Tuesday morning. Six forty seven AM.
Lee Soo-Bin was at the third Gate residue site of his morning cleanup session when his constellation went very quiet.
Not the attentive quiet.
Not the monitoring quiet.
The specific quiet of something that is watching something it has never seen before and is not sure how to describe it.
Lee Soo-Bin looked up from the residue site.
At the sky.
"What is it," said Lee Soo-Bin.
The constellation's response was not in images or feelings this time.
It was a direct impression.
A single concept delivered with the full weight of something that has been watching the space between stars for longer than most worlds have existed.
The concept was: approaching.
"What is approaching," said Lee Soo-Bin.
The very strange world.
Lee Soo-Bin stood up from the residue site.
Looked at the eastern sky.
Nothing visible.
"The very strange world is approaching," said Lee Soo-Bin. "How."
Through the clean energy.
"Through the Dragon Vein network."
Yes. It is following the clean energy. The same way the very large world's entity followed it to Seoul. The very strange world felt the clean energy and it is coming toward the source.
"How large is it," said Lee Soo-Bin.
A long pause from the constellation.
The pause of something searching for an adequate comparison.
Small, said the constellation. For what it is.
Lee Soo-Bin called Han-Ho.
Han-Ho was at drain six of the Tuesday northern section.
He read the drain.
Made the completion note.
Filed it.
His phone buzzed.
Lee Soo-Bin.
"Han-Ho."
"Yes."
"The very strange world."
"Yes."
"Something is coming through the Dragon Vein network."
Han-Ho made a note.
"Following the clean energy," said Han-Ho.
"Yes. The constellation says small for what it is."
"What is it," said Han-Ho.
"Unknown," said Lee Soo-Bin. "The constellation cannot describe it. Not because it is threatening. Because the very strange world does not have categories that translate cleanly into any other world's framework."
"Arrival time," said Han-Ho.
"The constellation says—" A pause. "The constellation says it is already here."
Han-Ho looked at the drain.
At the Tuesday morning Mapo district.
At the ordinary city doing its ordinary things.
"Where," said Han-Ho.
"The constellation says—" Another pause. Longer. "The constellation says it is at the cleanest point on your route."
Han-Ho thought about this.
The cleanest point on the route.
He had been running the route for ten years.
He had been cleaning it systematically for ten years.
He had been augmenting it with the shard for several weeks.
He knew every point on the route.
He knew which section had the highest ambient Dragon Vein quality.
He knew exactly where the cleanest point was.
He looked at drain six.
Looked at the ground around drain six.
Pressed his hand against the surface.
Read it.
There.
Not in the Dragon Vein network.
Not in the between-layer.
On the surface.
Something very small.
The size of a large coin approximately.
Sitting on the pavement next to drain six.
He had not noticed it because it was the same color as the pavement.
Not exactly the same color.
But close enough that at a casual glance it was invisible.
"Lee Soo-Bin," said Han-Ho.
"Yes."
"It is at drain six."
"At drain six," said Lee Soo-Bin.
"Next to it yes. On the pavement." Han-Ho pressed his hand more firmly. "It is very clean. Cleaner than the shard in some respects. Different clean. The shard is source energy clean — the original quality. This is—" He read more carefully. "This is a different kind of clean. Not source. Achieved."
"Achieved clean," said Lee Soo-Bin.
"Yes. Something that worked very hard to become clean. That has been trying to make clean energy its entire existence. That has just now succeeded for the first time." Han-Ho made a note. "It followed the clean energy through the Dragon Vein network to the cleanest point it could find. And it stopped here."
"It stopped next to drain six," said Lee Soo-Bin.
"Yes."
"In the Mapo district."
"Yes."
"On a Tuesday morning."
"Yes," said Han-Ho. "Filing report."
He filed it.
Looked at the thing next to drain six.
The very strange world's visitor.
The size of a large coin.
The color of pavement.
Sitting still with the patient quality of something that has traveled a very long way through a dimensional energy network and has arrived exactly where it was trying to arrive and is now waiting to see what happens next.
Han-Ho looked at it for a long time.
The thing looked back.
He had no sense of eyes or face or expression.
It was just a shape.
A small shape.
Very clean.
On his road.
"You came through the Dragon Vein network," said Han-Ho.
No response in Dragon Vein pulses.
No sound like Cheongi.
No ambient communication like the ley line network.
No energy translation like the entity from the very large world.
Nothing familiar.
Just the thing sitting on the pavement next to drain six.
Han-Ho pressed his hand against the pavement adjacent to it.
Read the energy around it.
Made notes.
"The energy quality around it," said Han-Ho to Min-Seo who had arrived behind him.
"Yes," said Min-Seo.
"It is not just clean," said Han-Ho. "It is trying to be clean. Still trying. Right now. It arrived and it is still actively working on becoming cleaner." He made a note. "It has never stopped."
Min-Seo looked at the thing.
At the coin-sized visitor from the very strange world sitting next to drain six on a Tuesday morning in Mapo-gu.
"It is still working," said Min-Seo.
"Yes," said Han-Ho. "It does not know how to stop. It has been trying to make clean energy its entire existence. Clean energy is what it has been trying to produce. It does not have a concept of clean being a finished state." He made more notes. "For the very strange world clean is not something you achieve. It is something you do. Continuously."
Min-Seo looked at Han-Ho.
"That sounds familiar," said Min-Seo.
Han-Ho was reading the surface adjacent to the visitor.
"Yes," said Han-Ho. "The route does not finish. The cleaning continues. Clean is not a state you arrive at and stay in. It is work you do every day."
Min-Seo looked at Han-Ho.
At the visitor.
At Han-Ho.
"Han-Ho," said Min-Seo.
"Yes."
"The very strange world sent something to find the source of the clean energy."
"Yes," said Han-Ho.
"And it found drain six."
"Yes."
"Of the Mapo district northern section."
"Yes."
"On a Tuesday morning."
"Yes," said Han-Ho.
"Because drain six is the cleanest point on the route right now."
"Yes," said Han-Ho.
"Because you cleaned it."
"Yes."
"Because you have been cleaning it for ten years."
"Yes," said Han-Ho.
Min-Seo looked at the visitor.
At the coin-sized thing from a world that had no concept of clean and had been trying to make clean energy its entire existence and had followed the Dragon Vein network to the cleanest point it could find.
"What do you do with it," said Min-Seo.
Han-Ho looked at the visitor.
At the thing still actively working on becoming cleaner even now.
Made a note.
Then crouched down.
Not to clean the visitor.
Just to be at the same level.
"Hello," said Han-Ho.
No response.
Nothing familiar.
He pressed his hand against the pavement right beside it.
Not touching it.
Just adjacent.
The active ambient technique.
Diffuse.
The cleaning field extending from his hand in all directions.
The visitor sat in the cleaning field.
For three seconds nothing happened.
Then the quality of the visitor's energy changed.
Not dramatically.
Not instantly.
But measurably.
The energy it was producing — the clean energy it had been trying to make for its entire existence — became slightly cleaner.
In three seconds.
From proximity to the cleaning field.
It was getting better at what it had always been trying to do.
Because it was near something that did it.
Han-Ho lowered his hand.
Made notes.
Filed them.
Looked at the visitor.
"The very strange world has no concept of cleaning as a technique," said Han-Ho. "But it has been trying to produce clean energy. The proximity to the cleaning field improved its output."
"It learned from you," said Min-Seo. "In three seconds."
"Not learned," said Han-Ho. "Improved. It was already doing the right thing. The cleaning field just showed it a better angle. Same as the technique development in the fantasy world. The angle shift."
Min-Seo looked at the visitor.
At the thing that had been trying to produce clean energy for its entire existence and had just gotten slightly better at it from three seconds next to Han-Ho's hand.
"What do you do with it," said Min-Seo again.
Han-Ho looked at the visitor.
At his bag.
At the bag pocket.
At River at the mesh.
At the sprite between the notebook and the left pen.
At the shard between the notebook and the right pen.
"River," said Han-Ho.
"Yes Master," said River.
"Can you communicate with it."
River was quiet for a moment.
"I can try," said River. "It is made of energy. I am made of energy. The communication method is—" A pause. "Different from how I communicate with the sprite. But yes. I can try."
River emerged from the bag.
Floated to the visitor.
Regarded it.
The visitor regarded River.
Two small energy entities from two very different worlds on a Tuesday morning pavement in Mapo-gu.
River made a sound.
Not words.
Just energy communication.
The visitor responded.
A different sound.
Not translatable in any direct sense.
But the quality of it was readable.
Han-Ho pressed his hand against the adjacent pavement and read the ambient energy quality during the exchange.
Made notes.
"River," said Han-Ho.
"Yes Master."
"What did it say."
River was quiet for a moment.
"It said—" River paused. "The closest translation I have. It said: you are clean. How."
"You told it," said Han-Ho.
"Yes," said River. "I told it: the man cleans things. He has been cleaning things for a very long time. This is the cleanest point on his road."
"And," said Han-Ho.
"It said: I want to watch," said River.
Han-Ho looked at the visitor.
At the coin-sized thing from the very strange world that had followed clean energy through a dimensional network to a storm drain in Mapo-gu and wanted to watch.
He made a note.
He looked at River.
"It can stay for the route," said Han-Ho. "If it stays at a safe distance from the cleaning field during active sessions."
River communicated this.
The visitor's energy quality shifted.
The closest approximation: yes.
"Good," said Han-Ho.
He stood up.
Looked at drain six.
Which still needed its completion note.
He made it.
Filed it.
Looked at the visitor.
"Drain seven is next," said Han-Ho.
He walked to drain seven.
The visitor followed.
At approximately twenty centimeters.
Min-Seo watched this.
At Han-Ho walking to drain seven.
At the coin-sized entity from the very strange world following at twenty centimeters.
At Moru on the left shoulder.
Kjor on the right shoulder.
River floating beside the visitor translating.
The sprite in the bag.
The shard in the bag.
The notebook in the bag.
The eleven — twelve — notes in the vest pocket.
"Han-Ho," said Min-Seo.
"Yes."
"The visitor."
"Yes."
"It is following you."
"Yes," said Han-Ho. "Drain seven."
"At twenty centimeters."
"Yes."
"From the very strange world."
"Yes," said Han-Ho. "The threshold residue at drain seven is a Class B accumulation. The visitor should move back thirty centimeters during the cleaning. River please communicate."
River communicated.
The visitor moved back thirty centimeters.
"Thank you," said Han-Ho.
He cleaned drain seven.
Made a note.
Filed it.
Continued.
The visitor followed at twenty centimeters.
Still actively working.
Still trying to make clean energy.
Getting slightly better at it.
One drain at a time.
The Tuesday route continued.
