Chương 97: The Resonance Node

That night, after Domrek took first watch, Kaito went below with the key. He sat on the bunk. Closed his eyes. Thought about the door. The ship dropped away. The corridor came back — dark walls, dense writing, the light that came from text itself. He walked the bright direction. The round room opened up, Hana's handprint on the pedestal, the walls alive with layered script. He put his hand on the handprint. The room lit up.

'All right,' he said.

'Show me what the key can read from here.' He held the key out in front of him and opened his Sight. The walls dissolved. Not literally. They went transparent. Behind them was — more. Architecture. The substrate layer spreading out in every direction, dense and mapped and enormous. Kaito had read small pieces of it before — individual skills, individual structures. This was the whole thing. The full grid.

The world's infrastructure laid out in front of him like the wiring diagram for a building the size of a continent. He couldn't read most of it. Too dense, too old, too many layers. But the major lines were visible — thick channels of registration running between five points, evenly spaced, pulsing with slow regular energy like a heartbeat. Five nodes. Five Resonance Nodes. He'd designed them. He knew where they were supposed to be. Verath. Noxara. Solketh. Aethros. The Silent Reaches.

The Verath node was the closest to something he recognized. It sat under the Tower of Beginnings — the starting spire, the first place he'd opened his eyes in this world. He'd built a city around it in the game because the location felt important. He'd written in the design docs: 'infrastructure of unknown Precursor type, left intact, do not specify.' He reached for it with the key. Something happened. The node responded. Not with words. With data.

A flood of it — registration numbers, power readings, throughput values, connection statuses. The key translated it into numbers he could read, and the numbers were wrong. The Verath node should have been running at full capacity. It was the central node, the anchor of the whole grid, the one the other four drew from and fed back into. According to the Precursor design specs that were baked into the substrate, its nominal output was a number Kaito didn't have a frame of reference for. Big. Very big.

Enough to power every System function across the central continent. Current output: eleven percent. He stared at it. Eleven percent. The central node of the world's power grid was running at eleven percent of capacity. He reached for the next one. Noxara. Deep sea. The Thalassian Dominion sat on top of it — he knew that from the archive in Velhen. Noxara: eight percent. Solketh. Inside the volcanic caldera. The Emberborn guarded it. Solketh: fourteen percent. Aethros. The sky continent, twelve kilometers up.

The Aethrian Conclave studied it. Aethros: six percent. The Silent Reaches. Polar. The last one. He reached for it and hit a wall. Not a wall of data. An absence. The node read as — present but dark. Like a light that was on but producing nothing. Zero output. Not broken. Drained.

'Zero,' Kaito said, out loud, to the empty room.

'The Silent Reaches node is at zero.' He pulled back and looked at the whole grid at once. Five nodes. Total capacity: whatever the Precursors had built this thing to produce. Current total output across all five: thirty-nine percent. And falling. The numbers had a drift to them — they were lower now than they had been a year ago, and lower a year ago than two years before that. The drain was steady. Systematic. Not a failure. A draw. Something was pulling the power out of the grid. He followed the draw.

It wasn't hard. The substrate showed energy flow the way a topographic map showed water — it ran downhill, toward the lowest point. The lowest point in the grid was the Silent Reaches node. Zero output. Everything flowing toward it and vanishing. Not vanishing. Being consumed. There was a signature on the draw — a registration tag, old and partially corrupted, sitting in the data stream the way a name sits on a utility bill. Kaito couldn't read the full tag. Part of it was in a script he didn't know.

Part of it was in a script he did. The part he could read said one word. He pulled his hand off the pedestal. The room dimmed. The grid disappeared. The walls went back to being walls. Unlawfully taken from Royal Road, this story should be reported if seen on Amazon.

'One word,' he said. His voice was flat. He knew the word. He'd written it on a Sunday afternoon in a kitchen in Tokyo because he needed a name for the big bad. He'd picked it from Greek mythology because it sounded right. The primordial darkness. The void between things. Erebus. The corridor pulled him back. The dark end swallowed him. The ship came back — the rocking, the creak, the cold salt air. He opened his eyes. Pell was sitting on the opposite bunk, eating an apple and watching him.

'You were out for twenty seconds this time,' Pell said.

'Less twitching than last time. Eyes moved more though.'

'Where's Domrek.'

'On deck. I told him I'd sit with you.' Pell took another bite.

'You look like you found something bad.'

'Yeah.'

'How bad.'

'The world runs on five power nodes,' Kaito said.

'They're almost empty. Something has been draining them for years. I found out what.' Pell chewed. Swallowed. Looked at him.

'The thing under Velhen,' Pell said.

'How did you guess that.'

'I didn't guess,' Pell said.

'I've been paying attention. You said its name the night we found it. You said it again on the road. Every time you say it, your face does a thing.' He set the apple core on the bunk.

'Is it the kind of problem that has a fix, or the kind that just has a speed.'

'I don't know yet.'

'Find out,' Pell said.

'Then tell me which kind, and I'll plan accordingly.' He stood up.

'I'm going to go tell Domrek you're alive and that something's wrong. He'll want the details from you, not from me.'

'Pell.'

'Yeah.'

'Thank you for sitting with me.'

'Somebody has to,' Pell said.

'You keep going to places your body doesn't go. That's the kind of thing that needs a man with an apple in the room.' He went up the ladder. Kaito sat on the bunk. The key was warm in his hand. The numbers were still in his head — eleven, eight, fourteen, six, zero. Thirty-nine percent total. Draining. Erebus at the bottom of the funnel, pulling it all toward the Silent Reaches.

'Sable,' he said. Nothing. She'd said she couldn't follow him into the room. Had she come back?

'Sable.'

'I'm here,' she said.

'I was waiting. I could feel you leave and come back. I could not see where you went or what you found.'

'I found the Resonance Nodes.'

'All five.'

'All five. They're dying. Total output across the grid is thirty-nine percent and falling. The Silent Reaches node is at zero. Erebus is draining them. His signature is on the draw.' Sable was quiet for three full seconds. That was a long time for her.

'How long has the drain been active,' she said.

'Years. The data shows a steady decline. I didn't have time to calculate the exact start, but from the curve it looks like — maybe ten years. Give or take.'

'Ten years,' Sable said.

'Yeah.'

'Ten years ago is when Hana left Tessara's island.' Kaito hadn't put that together. He put it together now.

'You think those are connected.'

'I think Hana knew,' Sable said.

'I think she knew the drain had started, and I think she left because of it. She built the workspace. She built the key. She left a message with Tessara. She set up everything you needed to find what you just found. And then she left.'

'Why not stop it herself.'

'I don't know,' Sable said.

'That is the question I cannot answer and it is the one that matters most.'

'If Erebus drains the grid to zero,' Kaito said.

'What happens.'

'AXIOM loses its power source,' Sable said.

'The System stops. Not immediately — there are reserves, buffers, redundancies. But eventually. The registration layer goes dark. The skill system stops calculating. The class notations stop updating. Every piece of infrastructure that AXIOM manages stops being managed.'

'Everything.'

'Everything,' she said.

'Levels. Skills. Notifications. Quest markers. Monster behavior templates. Dungeon logic. Resurrection mechanics. All of it runs on the Resonance grid. All of it stops when the grid stops.'

'How long at the current rate.'

'I need the numbers you pulled to calculate,' she said.

'But if the drain has been running for ten years and the grid is at thirty-nine percent — roughly. Years, not decades. Single digits.' Kaito breathed out.

'We have years,' he said.

'Yes. But Erebus has been doing this for ten already, and nobody noticed until you walked into that room five minutes ago.' A pause.

'Which means he is very good at this. And very patient. And he is almost certainly ahead of any schedule we can estimate from the outside.' Domrek came down the ladder. He ducked under the low beam and stood in front of Kaito's bunk.

'Pell said you found something,' he said.

'Sit down,' Kaito said.

'This is going to take a minute.' Domrek sat. Kaito told him. All of it. The five nodes. The numbers. The drain. Erebus's signature at the bottom. What happens if the grid hits zero. Domrek listened without interrupting. When Kaito finished, Domrek sat with it for about ten seconds.

'So the thing you designed as the final boss,' Domrek said, 'is eating the world's battery. And when the battery dies, everything stops.'

'That's the short version.'

'What's the plan.'

'I don't have one yet.'

'Then get one,' Domrek said.

'You've got the key. You've got the room. You've got an eight-hundred-year-old historian upstairs and a voice in your head who's lived in the walls since before the System existed. Use them.'

'I plan to.'

'Good.' Domrek stood up.

'I'm going to go tell Tessara. She'll want to hear the numbers. She's been alive long enough to know what a declining power curve looks like.' He went up the ladder. His boots were heavy on the rungs and then gone. Kaito sat in the dark of the cabin with the key in one hand and the other hand flat on his knee.

'Sable,' he said.

'One more thing.'

'Yes.'

'Hana knew about the drain ten years ago. She built me the tools to find it. She set up Tessara to deliver them. She planned all of this. But she didn't stop Erebus herself. She left that for me.'

'Yes.'

'Why.'

'I have a theory,' Sable said.

'I'm not ready to say it yet.'

'When.'

'When I understand why she built a room I can't enter,' Sable said.

'Those two facts are connected. I can feel it. I just can't see the shape yet.' Kaito nodded in the dark. Above him, on deck, he heard Tessara's voice say one word — a number, probably, repeated back to Domrek. Then silence. Then footsteps. Coming back down the ladder. Tessara's, lighter than Domrek's. She appeared at the bottom of the ladder and looked at him.

'The First Calamity,' she said.

'The one I was going to tell you about tomorrow evening.'

'Yeah.'

'It was a node failure,' Tessara said.

'Three thousand years ago. The proto-Noxara node was drained to zero. The continent broke apart. The sea came in. That is what zero looks like.' She looked at him.

'We should talk,' she said.

'Now. Not tomorrow.'
