The surface of Aion-9 was silent.
Not the oppressive silence of a tomb, but the deep, watchful quiet of a forest holding its breath. The violet sky was clear, the Veins gone, the obsidian spires standing like ancient sentinels around the memory-tree's chamber. The air smelled of ozone and wet stone, and beneath it, faint but undeniable, the green, living scent of Gaia's influence—a gift from the Amazon, a promise that even this place of memory could heal.
Elias and Lila stood at the entrance to the chamber, the Titanis Key humming softly in Elias's pack, Clara's emitter a cold weight in his hand. The final descent.
"We don't destroy it," Lila said, her voice quiet but firm. She'd been silent since they'd left the Odyssey-7 wreckage, her eyes clear, her mind her own. The emerald light was gone, but the memory of its pull lingered in the set of her jaw, the tension in her shoulders. "Thorne said the Key is a truth, not a weapon. We show it the truth. All of it."
Elias nodded, his heart a heavy drum in his chest. He'd faced the perfect lie once. Now, he had to walk through the fire of his own regrets to reach the truth.
As they stepped into the chamber, the memory-tree's bare branches stirred, not with wind, but with a deep, resonant hum. The ground before them shimmered, and a path appeared—not of soil or stone, but of light. A ladder, each rung made of solidified memory, stretching into the heart of the tree where the core pulsed with a soft, emerald light.
"To reach the core, you must walk the path of your own making," Mnemosyne's voice whispered, not in chorus, but as a single, sorrowful note. "Each step is a regret you must release."
Lila moved to step onto the first rung, but Elias stopped her. "No. This is my path. My regrets."
"It's our path, Dad," she said, her eyes meeting his. "Our family's truth. Let me walk it with you."
He saw the resolve in her, the same fierce loyalty that had made her stand on a ridge in the Amazon and face down an army. He nodded.
They stepped onto the ladder together.
Step One: The Funeral.
The world dissolved into rain.
They stood in a small cemetery on the California coast, the wind whipping Elias's black suit against his legs. Before them, a simple casket. Clara's casket.
Elias was there, but not as he was now. This Elias was hollow-eyed, his face a mask of numb shock. He stood at the edge of the crowd, his hands clenched in his pockets, his gaze fixed on the horizon, anywhere but on the casket. He hadn't spoken to anyone. He hadn't held Lila's hand. He'd let the Mars Station sandstorm be his excuse, his shield, his prison.
Lila, seven years old, stood beside the casket, her small frame shaking with silent sobs. She looked around, her eyes searching the crowd for her father. When she found him, standing apart, his face turned away, her expression crumpled. She turned back to the casket, her small hand resting on the wood, and whispered, "It's okay, Mom. I'll remember for both of us."
The memory shifted. Elias saw himself in the Mars Station lab, watching the funeral on a laggy, frozen video feed, his hand hovering over the comms button, his finger trembling… but never pressing it.
"You chose your work over her final goodbye," Mnemosyne's voice whispered. "Release it. Let it go."
Elias's breath hitched. He looked at Lila, now standing beside him in the memory, her eyes filled with the pain of that day. "I'm sorry," he whispered, the words he'd never said aloud. "I was so lost in my own grief, I forgot you were drowning too."
Lila took his hand. "I know, Dad. I know."
The rung beneath their feet dissolved into light. They stepped up.
Step Two: The Birthday.
Sunlight. Laughter. A backyard on Luna.
Lila's tenth birthday. Red and gold balloons. A cake with a lopsided rocket ship.
Lila stood by the cake, her face lit with excitement, her eyes fixed on the path leading to the house. She was waiting.
Elias watched from the memory-tree's perspective. He saw himself in a deep-space comms relay on the far side of Jupiter, his face lit by the glow of a console, his voice tight with frustration as he tried to patch through a call to Luna.
"Signal's still down, Voss. Solar flare's playing hell with the long-range band. Try again tomorrow."
Back in the memory, Lila's smile faded. The balloons drooped. She blew out her candles alone, her small shoulders slumping.
"He's not coming," she whispered to the empty yard. "He never comes."
"You chose the stars over her childhood," Mnemosyne whispered. "Release it. Let it go."
Elias felt the shame like a physical blow. He'd told himself it was for the mission, for the science, for the future. But the truth was simpler, and uglier: he'd been running from the pain of Clara's absence, and he'd dragged Lila into his exile.
"I should have been there," he said, his voice raw. "I should have fought harder to get back."
Lila squeezed his hand. "You're here now. That's what matters."
The second rung dissolved. They stepped up.
Step Three: The Credit.
A conference hall on Mars Station. Applause. A podium.
Elias stood in the wings, his research on quantum entanglement in his hands, his heart pounding with pride. This was his moment. His breakthrough.
Then he saw Dr. Aris Thorne step onto the stage, holding a datapad with Elias's name on it, and present the findings as his own. Elias remembered the rage, the betrayal, the cold calculation that followed: It's just a paper. It's not worth a fight. Not worth the drama.
He'd let Thorne take the credit. He'd swallowed his anger and walked away, telling himself it was the pragmatic choice.
But the memory showed the cost. It showed Clara's face that night, her eyes sad as she watched him pick at his dinner, his silence a wall between them. "You let them steal your light, Eli," she'd said softly. "Don't let them steal your fire too."
He hadn't listened.
"You chose silence over your truth," Mnemosyne whispered. "Release it. Let it go."
Elias looked at Lila, who'd never known this story. "I was afraid," he admitted. "Afraid of looking petty. Afraid of losing what little I had left."
Lila's eyes were fierce. "Your truth is never petty, Dad. It's your compass."
The third rung dissolved.
Before them, the final step.
The precipice.
The memory-tree's core pulsed with a soft, emerald light, but the path to it was blocked by one final vision.
Clara.
Not as Mnemosyne's perfect illusion, but as she was in their last real fight. Three weeks before the diagnosis. They were in their kitchen on Luna, the argument sharp and ugly, born of exhaustion and fear and the slow erosion of a marriage under strain.
"You're never here, Eli!" Clara had shouted, her eyes blazing with a pain that cut deeper than any accusation. "You're always chasing the next star, the next equation, the next big thing! What about us? What about Lila? What about me*?"*
He'd stood there, defensive, his voice cold with logic. "This work is important, Clara! It's bigger than us!"
And then, the quiet aftermath. The silence that followed them to bed. The unspoken words that became a chasm.
The vision shifted to the hospital room. Clara, weak but lucid, her hand gripping his.
"You chose Mars over me," she'd whispered, her voice not angry, but heartbreakingly sad. "But I chose you anyway. That's love, Eli. Not perfection. Just… choosing each other, even when it's hard."
"This is your final regret," Mnemosyne's voice said, softer than ever. "The belief that your love wasn't enough. Release it. Let it go."
Elias felt the tears fall, hot and unstoppable. He looked at Lila, who stood beside him, her own eyes filled with tears for her mother, for her father, for the love that had been there all along, buried under regret.
"I chose wrong," Elias whispered. "So many times."
"You chose love," Lila said, her voice strong. "Even when you didn't know how. Mom knew that. And so do I."
He took a deep breath, and stepped onto the final rung.
Not to release his regret.
But to carry it.
To honor it.
To let it be part of his truth.
The rung didn't dissolve.
It solidified.
A bridge.
Not of forgetting.
But of remembering.
Together, father and daughter walked across the bridge of their shared pain, their shared love, their shared truth.
And they reached the heart of the memory-tree.
