NGĀ HAERENGA

I turned eleven standing beside a crater.

This was not Mum's idea of a birthday activity.

The object that had fallen from the sky the night before lay half-buried in broken fern and black soil. Smoke curled from one side. Strange angular marks covered its dark hull.

Grog had ordered everyone away until morning. Hemi had ignored him for six minutes before Moemoeā physically dragged him back.

Now a proper rescue team surrounded the wreck.

Reweti studied the cracked outer shell. Piripi watched the water channels in case anything leaked. I stood where Grog told me to stand and tried not to be annoyed about it.

“Eleven,” Hemi said beside me. “Practically ancient.”

He was twelve now and had become even more confident in opinions nobody had requested.

Moemoeā handed me a wrapped parcel. “Happy birthday. Open it later.”

“Is it food?” Hemi asked.

“Not for you.”

That meant yes.

A metallic knock came from inside the wreck.

Everyone stopped.

Another knock.

Three fast. Two slow.

Grog raised one hand.

“Nobody touches the hull.”

Hemi whispered, “That usually means somebody is about to touch the hull.”

He was right.

Reweti pressed a tool into a split seam. Piripi redirected cool water across the hot metal. The outer panel groaned and opened.

A boy fell out.

He hit the ground, rolled and came up holding a short metal bar like a weapon.

He looked about twelve.

Pale from exhaustion. Dark blond hair. A cut across one cheek. Heavy clothes that made no sense in our warm forest.

He shouted something none of us understood.

Grog kept both hands visible.

The boy shouted again.

Then he looked at me.

Not because I was special.

Because Kiki had flown out from behind my shoulder and landed on my head.

His expression changed from fear to complete confusion.

“Bug?” he said in English.

I laughed.

“Cicada.”

His eyes widened at the sound of my voice.

“You speak English?” Grog asked.

The boy nodded once.

Then he pointed back at the sky.

“Help,” he said. “Please.”

That one word changed the whole morning.

After the rescue team carried Erik away, I stayed beside the wreck with Reweti. Up close, the craft looked less like a mysterious weapon and more like something repaired too many times. Different metals covered old cracks. One panel had been tied into place with woven cord before somebody later bolted over it. Erik had not arrived in a perfect piece of foreign technology. He had arrived in the best thing his people still had that could fly.

That detail made his single word—help—feel heavier.

The wreck was not an attack.

It was a message.

And the person carrying it had nearly died trying to reach us.

His name was Erik.

Not Eirik. He corrected Hemi three times.

Hemi said the extra vowel made it look more interesting.

Erik said he did not care.

I liked him immediately for that.

He spent his first two days in the healing rooms. The crash had bruised his ribs and burned one hand, but nothing was broken.

The harder problem was trust.

Nobody knew how he had found Te Waka Tōhorā.

Erik said he came from a sanctuary called Vardheim, far to the north through routes none of us used.

Grog had heard the name.

Reweti had too.

That made everyone more worried, not less.

“The old sanctuary network closed most direct routes generations ago,” Grog explained.

“Why?” I asked.

“Different reasons. Safety. Conflict. Distance. Some communities chose privacy.”

Hemi leaned against the wall.

“More hiding.”

Grog ignored him.

Erik sat upright despite the healer telling him not to.

“Vardheim is failing.”

His English was good but careful, as if he translated each sentence inside his head before speaking.

“What does failing mean?” Moemoeā asked.

“Cold system. Light system. Food rooms. Paths. Everything.”

He drew a shape on the table with one finger.

A branching pattern.

“Our sanctuary was built inside a mountain-fjord system. Stone, water, ice, timber. The old routes carry power between them.”

I thought of our Deep Current.

“Same kind of problem?”

“Maybe.”

He looked at the hei tiki at my chest and then away quickly.

“We heard of a place that repaired living paths. Whale place.”

Hemi smiled. “Whale place is good.”

Erik did not smile.

“People are cold. We do not have enough heat to last winter.”

That ended the jokes.

Grog asked how many people.

Erik gave a number large enough to make my stomach drop.

He had not crossed worlds for adventure.

He had crossed because his home was running out of time.

When the healers finally made him lie down, I stayed by the doorway.

He noticed.

“You do not trust me?” he asked.

I thought about Dave.

Hemi.

Prophecies.

Strangers.

“I don't know you.”

Erik nodded.

“Better answer.”

I smiled.

The healers also found a small carved token strapped beneath Erik's shirt. He refused to let anyone take it until Grog promised it would stay in sight. Later Erik explained it carried his family mark and a route symbol for home. He had brought almost nothing else.

I recognised the way he held it. I touched Ru's hei tiki without thinking. Two different objects, two different cultures, both carrying the same human fear: if everything else disappears, let me keep one thing that tells me where I come from.

“But I believe you're scared.”

He looked away.

“That is enough for today.”

Three days later Erik caught Hemi copying the symbols from his craft.

“Stop.”

Hemi looked up from his notebook.

“Why?”

“Because you are drawing them wrong.”

“Then teach me.”

Erik stared at him.

Hemi stared back.

Moemoeā whispered, “This could take hours.”

It did.

Erik explained that the marks on his craft were runes.

“Letters first,” he said. “People on Earth make them into all kinds of mysterious things. Mostly they were writing.”

Hemi looked disappointed.

“So no magic alphabet?”

“No.”

Erik paused.

“But Vardheim uses rune forms in our path systems because our builders used what they knew. The symbol is not magic by itself.”

That made sense to me.

Our woven maps were not magical because a pattern automatically contained power. They held knowledge. People used them inside living systems.

Erik drew three runes correctly and wrote ordinary sounds beside them.

Piripi practised carefully.

Moemoeā copied only after asking.

Hemi filled half a page.

I asked Erik whether he minded us learning.

He seemed surprised by the question.

“No. I mind people pretending to know.”

Fair.

In return I showed him some NZSL.

He learned THANK YOU first.

Then HELP.

Then HEMI IS ANNOYING after Moemoeā insisted.

Hemi demanded equal teaching rights.

By lunch, Erik could sign enough to insult him.

The tension around him eased.

Not completely.

Some adults still watched him as though an entire foreign sanctuary might be hiding inside his pockets.

That afternoon I found him staring at Te Rākau Kura.

“Your tree is alive,” he said.

“Very.”

“Our old central hall has a tree too. Not like this. Its roots grow through stone.”

He looked homesick.

“What's it called?”

He told me a name I could not pronounce.

I tried.

He winced.

I tried again.

Worse.

Erik showed us how easy it was to turn unfamiliar writing into fantasy. He pointed to one mark Hemi had copied and asked what we thought it meant. Hemi guessed fire. Piripi guessed protection. Moemoeā guessed journey. Erik said it was simply part of a name.

“People like mystery more than accuracy,” he said.

That sounded familiar. Te ao Māori had been turned into decoration by people who wanted the look without the relationships underneath it. I wrote the lesson down: learn before borrowing; ask before using; do not turn somebody else's culture into a prop for your own adventure.

He laughed for the first time.

It was a small sound.

But something about it made him seem less like the boy from the wreck and more like just Erik.

Te Waka Tōhorā had a council.

I had successfully avoided most council meetings for three years.

This one found me anyway.

Erik stood in the centre of the room while adults discussed his sanctuary as if he were not there.

Some wanted to send supplies through a temporary path.

Some wanted no route opened at all.

One elder said, “We do not know what followed him.”

Another said, “We do know what happens when desperate people open old connections without planning.”

Hemi muttered, “People get helped?”

Moemoeā elbowed him.

Grog asked Erik whether Vardheim could guarantee a controlled receiving gate.

Erik's jaw tightened.

“If we could guarantee our gates, I would not be here.”

Silence.

That was the problem.

Helping Vardheim meant entering an unstable sanctuary through a damaged route.

Not helping meant leaving people to face a failing winter system.

The council decided no.

Not forever.

For now.

They would gather more information.

Erik stood completely still.

I recognised the look.

It was the look I had worn when adults said not now after Koro died.

A phrase that sounded reasonable until you were the person waiting.

Outside, Erik walked fast enough that I had to run after him.

“They're trying to keep people safe,” I said.

He stopped.

“Which people?”

The question landed hard.

He pointed toward the council chamber.

“Your people are safe while they collect information. Mine are cold while you decide.”

I did not have a good answer.

Hemi arrived behind us.

“Exactly.”

I turned.

“Don't.”

“Why? He's right.”

“Being right about the problem doesn't mean every solution is right.”

Hemi's eyes flashed.

“Your favourite sentence.”

Erik looked between us.

“You fight a lot.”

Moemoeā caught up.

“This is normal.”

Piripi nodded.

“Very normal.”

Erik rubbed his face.

“I did not cross the Between to wait.”

I understood.

That night the council decision stayed with me because nobody in the room had been obviously cruel. The people saying no had real reasons. They remembered exposed sanctuaries, broken routes and the way one bad connection had let Aurora's early systems reach us. Erik's need was also real.

I was learning that moral problems were hardest when nobody had invented the stakes. Safety and urgency could both be true. A good answer had to carry more than one truth without pretending one of them disappeared.

But I also remembered how one old relay had let Dave into the Deep Current.

Opening a path because the need was urgent could still put another home at risk.

Balance was becoming less like a philosophy and more like a problem that made everyone angry.

Hemi found an old Vardheim route before the adults did.

Of course he did.

He spent two nights in the archive with Piripi, who claimed he was only there to make sure Hemi did not break anything.

Moemoeā said that was exactly what an accomplice would say.

The route appeared in a damaged woven record beneath another sanctuary name.

Most of it had been deliberately closed.

One thread remained.

“Enough to reopen,” Hemi said.

“Enough to investigate,” I corrected.

He looked at me.

“People are freezing.”

“I know.”

“Do you?”

That annoyed me.

“Yes, Hemi. Caring about risk does not mean I don't care about Erik's people.”

Hemi pushed the map toward me.

“Then open it.”

“I can't just open someone else's sanctuary.”

“You can.”

That was true.

World-Shaping had become strong enough that I could probably help wake an old route.

“That's not the same as having the right.”

Hemi laughed once.

“Who gave the council the right to keep it shut?”

We stared at each other.

Moemoeā stepped between us before the argument became something worse.

“Erik should be here.”

That stopped us.

She was right.

We had turned his home into our debate.

Erik arrived ten minutes later.

He studied the old map.

His fingers shook.

“This was one of ours.”

“Can your people receive it?” I asked.

He swallowed.

“Maybe.”

Hemi said, “Maybe is enough.”

Erik snapped, “Not for you to decide.”

Hemi recoiled.

Erik pointed at the map.

“My people will be standing at the other side if this goes wrong. Not yours.”

Hemi's anger drained.

That was the first time I saw his belief meet the person it was supposed to help.

He looked away.

“Fine.”

Erik took a breath.

“I want the route investigated. I want help. I do not want someone opening my home like a door because they think freedom sounds good.”

I looked at Hemi.

Later Hemi admitted Erik's response had shaken him. “I thought I was arguing for him,” he said. “Then he looked at me like I was another person deciding his life.”

I did not tell him that was exactly what had happened. He already knew.

For the rest of the evening he helped Erik translate the old route notes instead of demanding the gate be opened. That did not solve Hemi's larger belief, but it proved he could still change his behaviour when a real person complicated the idea in his head.

He nodded.

Not happily.

But he nodded.

Hemi disappeared after the archive argument.

Moemoeā found him near the fire gardens.

I did not follow immediately.

Some conversations belonged to the people inside them.

Later Moemoeā told me enough.

Hemi had not been angry at Erik.

He had been angry at himself.

“I sounded like them,” he said.

“Like who?”

“Everyone who decided what was best for me without asking.”

That scared him more than being wrong about a map.

Moemoeā sat beside him until the fire channels dimmed.

“You're not them because you made one bad choice,” she said.

“What if I keep making it?”

“Then I'll tell you.”

Hemi laughed weakly.

“You already do.”

“Exactly.”

He looked at her.

“And if I don't listen?”

Moemoeā was quiet for a long time.

Then she said, “I'll still care about you. That doesn't mean I'll help you do something wrong.”

That was the promise.

Not I'll never leave.

Not I'll always agree.

I love you so much I will become whatever you need.

Something stronger.

I will care, and I will still tell the truth.

A few days later I found them holding hands under the Outsiders Club root.

Hemi dropped hers immediately.

Moemoeā grabbed it again.

“Coward,” she told him.

His ears turned red.

Piripi walked into a branch because he was trying not to stare.

Erik looked confused.

I explained quietly.

“They're becoming a thing.”

“A thing?”

“Very technical term.”

Erik nodded seriously.

“We have this in Vardheim too.”

I laughed.

Hemi threw a cushion at us.

The next day Moemoeā told me she had meant every word. “People think staying means never leaving somebody's side,” she said. “Sometimes staying means refusing to disappear just because the conversation got ugly.”

I thought of Mum and Dad. Their marriage had ended, but neither had stopped being our parent. Staying had taken a different shape.

Moemoeā's version of love was starting to sound like that: connection without surrender. I hoped Hemi understood what a gift that was.

For an afternoon, nobody talked about failing sanctuaries or Dave.

We were eleven and twelve.

That mattered too.

The investigation team found something bigger than a route to Vardheim.

They found a network.

Old sanctuary maps had been stored separately for generations, partly for safety. When we overlaid them, fragments connected.

Te Waka Tōhorā.

Vardheim.

The Earth Sanctuary.

Other names I had never seen.

Some routes were active.

Some deliberately sealed.

Some ended in blank space.

Grog warned us not to romanticise it.

“This was never one magical world with one government.”

Good.

I did not want that.

Different communities had built different ways to survive.

Some worked together.

Some disagreed.

Some disappeared.

A few old records described meetings where sanctuary representatives argued for days over whether routes should stay open.

Hemi read those with intense interest.

“So people have always wanted this.”

“Some people,” Whaea Anahera corrected.

“And some wanted everything shut.”

“Yes.”

Hemi smiled as if history had proven him right.

I read the rest.

One sanctuary had been exposed through an open route and abandoned.

Another had become isolated so long that a preventable illness spread before help arrived.

History did not prove one side right.

It proved choices had costs.

Erik found Vardheim's mark in the network.

Beside it was an old instruction.

REOPEN ONLY WITH BOTH GATES HELD.

“Both gates,” I said.

Erik nodded.

“Your side and ours.”

That changed the council's decision.

If Vardheim could hold its gate long enough, we could open a controlled crossing instead of forcing a path from Te Waka Tōhorā.

A message had to reach them first.

Erik's crashed craft could not fly.

Rere could not navigate an unknown route alone.

Then Piripi noticed a tiny side channel in the old map.

Not large enough for people.

Large enough for sound.

Or maybe a cicada.

Kiki landed on the map.

Everyone looked at her.

I shook my head.

We spent an entire lesson comparing route records from different communities. Their maps did not line up neatly because they had not been designed as one system. One marked water first, another stars, another stone pressure, another human travel. Overlaying them required translation rather than simply matching symbols.

That became a metaphor nobody needed to explain. Multicultural did not mean flattening different knowledge into one universal magical map. Cooperation required keeping differences visible long enough to understand how they connected.

“Absolutely not.”

Kiki clicked.

She had already volunteered.

Sending Kiki through an abandoned sanctuary route was a terrible idea.

We did it carefully.

That did not make it less terrible.

The side channel was too small for a person and too unstable for a normal message shell.

Kiki's Mīharo had always moved strangely through paths. She was partly cicada, partly something Aroha had awakened by accident, and completely convinced rules were optional.

Mere built a tiny recording bead for her to carry.

Erik spoke into it in his own language first, then English.

“I am alive. I reached Te Waka Tōhorā. We found the old two-gate route. If you receive this, hold Vardheim's gate at first light in three days.”

His voice shook only once.

I attached the bead gently beneath Kiki's wings.

“You come back.”

Click.

“That is not a promise.”

Click-click.

Hemi said, “Pretty sure that means promise.”

“You do not speak cicada.”

“Neither do you.”

Unfortunately, he had a point.

The route opened like a thin line of blue light.

Kiki flew through.

It closed.

I hated the next six hours.

Every minute felt wrong.

Erik paced.

Moemoeā made him eat.

Hemi pretended not to worry and failed.

At sunset the line flickered.

Kiki shot out and hit me in the forehead.

I had never been happier to be attacked by an insect.

The recording bead held a reply.

An older woman's voice spoke Erik's language.

He sat down hard.

“My aunt.”

He listened again.

Then translated.

Vardheim still stood.

Barely.

Their inner heating system had lost another section.

They could hold the old gate.

Three days.

First light.

At the end, his aunt said something longer.

Erik covered his face.

I waited.

Finally he said, “She said my mother thought I was dead.”

I sat beside him.

While Kiki was gone, Erik told me what his aunt sounded like when she was angry. He described his mother's soup, a bridge that iced over every winter and the room he shared with a cousin when he was younger. None of it was important to the rescue plan.

That was why it mattered.

Vardheim stopped being a failing sanctuary on a map. It became the place where Erik knew which floorboard squeaked and which neighbour gave children too much food. Saving a place meant saving ordinary life, not just systems.

No prophecy.

No world-saving speech.

Just one kid who had finally sent word home.

At first light, both gates answered.

Vardheim's side appeared as a pale blue line in the balancing chamber.

Our side glowed gold-green.

For the first time in generations, the two systems recognised each other.

Aroha's job was not to rip the route open.

My job was to help the lines meet without letting either side overwhelm the other.

Reweti handled structural flow.

Whaea Rina adjusted the woven guides.

Piripi watched water pressure.

Hemi held heat steady.

Moemoeā read changes in the path.

Erik stood at the centre with the old Vardheim marks in front of him.

“Now,” he said.

I placed one hand on the platform.

Gold lines rose.

On the other side, cold blue light moved toward us.

They touched.

The chamber shook.

Hemi increased heat.

“Too much,” Moemoeā said.

He lowered it immediately.

The path steadied.

A doorway formed.

Beyond it I saw snow.

Dark stone.

A woman crying.

Erik made a sound I had never heard from him and ran.

Grog grabbed his coat before he crossed.

“Slow.”

Erik looked ready to punch him.

Then the woman on the other side shouted his name.

Erik stopped fighting.

He stepped through carefully.

She pulled him into her arms.

The route held.

Everyone in our chamber exhaled at once.

Grog looked at me.

“Small team only.”

I nodded.

The council had agreed to an assessment mission.

Not rescue everyone.

Not open everything.

Go, understand, help build the safest next step.

Hemi hated how slow that sounded.

He came anyway.

Moemoeā too.

Piripi.

Grog.

Me.

I stepped through the gate.

Cold hit my face so hard I forgot every complaint I had ever made about winter in Aotearoa.

Erik laughed at my expression.

Behind him, Vardheim stretched into a dark frozen valley beneath a sky full of pale light.

Before I crossed, Mum's voice came through the Earth message route. Grog had told her what we were doing. She made me repeat the plan, the return conditions and the name of the adult responsible for me.

“You sound like Grog,” I complained.

“Excellent.”

Then she softened. “Go help. Do not go prove anything.”

That sentence travelled with me into Vardheim. I was not crossing to prove I deserved the title World-Shaper. I was crossing because another community had asked for help and we had finally found a way to answer without taking their choice away.

Beautiful.

And failing.

Book Four had become bigger than Te Waka Tōhorā.
