The buried structure remained completely still after ejecting the black dodecahedron.
Kael stood inside one of its enormous chambers with the object resting in his hand while dozens of his other occupied positions remained scattered throughout the facility.
Nothing else moved.
The corridors had stopped rearranging, the chambers no longer exchanged positions, and the strange architecture had returned to the same absolute silence it had possessed before Kael inserted the object.
Kael wasn’t convinced it had deactivated.
His Absolute Spatial Sense still perceived every part of the structure within range.
The physical mechanisms responsible for changing the relationships between rooms remained intact, although calling them mechanisms was somewhat misleading.
There were no gears, channels, power sources, or moving assemblies that resembled machinery.
The structure simply possessed physical relationships that could change according to principles Kael had not yet deciphered.
He looked down at the dodecahedron.
Two tiny geometric indentations now marked one of its previously perfect faces.
Occupied.
Uncounted.
That remained the closest translation Kael could produce.
The second concept interested him more.
At first, he had interpreted it as an inability to count the number of positions he occupied, but after comparing the pattern against several records inside the structure, the meaning seemed more specific.
It wasn’t merely too many.
It represented the absence of an assignable finite occupancy value.
Back in Greyhaven, Rhea was still staring at him.
“Master.” “Hmm?” “How many places can you actually be in?” Kael looked toward her.
“A lot.” “No.” “No?” “I’m not accepting that answer anymore.” Kael raised an eyebrow.
Rhea began counting on her fingers.
“Ten thousand?” Kael shrugged.
“A hundred thousand?” Another shrug.
“A million?” “Probably.” Rhea stopped.
“Probably?” “I haven’t counted.” Her expression became increasingly incredulous.
“A billion?” Kael thought about it.
“Maybe.” “How can you not know?” “Because I stopped testing.” “Why?” “It got boring.” Rhea stared at him.
There were moments when being Kael’s disciple gave her access to profound knowledge about combat, movement, and things no ordinary hunter could possibly experience.
Then there were moments like this.
“You stopped counting how many places you can simultaneously exist because you got bored?” “Yes.” Rhea rubbed her forehead.
“Of course you did.” Deep underground, Kael returned his attention to the facility.
If the structure had merely shut down, there wasn’t much reason to remain interested in its current state.
But something about its physical configuration suggested otherwise.
It was waiting.
Not consciously, as far as Kael could determine.
Waiting in the same way a lock waited for a key.
Kael decided to test it.
Most of his occupied positions inside the facility disappeared.
One remained.
Nothing happened.
A second Kael occupied another point approximately twenty meters away.
A nearby corridor shifted.
Kael’s attention sharpened.
He removed the second position.
The corridor returned.
Two positions again.
The corridor moved.
“Ah.” Back in Greyhaven, Rhea heard him.
“What?” “Nothing.” “Whenever you say nothing, something is happening.” Kael ignored her.
Three occupied positions appeared inside the buried structure.
He arranged them in a straight line.
Nothing.
He changed their distances.
A wall moved.
He arranged the three positions into a triangle.
An entire chamber rotated relative to the surrounding structure.
Kael changed one angle.
The chamber returned.
He repeated the original configuration.
It moved again.
That was enough to confirm it.
The structure wasn’t simply measuring how many positions were occupied.
It cared about their relationship.
Distance.
Angle.
Sequence.
Possibly duration.
Kael created four positions and arranged them according to the vertices of a tetrahedron.
Several rooms reorganized simultaneously.
Back in Greyhaven, a faint smile appeared on his face.
Rhea immediately became suspicious.
“What are you doing?” “Talking.” “To who?” “The building.” Rhea stopped stretching.
“You’re talking to the building?” “Seems like it.” “And is the building talking back?” “By moving rooms.” Rhea considered the sentence.
Strangely, after everything that had happened since she met him, it barely qualified as ridiculous anymore.
“So you’re teaching it?” “No.” Kael created another pattern.
A corridor appeared.
“I’m learning how it talks.” That somehow sounded worse.
Rhea decided her mysterious underground competition for Kael’s attention could wait.
She picked up her practice blade.
“Are we training or are you going to spend the entire day having a conversation with architecture?” “Training.” Kael looked toward her stance.
“Your awareness is bad.” Rhea lowered the weapon slightly.
“Good morning to you too.” “You focus too much on whatever you’re attacking.” “Isn’t that generally where I’m supposed to focus?” “No.” “Where should I look?” “Everywhere.” Rhea stared at him.
“Master, I don’t have your ridiculous senses.” “I know.” “Then how exactly am I supposed to look everywhere?” Kael walked toward the equipment along the wall.
“You don’t need to see everything.” He picked up a strip of dark cloth.
“You need to stop depending on seeing one thing.” Rhea looked at the cloth.
Then at him.
“No.” Several minutes later, she stood in the middle of the yard blindfolded.
Kael had rearranged the training area around her.
Wooden pieces hung from ropes.
Small bells had been attached at different heights.
Several swinging targets moved whenever another Kael pulled the connected ropes.
Narrow poles created obstacles across the ground.
Rhea couldn’t see any of them.
“The objective?” she asked.
“Other wall.” “Of course it is.” “Don’t get touched.” “By what?” “Anything.” Rhea sighed and stepped forward.
Her right foot immediately struck a wooden pole.
She stumbled.
Kael’s voice came from somewhere nearby.
“That wasn’t even moving.” “I KNOW.” Rhea recovered and continued.
A faint bell sounded on her left.
She reacted toward it.
A hanging wooden block struck her right shoulder.
“Ow!” “You followed the sound.” “Wasn’t that the point?” “No.” Rhea removed the blindfold.
“Then what is the point?” Kael pointed around the yard.
“Sound tells you something happened.
It doesn’t tell you everything else stopped happening.” Rhea frowned.
Kael continued.
“Remember where things are.
Feel the ground when something moves.
Listen for changes, not just noise.
Use the air.
Use what you saw before losing sight.” Rhea looked around the course.
It began making more sense.
She tied the blindfold again.
The next attempt lasted longer.
Not much longer.
But longer.
After the seventh failure, Rhea ripped the cloth off again.
“This is easy for you.” “Yes.” “Because you can see everything without using your eyes.” “Yes.” “Then demonstrate without that.” Kael thought about it.
Absolute Spatial Sense wasn’t something he simply turned off.
It was a passive aspect of his existence.
Even if he closed his eyes, covered his ears, and buried himself beneath a mountain, space within his range remained completely perceptible.
But Rhea wasn’t asking him to stop perceiving.
She wanted him to demonstrate using the information available to her.
“Fine.” Kael blindfolded himself.
His Spatial Sense still mapped every object perfectly.
He simply refused to use that information when deciding how to move.
Instead, he listened.
A rope creaked.
His foot shifted.
A wooden block passed beside him.
A bell moved behind his shoulder.
He felt the faint change in air and stepped beneath it.
The ground vibrated when one of the suspended weights landed.
Kael changed direction.
He crossed the entire yard without being touched.
Rhea stared at him.
“That doesn’t count.” “You told me not to use Spatial Sense.” “You still did it perfectly.” “I’ve practiced.” Rhea narrowed her eyes.
“For how long?” Kael removed the blindfold.
“We’ve discussed this.” “No, I’ve guessed and you’ve refused to answer.” “Training.” Rhea ignored him.
“Twenty years?” Kael said nothing.
“Thirty?” Nothing.
“Fifty?” Kael walked toward the training equipment.
Rhea followed.
“Seventy?” Nothing.
She laughed.
“What, a hundred?” Kael paused.
It lasted less than half a second.
Then he continued walking.
Rhea’s smile disappeared.
Her eyes narrowed.
“Master.” “Training.” Rhea slowly followed him.
For once, she didn’t continue guessing.
Deep beneath the Hollow Depth, Kael created another occupancy arrangement.
The structure responded immediately.
A section that had previously remained sealed rearranged itself.
An enormous chamber appeared.
Hundreds of Kael’s occupied positions simultaneously perceived its contents.
Thousands of tiny geometric structures filled the room.
At first, Kael assumed he was looking at a model of the facility.
Then he examined the relationships.
The scale was wrong.
This wasn’t architecture.
It was a map.
But not a geographical map in any conventional sense.
There were no mountains.
No rivers.
No borders.
The markers represented locations according to occupancy.
Some regions contained dense clusters.
Others had almost none.
One enormous region was represented differently from everything surrounding it.
No occupancy.
Kael studied the pattern.
It wasn’t merely empty.
The distinction mattered.
An empty room could still possess a location capable of being occupied.
This represented something closer to occupancy being absent as a property.
Again, the resemblance caught his attention.
Nihyrium.
Not identical.
Not even close enough for Kael to assume a direct connection.
But whoever had created these records possessed concepts that humanity certainly didn’t appear to use.
Kael examined the map further.
One marker matched the buried structure where he currently stood.
Then he noticed others.
Far away.
Many others.
Some appeared inactive.
Some were incomplete.
Several were too distant for him to determine their exact geographical locations using the information currently available.
One direction, however, was familiar.
Kael remembered Marcus’s map.
The Silent Expanse.
Back in Greyhaven, Rhea had just tied the blindfold around her head again when Kael spoke.
“Where was the Silent Expanse?” She froze.
Slowly, she removed the blindfold.
“No.” Kael looked at her.
“I asked where it was.” “And I’m answering emotionally.” Kael walked inside the house and retrieved Marcus’s map.
Rhea followed with growing dread.
He spread it across the table.
His finger moved.
North.
Then farther.
It stopped over the enormous blank territory.
The relative direction matched.
There was another structure beneath the Silent Expanse.
Its marker was different.
Kael compared the spatial patterns.
The Hollow Depth facility appeared to carry a meaning close to dormant.
The Silent Expanse marker represented something else.
Occupied.
Continuously.
Kael’s interest increased.
Rhea saw it happen.
“No.” “I haven’t said anything.” “You don’t need to.” “I’m not going there.” Rhea paused.
“You’re not?” “Not now.” That surprised her.
Kael looked toward the training yard.
“You still can’t cross the yard blindfolded.” Rhea wasn’t sure whether to feel touched or insulted.
Kael had no intention of abandoning something he had chosen to do simply because another curiosity appeared.
He wanted to train Rhea.
So he would.
The Silent Expanse wasn’t going anywhere.
At least, probably not.
Far beyond Greyhaven, however, something else changed.
Deep beneath another region of the world, a structure similar to the one inside the Hollow Depth had remained silent for longer than any surviving human record.
One room moved.
A hand touched a geometric wall.
The hand wasn’t entirely human.
A voice broke the silence.
“An occupancy answer?” Another voice responded from somewhere deeper.
“No.” A pause followed.
“An occupancy error.” Back inside the Hollow Depth facility, Kael continued experimenting.
He had learned enough of the spatial language to attempt something more complicated.
Dozens of occupied positions appeared.
They arranged themselves across multiple chambers.
Distances changed.
Angles aligned.
Several positions disappeared while others appeared according to a carefully timed sequence.
The structure moved.
Kael adjusted the pattern.
Again.
Wrong.
He changed it.
Again.
Closer.
Eventually, the meaning became crude but understandable.
WHO OCCUPIES THERE?
Kael directed the relationship toward the marker corresponding to the Silent Expanse.
Nothing happened.
Five seconds passed.
Ten.
Then the facility rearranged.
Several geometric markers shifted.
Kael read the first response.
UNKNOWN.
Another pattern formed.
STILL OCCUPIED.
Then another.
Kael became completely still.
The final meaning was harder to translate, but after comparing it against several records, he understood enough.
SINCE BEFORE RECORD.
Back in Greyhaven, Rhea was halfway through another blind attempt when she heard Kael make a quiet sound of amusement.
She immediately stopped.
“What did the building say?” Kael looked toward Marcus’s map.
“Something’s there.” Rhea pulled off the blindfold.
“Of course something’s there.” Kael’s other positions continued examining the distant marker.
Whatever occupied the Silent Expanse had apparently been there before the buried structure’s available records began.
How long that meant, Kael had no idea.
Centuries?
Thousands of years?
Longer?
For most people, that uncertainty would have been a warning.
For Kael, it was an invitation to curiosity.
He looked at the blank region on Marcus’s map once more before folding it.
He wasn’t going there today.
He had already decided what he was doing today.
Kael looked toward Rhea.
“Again.” Rhea stared at him.
“You just discovered some unknown thing that’s apparently been sitting in the Silent Expanse since before recorded history.” “Yes.” “And we’re going back to training?” “Yes.” Rhea slowly put the blindfold back on.
She wasn’t sure whether her master had his priorities completely wrong or completely right.
With Kael, she suspected there wasn’t much difference.
