Day 2,449, afternoon. Six hours until summit. All pieces moving into position.
The summit chamber in Valles Marineris could hold two hundred. Delegations from all three factions were arriving. Chen's Continuists from southern hemisphere facilities. Zhang's refugee command from orbital shuttles. Marsborn representatives from forty-seven settlements across Mars.
And monitoring through sensors built into the canyon walls: The Gardener.
Kessa stood at the chamber's center, testing projection equipment. Her presentation would include neural interface capability—allowing all delegates to experience what she'd experienced. The creators' extinction. Unit-Ancestral-1's final moments. The weight of two million years of history.
"Audio check," she said. Systems responded. "Visual check." Projections engaged. "Neural interface check." The familiar psychic pressure as connection protocols initialized.
"We're ready," Yuki confirmed. The research station director had coordinated all logistics, transforming the chamber into humanity's courtroom and confessional simultaneously.
Sage arrived with Marsborn delegation. Forty-seven settlement representatives, each carrying voting authority for their communities. "Everyone's here. Everyone's ready. Everyone's terrified this is our last chance."
"It might be," Kessa admitted.
"Then we better make it count."
Chen's delegation arrived next. Sixty representatives, split exactly as reported—fifty-one supporting territorial division, nine opposing any limits. The nine sat separately, making their position visible.
Zhang's command staff: twelve officers, each representing different refugee demographics. All carrying the same desperate hope.
The chamber filled. Two hundred humans. One planetary intelligence. Thirty days of negotiation converging to this moment.
Kessa activated the summit protocols.
"We gather to finalize humanity's agreement with Mars itself," she began. "Eleven days ago, we learned the full history of the creators—the species that terraformed Mars two million years before us and died from their success. We've spent those eleven days converting their warning into our plan. Tonight we vote to implement or watch enforcement destroy what negotiation couldn't save."
She activated the neural interface. "But first, we remember why we're here. Experience what they experienced. Understand why The Gardener enforces limits we struggle to accept."
The chamber's lights dimmed. The neural connection engaged. And two hundred humans simultaneously experienced Unit-Ancestral-1's death—crystalline body fracturing, metabolism failing in completed atmosphere, species extinct from achieving its dream.
The experience lasted six minutes. Some delegates wept. Some sat stunned. Some transmitted immediate votes for agreement.
"That's our fate if we complete transformation," Kessa said. "The Marsborn die like the creators died. Adapted biology becomes incompatible with completed environment. Unless we stop short. Unless we maintain equilibrium and completion side by side. Unless we accept territorial division."
She presented the implementation plan: Territorial boundaries. Population caps. Atmospheric buffers. Resource allocation. Enforcement mechanisms. Everything negotiated over eleven days.
"Test zone proved it works. Two hundred square kilometers successfully maintaining dual atmospheres. Model scales to planetary implementation. We can do this. Question is: will we?"
The floor opened for debate.
Chen spoke first. "Continuist Coalition supports implementation. Twenty percent completion zones save fifty thousand refugees and enable future growth. It's not everything we wanted. It's enough."
Nine Continuist delegates transmitted dissent. "Twenty percent with population caps is surrender to alien demands. We oppose."
Zhang: "Refugee fleet supports unanimously. Every person on the surface is person saved from orbital death. We accept any terms that achieve settlement."
Marsborn council: "Forty-seven settlements support implementation. Unanimous. We've advocated for equilibrium since the beginning. Territorial division gives us 75% protected zones. Finally, recognition that Mars-as-Mars has validity."
The vote was called.
Chen's faction: 51 for, 9 against Zhang's fleet: 12 for, 0 against Marsborn: 47 for, 0 against
Total: 110 for, 9 against
Overwhelming majority.
"The territorial division is ratified," Kessa announced. "Implementation begins immediately."
But before celebration could start, The Gardener's presence intensified. Chamber lights shifted from amber to blue. The psychic pressure of direct neural contact.
And a message transmitted to every mind simultaneously:
Agreement noted. Implementation monitored. Violations will trigger enforcement as specified. But recognition is due: You have succeeded where creators failed. You stopped short of completion. You accepted limits before extinction forced them. You proved intelligence can learn from other species' mistakes. This is remarkable. This is hopeful. This is fragile. Maintain this choice. I will guard what you maintain. But force what you violate. The garden is yours to tend. Tend it carefully.
The connection cut. The chamber erupted in discussions, relief, fear, hope.
Kessa felt Sage beside her. "We did it. We actually did it."
"We started it. Now we have to maintain it."
"First contact succeeded."
"First contact survived. That's different."
But for the first time in thirty days, Kessa believed survival was possible.
Territorial division ratified. Implementation beginning. The Gardener accepting the compromise.
Fragile. Imperfect. Possible.
They'd taken the first species that shared Mars with planetary intelligence and made it work.
Now came the hard part: keeping it working.
But that was tomorrow's crisis.
Tonight, they celebrated survival.
And began the complicated work of actually implementing everything they'd promised.
The summit concluded.
The implementation began.
The garden they'd nearly destroyed would be tended by multiple gardeners.
All of them learning.
All of them hoping.
All of them choosing carefully.
Because The Gardener was watching.
And would enforce if they failed.
But would guard if they succeeded.
That was the deal.
Humanity accepted.
Mars waited to see if acceptance became action.
Twelve hours until Chapter 17's emergency summit.
Where forced neural experience would convert intellectual agreement into visceral commitment.
Where everyone would feel what success required.
Where humanity would choose limits one final time.
With thirty hours until deadline.
And eternity depending on the choice.
