The cathedral was quiet when Leximus woke.
He had slept on the cot in the side chamber, the Memory-Knot chain in its wooden box beside him, the void-altar pulsing in the distance. The cold inside him was steady now—not the flickering uncertainty of before, but something settled. Something that had made peace with itself.
He sat up slowly. His neck ached where the needle had pierced, but the Tide-Mark was different. The black lines had shifted, no longer just marks on his skin. They seemed deeper now, as if they had always been part of him and he had only just noticed.
Eugene sat on the bench across from him, a cup of tea in his hands. The steam rose in thin curls, disappearing into the darkness above.
"You've been asleep for two days," Eugene said.
Leximus blinked. "Two days!?"
"The integration took more out of you than I expected. Your body needed time to adjust." Eugene set the cup aside. "How do you feel?"
Leximus stood. His legs were steady. His head was clear. The cold inside him was quiet, patient.
"Different," he said. "I feel different."
"Good. That's the integration settling." Eugene stood. "Come. There's something I want to show you."
Eugene led him to the main chamber, where the void-altar pulsed in the darkness. The Lumen of the Forgotten had been moved here, its pale flame casting strange shadows on the walls. The Mare's Tear was gone—returned to the spring beneath the old city. The voidglass sat on a small table beside the altar, dark and cold.
"Echo-Walk," Eugene said. "That's what the integration gave you. The ability to step into a location's memory layer and see its past."
"Really, then how does it work?"
"I don't know. No one has ever had this power before." Eugene gestured to the wall. "Try it. Focus on the stone. Feel its history."
Leximus walked to the wall. The stone was cold beneath his palm. The cold inside him stirred, responding to something beneath the surface.
Memory is potential, he thought. The past is a shadow of what could have been.
He closed his eyes.
The world shifted.
He was no longer in the cathedral. He was standing in a cave—the same cave, but different. The walls were rough, uncarved, untouched by centuries of hands. The void-altar was not there. Instead, a spring bubbled up from the floor, clear and cold, its water reflecting a sky that didn't exist.
A woman knelt by the spring. She was young, her hair dark, her hands calloused. She wore robes that Leximus didn't recognize—simple, undyed, the kind of clothing that predated the Church's vestments.
She was praying.
Not to the Sources. To something older. Something that had no name.
Blessed is the Void, she whispered. For it is the space in which all things become possible.
Leximus watched her. She couldn't see him. He wasn't really here. He was in the memory layer, an echo of what had been.
The woman stood. She dipped her hands in the spring, raised them to her lips, and drank. The water glowed faintly as it passed her throat—a light that came from within, not from without.
She was the first. The first Avatar to drink from the Void's well. The first to understand that potential was not something to be feared, but something to be embraced.
The vision faded.
Leximus opened his eyes.
His hand was still pressed against the stone. The cold inside him was pulsing, faster than before, as if excited by what he had seen.
"How long was I gone?" he asked.
"Three seconds," Eugene said.
Leximus looked at the wall. The stone was still there, still solid, still real. But he had seen what lay beneath. He had touched the memory of the first Avatar, the one who had built this cathedral before the Church existed.
"Echo-Walk," he said. "It's not just seeing the past. It's living it."
"Yes." Eugene's voice was soft. "That's why it's dangerous."
Eugene led him back to the side chamber and sat him on the cot.
"The integration gave you a power that shouldn't exist," Eugene said. "Shadow and Water are not meant to mix. Echo-Walk is a grafted thing—a hybrid. It will cost you every time you use it."
"What kind of cost?"
"Pain. Exhaustion. Corruption. The more you use it, the faster the Tide-Mark will spread." Eugene paused. "If you use it too much, the integration will fail. The Water and Shadow will start fighting again. And this time, there won't be a ritual to save you."
Leximus looked at his hands. The black lines had spread slightly—not much, just a fraction, but enough that he could see the difference.
"How many times can I use it?"
"I don't know. No one has ever had this power before." Eugene's voice was firm. "But I know this: every time you use Echo-Walk, you are borrowing time. Borrowed time must be repaid."
Leximus nodded.
He thought of the woman by the spring. The first Avatar. The one who had drunk from the Void's well.
She had paid a price too. He could see it in her eyes, in the way she had moved, in the weight of her prayers. She had given something to the Void, and the Void had given something back.
Everything the Void gives, it takes back, he thought. That's the nature of potential.
He stood.
"I need to practice," he said. "I need to understand what I can do."
"Be careful."
"I'm always careful."
Eugene's face was unreadable. "No. You're not."
Leximus walked to the far end of the cathedral, where the walls were oldest, the stone worn smooth by centuries of hands. He pressed his palm against the surface and closed his eyes.
The vision came faster this time.
He was standing in a corridor—narrow, dark, lit by torches that guttered in the damp. Men in robes ran past him, their faces pale, their hands clutching scrolls. Behind them, the sound of boots on stone. The Church had come. The purge had begun.
The first Avatars were fleeing. Not because they were cowards—because they needed to survive. They needed to hide. They needed to keep the Void's knowledge alive.
Leximus watched them run.
He wanted to help. He wanted to tell them where to go, how to hide, how to survive. But he was just an echo. A memory of a memory. He couldn't change the past. He could only witness it.
The vision faded.
He opened his eyes. His head ached. The cold inside him pulsed, slower than before, as if tired.
"How long?" he asked.
"Five seconds," Eugene said. "You're getting better."
Just then he felt a sharp sensation penetrate his skull. He touched his forehead with the tips of his fingers. "It hurts."
"Good. That means you're paying attention."
