behind.

Beneath the soil, something awoke without knowing what it was.
It had no mother. No tribe called to it. It possessed only fragments: the pressure of bodies above, the bitterness soaked into the ground, the final terror of creatures whose deaths had not ended cleanly.
The thing drifted through the burial layers as a pale outline.
Why am I here?
The question did not arrive in words at first. It was an emptiness shaped like a question.
Other phantoms moved through the earth. The new consciousness rushed toward the nearest one, desperate for recognition. At contact, the phantom dissolved.
Part of it remained.
Memory entered without a life around it: hunger, labor, cold walls, the flash of a stronger creature's breath. The consciousness recoiled, then reached for another.
That one dissolved, too.
Each contact left the wanderer more solid and more alone. Companions became substance before they could become company.
It searched anyway.
Loneliness accumulated with the dead. So did resentment. The feeling gained tentacles, pale skin, purple eyes, and an inverted face that reflected none of the creatures from which it had formed.
When it reached the abandoned ice temple, murals along the walls gave order to the memories inside it. They showed Nakfoji. They showed the first descendants. They showed rulers above and workers below, followed by frost, revolt, and burial.
It chose a name—Iktori—and gave its anger a speaker.
"You destroyed your own people," Iktori told the painted founders. "I will not forgive you."
It did not understand that Nakfoji had died before the society in those murals existed. Hatred did not require accurate history. It required a target.
Iktori felt the scattered dead within itself and discovered that assimilation was more than appetite. As long as those fragments remained joined to it, extinction could be refused. One body could become the beginning of a people.
Aboveground, the last descendants had crowded together beneath the apple tree. Their former strength had faded with the warming world. Freezing breath that once decided rank now produced little more than a brief crust over wet soil.
As the second night approached, Iktori rose through the earth toward them.
"Wait for me," it whispered. "I will liberate you."
The first descendant to sense it turned toward empty ground. A chill moved through the gathered bodies, but this cold did not come from weather or breath.
It carried the memory of revolt. Creatures born after the massacres felt fear they had never learned.
They drew closer together.
The soil darkened at the edge of the frozen roots. Tentacles passed through it without disturbing a grain. Purple eyes opened below an inverted pale face and looked upon the survivors as if they were both family and accusation.
No one attacked.
For one suspended moment, the remnant of Nakfoji's lineage and the thing made from its dead recognized that the world contained someone else.
Then night settled over them.
***
Far from the manor, Michael flew through colder air.
The Nakfoji form should have felt clean and simple: wings, speed, the pressure of distance sliding across his sensory horns. Instead a tear gathered beneath one blue eye.
Wind tore it away before he could touch it.
Michael banked, unsettled by an emotion that had no obvious cause. He was not sad. At least, he had not been a moment earlier.
The system had given him instincts with the form. It had never promised a clean boundary between instinct and memory.
The tear might come from fatigue, the sandbox's changing climate or an echo without a name. Calling it Nakfoji's grief would be comforting, but Michael had no evidence for it.
Below him, roads stretched toward the storm and the fallen hammer.
"Was that mine?" he asked the empty sky. The form offered no answer, and neither did the dead founder whose shape Michael wore.
