NGĀ HAERENGA

Vardheim was not Te Waka Tōhorā with snow.

That became obvious in the first five minutes.

The sanctuary sat inside and around a deep fjord valley. Dark stone buildings climbed the slopes. Timber bridges crossed narrow gaps. Warm water ran through channels beneath paths to keep ice from taking over.

Runes marked doors, tools, maps and warning signs.

Not random mysterious symbols.

Writing.

Information.

History.

Erik's aunt Solveig met us at the gate. His mother reached him first.

She hugged him so hard his boots left the ground.

Nobody laughed.

Then she turned on Grog.

“You let him fly that wreck?”

Grog pointed at Erik. “I met him after the wreck.”

“Still.”

Grog looked impressed.

I understood immediately where Erik got some of his personality.

We were taken to a long hall warmed by pipes beneath the floor. Half the pipes were cold.

Solveig spread local maps across a table.

She did not ask me to fix anything.

Good.

She asked what Te Waka Tōhorā had experienced.

I explained the Deep Current, Dave's extraction network and the lattice we built.

Then she explained Vardheim.

Their sanctuary moved warmth through stone and water. Hot springs fed part of the system. Mīharo pathways moved the rest. Rune-marked gates recorded pressure, direction and access.

“Our system was designed for deep winter,” Solveig said. “It should be strongest now.”

“But it's not,” Piripi said.

“No.”

A young engineer named Freja placed three measurements beside the map.

The drop began at the same time Rangi Energy expanded on Earth.

Hemi looked at me.

“Same problem.”

“Partly,” Freja said.

Hemi frowned.

She tapped a second line.

“Our western heat route was damaged years ago. We closed it instead of rebuilding. The remaining system carried the extra load until something outside began pulling.”

Two pressures again.

External extraction.

Internal weakness.

Before we left the hall, Freja made us sign a visitor agreement. Hemi rolled his eyes until he read it. The rules protected local knowledge from being copied out of context, required us to ask before touching active systems and made clear that Vardheim could end our involvement whenever it chose.

“You have more rules than Te Waka Tōhorā,” he complained.

Freja replied, “You arrived because our systems are failing. That does not mean our boundaries failed too.”

Hemi had no answer. I quietly loved her for it.

Aroha the World-Shaper was not the answer.

Vardheim already had people who understood Vardheim.

What they needed was another set of eyes and enough time.

Numbers became real when we visited the lower homes.

Three families had moved into one hall because their own heating channels failed.

Children slept in layers of blankets.

Food stores were being shifted toward the warmest chambers.

Nobody was freezing to death yet.

Yet mattered.

Erik knew everybody.

He stopped every few metres.

An old man hugged him.

Two little kids punched his arms and accused him of dying without permission.

His mother kept one hand on his shoulder as if she expected the Between to steal him again.

Hemi became very quiet.

At one house, a girl about eight showed us a frozen line running through her bedroom wall.

“It used to glow,” she said.

Hemi touched the stone.

Orange warmth spread through his fingers.

The line flickered.

Grog stopped him.

“Temporary heat only.”

“She's cold.”

“Then warm the room. Do not connect yourself to a failing system you do not understand.”

Hemi's jaw tightened.

But he listened.

He warmed a metal plate instead. The room temperature rose slowly.

The girl's mother thanked him.

Outside, Hemi kicked snow off a step.

“We could send heat from Te Waka Tōhorā.”

Piripi said, “Across a route we only just reopened?”

“For people who need it.”

“And if our system starts draining too?”

Hemi turned on him.

“Then at least we tried.”

I understood the feeling.

When suffering was in front of you, caution could look cruel.

But I had nearly killed myself in Book Three by trying to fix every weak line at once.

“We help them build something that keeps working after we leave,” I said.

Hemi laughed bitterly.

“You sound like Grog.”

“That's becoming a serious problem.”

He smiled despite himself.

Then he looked back through the window at the little girl.

“Just don't make them wait forever.”

One family refused extra help because another household was colder. Solveig accepted the decision but sent a healer to check them anyway. The choice reminded me that communities were not simply helpless victims waiting for us. They were already rationing, repairing, sharing and making hard decisions long before we arrived.

Our presence added options. It did not create courage where none had existed.

I promised I wouldn't.

I did not promise I could save them.

That difference mattered.

Erik's mother was called Ingrid.

She did not approve of his rescue mission.

This was clear because she told him every fifteen minutes.

“You stole a flight craft.”

“Borrowed.”

“You crashed it into another sanctuary.”

“Eventually.”

“You could have died.”

Erik looked at his soup.

“People here could have died too.”

That ended the argument.

Ingrid sat down.

Her anger folded into fear.

“You are twelve.”

“I know.”

I knew that sentence.

Mum had said versions of it to me for years.

Ingrid noticed me listening.

“And you?”

“Eleven.”

She closed her eyes.

“Excellent. Children saving sanctuaries.”

Grog, at the other end of the table, said, “We try to discourage it.”

“Not very well.”

I liked her.

Later Ingrid told us what happened before Erik left.

Vardheim's council had rationed heat and begun planning an evacuation of the coldest quarter.

Erik argued they should contact other sanctuaries.

The council said the old routes were unsafe.

Erik asked how unsafe compared with winter.

Nobody gave him an answer he accepted.

So he found an old craft, followed damaged route markers and left.

Hemi looked delighted.

“See?”

Erik snapped, “It was stupid.”

Hemi blinked.

Erik rubbed his burned hand.

“Necessary can still be stupid.”

That sentence stayed with me.

Sometimes people survived because somebody took a terrible risk.

That did not magically turn the risk into good planning.

Erik had reached us.

He had also nearly died and almost carried an unstable route straight into Te Waka Tōhorā.

Both were true.

Ingrid put her arm around him.

“Next time you save us, ask first.”

Erik smiled.

Ingrid later apologised to me for snapping at Grog. “Fear makes me rude,” she said.

“Fear makes Grog annoying.”

From across the room Grog said, “I can hear you.”

Ingrid smiled for the first time.

Watching them made me think about parents differently. Mum's fear had once felt like a wall around me. Now I could see the love inside it without agreeing with every choice fear produced. Children grow by learning adults are people too. Adults probably hate that.

“No promises.”

She smacked the back of his head gently.

Some family languages were universal.

Vardheim's western gate had not opened in fourteen years.

It was carved into a stone wall above a geothermal channel.

Rows of runes marked its edges.

Freja made one thing clear before we began.

“Do not call this a spell.”

Hemi raised both hands.

“I wasn't going to.”

“You absolutely were.”

She was right.

The runes labelled functions.

Open.

Close.

Heat.

Pressure.

Emergency release.

Names of builders.

Dates.

The Mīharo lived in the relationships between stone, water, people and sanctuary pathways. The writing helped people understand and guide those relationships.

I liked that distinction.

Freja showed us where the gate failed.

One stone section had shifted years ago. Instead of rebuilding it, Vardheim rerouted pressure through the eastern system.

It worked.

Until Dave's extraction made the whole network weaker.

“Can you shape the stone back?” Hemi asked me.

“Probably.”

Freja said, “No.”

We both looked at her.

“That stone has been under stress for fourteen years. If Aroha pushes it back without relieving pressure, it may split the wall.”

Reweti would have loved her.

We spent two days measuring.

Piripi mapped water.

Hemi tested heat.

Erik translated old maintenance notes.

Moemoeā found a warning everyone else had missed because it had been carved behind a later support.

I sensed where the living current still touched the gate.

At last we had a plan.

Freja would release pressure.

Local builders would shift the stone.

I would help the Mīharo path recognise the repaired route.

Not fix Vardheim.

One task.

One system.

Local people leading it.

Freja also made us document every change before we touched the gate. Old measurements, new measurements, expected effects, safe stopping points. Hemi called it boring until she showed him a record from fourteen years earlier proving exactly why the gate had been abandoned.

Someone had skipped one pressure check because the repair was urgent.

The resulting crack took months to stabilise.

Boring paperwork, apparently, could be the memory of previous mistakes.

When the gate finally opened three centimetres, warm air rushed through.

Everybody cheered as if we had moved a mountain.

Maybe three centimetres was enough.

The repaired gate should have strengthened Vardheim.

Instead it revealed another problem.

The moment warm Mīharo began flowing through the western route, something pulled back.

White light.

My throat tightened.

Dave.

I had not felt his network this strongly since leaving Te Waka Tōhorā.

Freja's instruments jumped.

Heat fell.

Hemi swore.

Erik shouted instructions.

We closed the gate before the pull could lock on.

Silence filled the chamber.

Then Hemi said, “He's taking from here too.”

Not intentionally from Vardheim, perhaps.

That was worse in a different way.

Dave had built a network that recognised Mīharo wherever connected Earth pathways came within reach.

He did not need to know each sanctuary existed.

His system treated all of it as energy.

Freja stared at the readings.

“One man's machine reaches a place he has never heard of.”

I thought of all the old sanctuary marks in the network map.

How many were weakening without understanding why?

Grog sent an urgent message back to Te Waka Tōhorā.

Hemi paced.

“This proves it.”

“Proves what?” I asked.

“We can't keep hiding separately. One person on Earth can hurt all of us because nobody talks to anybody.”

He was partly right.

Again.

That was becoming the most dangerous thing about Hemi's ideas.

They started from truths.

Moemoeā watched him carefully.

“Talking is not the same as opening everything.”

“Not yet.”

The words were quiet.

I looked at him.

Hemi looked back.

Something had shifted.

He no longer saw open routes only as help.

We sent the readings to three other sanctuaries. Two reported similar drops. The third did not.

That difference mattered. Dave's network was not affecting every place equally. Local design, distance, Earth connections and old repairs changed vulnerability.

Hemi wanted one explanation because one explanation made one solution easier. The evidence kept refusing to cooperate. I began to appreciate evidence for exactly that reason: it could be inconvenient enough to save you from your favourite idea.

He was beginning to see them as justice.

That was bigger.

And harder to argue with.

The answer came from combining Vardheim's gates with Te Waka Tōhorā's lattice.

Not merging them.

Learning from both.

Freja's system had strong local controls. Every gate had clear permission states.

Our lattice was better at rerouting pressure.

Erik called the idea ugly.

“Good,” I said. “Ugly systems still work.”

We designed a temporary buffer between the sanctuary route and Earth's extraction pull.

The important part was that neither sanctuary could activate it alone.

Two gates.

Two permissions.

Two stop controls.

Hemi hated that.

“What if one side needs help and the other says no?”

Erik answered before I did.

“Then you talk.”

“While people freeze?”

“Better than somebody deciding my home belongs to them because they have a good reason.”

Hemi looked away.

Moemoeā squeezed his hand.

He let her.

Erik and I spent hours testing the buffer on a small channel.

He was good at noticing patterns I missed.

I was better at feeling when the living current changed before the instruments showed it.

We argued constantly.

Not like Hemi and me.

Different.

Erik would say, “Your feeling is not data.”

I would say, “Your data is three seconds late.”

Then we would both be right and annoying.

At midnight, after our fourth failed test, he handed me a mug of something hot.

“What is it?”

“Drink.”

“That is suspicious.”

“You ate a glowing fruit from a moving market stall without asking.”

Fair.

It was hot chocolate.

Much better than Hemi's Dutch version.

I told him that.

He asked why I knew a Dutch version.

I explained Hemi.

Erik shook his head.

“Your life is strange.”

The first successful buffer test lasted only twenty seconds. At second fourteen, Vardheim withdrew permission on purpose. The path closed cleanly. At second seventeen, Te Waka Tōhorā reopened its side, but nothing happened until Vardheim agreed again.

Erik looked pleased.

“That,” he said, “is what trust looks like in engineering.”

I wrote the sentence in my notebook. Trust was not a permanently open door. Sometimes trust was knowing a door would close when you asked and still be there when you chose to open it again.

“You crashed out of another world.”

“Also fair.”

We went back to work.

Hemi opened a small route without permission.

Not to Vardheim.

To Earth.

He said he only wanted to test whether free Mīharo could flow around Dave's extraction.

He chose an abandoned forest path far from people.

He kept the opening tiny.

He told himself all the reasons it was safe.

Then the fire started.

Not a normal fire.

His Mīharo crossed the open path and found dry grass on Earth.

Heat answered heat.

A line of flame raced through the clearing.

Hemi closed the route immediately.

Grog and local kaitiaki contained the fire before it spread.

Nobody was hurt.

That did not make it okay.

I found Hemi sitting outside the gate chamber with ash on his hands.

He looked younger than twelve.

“I thought I could control it.”

I sat beside him.

“I know.”

“I was trying to prove there was another way.”

“I know.”

“Stop saying that.”

“Why?”

“Because it sounds worse.”

He was right.

Understanding his reason did not remove the consequence.

Moemoeā arrived.

Hemi could barely look at her.

She sat on his other side.

“You promised you'd listen.”

“I know.”

“You didn't.”

“I know.”

Her eyes filled with tears.

“I can't make your choices for you.”

Hemi whispered, “I know.”

This time the words sounded different.

Grog suspended him from gate work.

Hemi did not argue.

The Earth clearing where Hemi's test went wrong belonged to nobody in Open Roads. That became one of the hardest facts for him to face. He had chosen an “empty” place because no houses were nearby, but empty had meant empty of people he knew about. It still held plants, animals, fire risk and connections to others downstream.

A place did not become available for experimentation simply because nobody was standing in front of you to object.

That frightened me more than if he had.

He understood exactly what he had done.

And part of him still believed the idea itself was right.

The buffer worked on the sixth attempt.

We reopened the western gate.

Dave's network pulled.

The buffer redirected pressure through three local routes, then closed the Earth-facing layer before extraction could lock on.

Warmth moved into Vardheim.

Not from Te Waka Tōhorā.

From Vardheim's own restored system.

That mattered.

We were not powering their sanctuary.

We helped them recover what already belonged there.

The lower halls warmed first.

Ice melted from one blocked channel.

A food room reopened.

The eight-year-old girl whose bedroom line had frozen ran outside without a coat and had to be dragged back by her mother.

Erik stood beside me watching lights return along the valley.

“I thought I would not see this again.”

“You should have trusted adults and waited calmly.”

He looked at me.

I smiled.

He laughed.

“You are terrible.”

“I've been told.”

Ingrid found us and pulled both of us into a hug without warning.

Erik complained.

I did not.

Vardheim was not completely fixed.

The network still needed rebuilding.

Dave still existed.

Other sanctuaries might still be weakening.

But winter was no longer an immediate threat.

The council thanked us publicly.

I made Freja stand beside me because I refused to let anybody tell the story as Aroha-the-World-Shaper saved Vardheim.

Freja had designed half the solution.

Local builders had done the dangerous work.

Erik had found us.

We had helped.

That was enough.

Hemi stood at the back beside Moemoeā.

He clapped too.

Vardheim held a meal after the lower halls warmed. It was not a victory feast so much as everyone finally having enough energy to cook together. People brought what they had. Some dishes were familiar to Erik and completely strange to us.

Nobody asked us to perform Te Waka Tōhorā culture for them, and we did not treat Vardheim like a museum. We were guests in a living community.

That ordinary respect felt like a better model for sanctuary connection than any grand speech about unity.

But he did not look happy.

The solution had proven cooperation could work.

To Hemi, it had also proven how much help had been delayed by closed doors.

Erik returned to Te Waka Tōhorā with us.

His mother hated the idea.

His mother also helped pack his bag.

Vardheim wanted a permanent young liaison while the sanctuary network was investigated.

Erik volunteered before anyone else could.

“You like crashing into places?” I asked.

“I am improving.”

His repaired craft stayed behind.

We used the gate.

Much safer.

Before leaving, Solveig gave Te Waka Tōhorā a copy of Vardheim's old route records.

Not ownership.

A shared copy.

Te Waka Tōhorā gave them sections of our pressure-lattice design under the same terms.

Knowledge exchanged because both sides agreed.

Hemi watched the handover.

“Imagine if every sanctuary did this.”

“Maybe they should,” I said.

His eyes lit.

“Exactly.”

I added, “If they choose to.”

His expression changed.

There it was again.

The line between us.

Back at Te Waka Tōhorā, Erik was given a room near the guest quarter.

Moemoeā immediately declared the Outsiders Club international.

Piripi objected that we still had only two actual outsiders.

Hemi said percentages were irrelevant.

Kiki ate the new membership list.

Some traditions deserved preserving.

That night, Erik and I sat on the ridge above the harbour.

He showed me a small carved token from Vardheim.

One rune marked his family name.

Another marked the route home.

“Not magic?” I asked.

“Not by itself.”

He handed it to me.

“It means I know where I belong.”

I gave it back.

“Keep it, then.”

He closed his fingers around it.

Far below, Hemi and Moemoeā walked between market lights holding hands.

Everything looked peaceful.

It was not.

Erik's decision to become a liaison also meant accepting responsibility to both places. He could not simply tell Te Waka Tōhorā whatever Vardheim wanted, or return home and represent us as if he spoke for everyone.

“So you're basically guaranteed to annoy somebody,” I said.

“Probably everyone.”

“Perfect qualification.”

He smiled.

Belonging to more than one place did not make him divided. It gave him more relationships to care for. I understood that deeply.

Dave's network was still growing.

More sanctuary marks were appearing on our maps.

And somewhere inside Hemi, a door had opened that none of us knew how to close.
