Cael had barely returned to the entrance chamber when the light changed again.
Not harsh, not cold—green. Faint, bioluminescent veins pulsed along the floor tiles like vines awakening beneath glass. The air felt... softer. Humid. Alive.

Incoming Vision Event…
Cael gritted his teeth, already recognizing the onset of a Core-induced memory feed. The world blurred, folded inward, and dropped him once more into another Architect's ghost.

He stood on soil.
Real soil.
The ceiling above was a massive dome carved from translucent stone, refracting soft blue light like a permanent sky. Around him, vertical gardens spiraled around stone spires, each building alive with plant growth.
No ruins. No steel.
Just... beauty.
A voice whispered—not in his mind, but as if someone stood beside him:
"Stone is not the enemy of life. It is its anchor."
He turned—no, his echo turned—toward a figure walking barefoot across a moss-lined path. Long robes of woven root fibers. Silver tattoos shaped like branching trees across their skin. The Architect known as Edena.
Her voice was patient. Gentle.
"We built walls, Cael Veren. We built them so high we forgot to breathe. And now we rot beneath them."
He felt himself respond—not in words, but in doubt. In resistance. The way the earth always pushes back against the shovel.
She smiled. Not unkindly.
"Your system has chosen survival. Mine chose renewal. But the Deep needs both. So take this—before survival becomes starvation."

The vision collapsed into light.
Cael gasped, one knee hitting the floor as the chamber returned to cold silence. The green glow faded, but a new icon shimmered in his interface:
[CORE FRAGMENT: EDENA – Partial]Category: Blueprint MemoryType: Living Infrastructure
Blueprint Unlocked – Mosswall Engine (Tier 1)Description: A passive wall segment that filters air, insulates temperature, and encourages fungal growth for food production. Non-defensive.
System Compatibility: Stable but Unaligned
He opened the blueprint.
No alloy. No concrete. Just growth mediums, shaped airflow, controlled humidity. And beauty—actual, intentional beauty.
It would be useless against attacks.
But it could heal a wounded community.
Cael sat against the wall and stared at the pulsing icon.
His system—Foundation—remained silent. Watching.
It wasn't angry. It didn't resist the integration. But it didn't like it either.
"Balance is weakness."The words weren't said. But he felt them.
He looked again at the Mosswall schematic.
Maybe it was weakness.Maybe it was a mistake.
But it was his to choose.
And if Hearthcore was to survive longer than a few Sparks, it needed more than walls and stabilizers.
It needed places that felt like home.
