Work Text:
They chose the island because it looked impossible.
That was March’s official explanation, delivered with both hands pressed dramatically to the viewport glass while the planet below turned blue and violet beneath the Express.
Himeko’s official explanation was that the crew required a period of “non-mission recovery.”
Pom-Pom’s official explanation was that the Astral Express had passed all post-restoration inspections and deserved “a dignified scenic pause, conducted with appropriate respect for the train’s schedule.”
Caelus’s official explanation was, “Beach.”
Dan Heng said nothing, which was probably the wisest contribution anyone made that morning.
Welt, standing with a cup of tea near the rear of the party cart, looked from Himeko to Pom-Pom and then down at the planet rotating lazily beneath them. The archipelago scattered across the ocean shimmered in strange colours, beaches not white or gold but pale blue, like crushed glass softened by tide. In the shallows, streaks of coral showed through the water in deep red ribbons, staining the sea purple wherever sunlight hit at the right angle.
He looked at Himeko. Himeko looked serenely innocent. Pom-Pom looked aggressively busy with a clipboard.
Ah.
A conspiracy, then. Not subtle. Not even very well disguised, but, Welt thought, perhaps subtlety would have been wasted here.
The last few weeks had been full of repairs, inspections, negotiations, calibration, and the quiet, ongoing work of pretending nobody still woke too sharply when the train made an unfamiliar sound. The Express was whole again, yes. Better reinforced, technically. Its restored hull hummed underfoot with a steadier rhythm. Pom-Pom had personally approved every corridor, every lamp, every door seal, sometimes with tears in their eyes and sometimes with terrifying criticism. The crew had returned to familiar routines, more or less.
But “more or less” did a lot of work.
March still looked twice at exterior windows when the stars shifted oddly. Caelus hovered near Welt less obviously now, but not less often. Dan Heng had adjusted his patrol habits without saying he had done so. Sunday still watched echoes around the edges of conversations. Himeko’s smile remained warm, but the tiredness beneath it had not entirely lifted.
And Welt himself...
Well. He was getting used to being seen. An unpleasantly vulnerable process. Like being studied under a microscope by people who loved you and therefore had terrible judgment about how carefully they should look.
So, perhaps a beach was not a foolish idea.
Absurd, certainly. A crew of interstellar disaster magnets stopping on an uninhabited island for rest because the sand was pretty. Very rational. Humanity’s strategic genius in action, but not foolish.
Before anyone set foot on the surface, Himeko insisted on a full scan.
Welt supported this, which March described as “betrayal in old man stereo.”
Dan Heng took the portable sensor unit and went with him and Himeko to check the island first. Caelus protested being left behind until Pom-Pom threatened to assign him to polishing the furniture in the party cart. Sunday stayed aboard as well, watching the surface feed over Pom-Pom’s shoulder with quiet interest.
The island was small, perhaps a few kilometers across, with a crescent-shaped beach sheltered by dark rocks and low, wind-bent trees. No settlements. No predators above the size of a hand. No dangerous toxins in the water. No unstable energy signatures. No ruins, which was almost suspiciously generous of the universe. The red coral reefs sat far enough from the swimming area to avoid cuts, but close enough to colour the water in impossible gradients. The blue sand was soft, cool at first touch, and fine enough that Himeko immediately warned everyone not to track it back into the Express.
Pom-Pom had not even disembarked yet and somehow already looked personally offended by future sand.
Once the safety check was complete, the others arrived.
March ran down the beach first.
No walking. No dignified exploration. She launched herself onto the sand with a delighted scream and nearly faceplanted because blue sand, in a shocking betrayal of aesthetics, still behaved like sand.
Caelus followed at a jog, laughing at her until he tripped over the exact same slope and had to pretend he had done it intentionally.
Dan Heng stepped onto the beach with controlled caution, carrying towels, water, and the expression of someone who knew perfectly well he was about to be dragged into nonsense. Sunday came behind him, hat shading his face, gaze lingering on the purple shallows with something almost peaceful in his expression.
Welt and Himeko emerged last.
Pom-Pom stood at the open shuttle doorway and shouted, “No one brings wet sand inside! No one brings coral inside! No one brings unidentified marine organisms inside! This includes Caelus!”
Caelus turned around. “Why specifically me?”
Pom-Pom pointed at him. “You know why!”
He did not actually, or perhaps he did. The list of possible incidents was embarrassingly long.
The beach settled around them slowly. At first everyone behaved like people who had forgotten how to rest and had to reconstruct the process from damaged instructions.
Himeko spread a towel beneath the shade of a natural rock arch, then immediately refused to sit until she had checked the water line, sun exposure, emergency supplies, and everyone’s sunscreen application. March allowed herself to be inspected with exaggerated suffering. Caelus tried to escape. Dan Heng caught him by the collar without looking. Sunday, seeing the inevitability of the process, applied his own sunscreen with graceful resignation.
Welt did his own and then quietly handed Himeko the bottle when she raised one eyebrow at his exposed forearms.
“I was getting to it,” he said.
“Mm-hm.”
“That sounded skeptical.”
“It was.”
He did not argue. Himeko had very specific tones, and some of them were not worth challenging unless one actively desired consequence.
Eventually, Himeko lay back on her towel with sunglasses over her eyes, looking for the first time in weeks like she might actually intend to relax. Pom-Pom remained aboard for exactly seven minutes, then appeared on the beach dragging a small parasol and muttering about “supervision standards.”
Dan Heng went into the water first, because March accused him of being too dignified to swim. This was a tactical error. Dan Heng was perfectly capable of dignity in water. Worse, he was competent in it.
The ocean was warm, clear, and gently restless. The first wave rolled around his calves like silk. March splashed in beside him, gasped at the temperature, then immediately began kicking water in Caelus’s direction. Caelus retaliated with both hands, because apparently the human instinct to weaponize any nearby substance remained undefeated.
Dan Heng stepped aside before either attack touched him.
“Coward!” March shouted.
“Observant,” he replied.
Caelus cupped water between his palms and flung it at him. Dan Heng lifted one hand. A smooth arc of water rose from the sea in response and redirected the splash back into Caelus’s face.
March froze.
Caelus stood dripping, blinking seawater from his lashes.
Dan Heng’s expression remained perfectly neutral.
“That,” Caelus said slowly, “was cheating.”
Dan Heng turned away. “You initiated combat.”
“With hands! Like a civilized idiot!”
March pointed at Dan Heng. “He’s using powers!”
“I used a minimal defensive response.”
“You used magic plumbing!”
“It is not plumbing.”
“It was water, it moved, and now Caelus looks like a tragic wet raccoon. Plumbing.”
From shore, Himeko lifted one hand in lazy warning. “No drowning.”
“We are not drowning!” March called back.
“Yet,” Pom-Pom added grimly.
Meanwhile, Welt had been drawn into a quieter project.
Sunday had crouched near the drier stretch of blue sand, studying its texture with the seriousness of an architect selecting stone for a cathedral. Welt stood nearby, cane tucked beneath one arm, watching with mild curiosity.
“This sand compacts unusually well,” Sunday observed.
“High mineral density,” Welt said. “Fine grain, slight moisture retention. Good for structural work.”
Sunday looked up. “You have experience with sand construction?”
“I raised a child.”
Sunday considered this.
“Ah,” he said. “Of course.”
That was how the castle began.
Not a simple sandcastle. Naturally not. Nothing involving Welt Yang and Sunday could remain simple unless physically restrained by law enforcement, and even then, one suspected they would find a loophole.
At first, it was a central tower. Then a wall. Then a second tower. Then Sunday suggested a terrace system using shells as decorative arches. Welt pointed out that the shells had irregular curvature and might destabilize the upper walkways unless embedded properly. Sunday, instead of being deterred like a normal person, looked pleased.
Within an hour and a half, they had created something that no longer qualified as a sandcastle and had begun approaching civic planning.
Blue towers rose in tiers. Red coral fragments, collected only from loose pieces already washed ashore because Himeko had given them both a look about damaging living reef, became window frames and balustrades. A moat curved around the outer wall, fed by a tiny channel Welt carved with the end of his cane. Sunday shaped staircases, courtyards, and a ridiculous number of ornamental bridges.
Welt, despite repeated claims that he was “only assisting,” was clearly invested.
March noticed from the water.
She shaded her eyes and stared at the shore. “Are they building Penacony?”
Caelus followed her gaze. “No. Too stable.”
Dan Heng looked over once. “The western wall has better defensive placement than most real fortifications.”
March turned to him. “That is not normal commentary for a beach day.”
“It is accurate.”
“You are all hopeless.”
On the sand, Sunday tilted his head, studying the latest tower. “This section lacks vertical emphasis.”
Welt hummed thoughtfully. “A spire?”
“Perhaps three.”
“Ambitious.”
“The structure can support it.”
“Only if we reinforce the base.”
Sunday looked at him. Welt looked back. Both reached for wet sand at the same time.
Himeko, watching from behind her sunglasses, smiled faintly. It was good to see. Ridiculous, yes. Two men with histories heavy enough to crush architecture as a concept, crouched in blue sand arguing silently about miniature spires, but good.
The day warmed.
The sea brightened. Purple shadows moved over the shallows where red coral bent the light. The empty island remained empty except for them, and slowly the crew forgot to listen for alarms.
That was the real rest.
Not stillness. Not sleep. Just forgetting, briefly, that the universe had teeth.
Caelus was the one who ruined the peace, which was to say improved it.
He had been splashing waist-deep in the water, locked in an increasingly unfair contest with Dan Heng, who continued to redirect waves with tiny movements of his hand and an expression of false innocence. March had already shouted “cheater” fourteen times, which Caelus felt showed admirable restraint.
Then inspiration struck.
It had the usual problem of Caelus’s inspirations, namely that it arrived fully confident and only partially examined.
He turned toward the shore, cupped both hands around his mouth, and shouted, “Mr. Yang!”
Welt looked up from carving a narrow bridge into the sandcastle. “Yes?”
Caelus pointed dramatically at Dan Heng. “Can you make us water pistols? It’s unfair that only Dan Heng has water-based powers. He’s cheating!”
Dan Heng closed his eyes for one long second.
March gasped. “That is genius.”
“It is escalation,” Dan Heng said.
“It is justice,” Caelus corrected.
Onshore, Welt blinked. For a moment, he simply looked at Caelus.
Not confused. More like his mind had arrived at the request, circled it once, and found it unexpectedly tender. He was still getting used to this. To them knowing. To his abilities becoming not merely emergency armor, not battlefield necessity, not carefully hidden threat, but something a child could ask of him on a beach.
Water pistols.
He had used the power of Reason to recreate weapons, cities, mechanical armies, his own body. He had held a train together in deep space. He had negotiated with generals and restored mechanisms older than some governments and now Caelus wanted water pistols because Dan Heng was cheating at splashing.
The absurdity of it made something in Welt’s chest loosen. He looked to Himeko first. She lowered her sunglasses just enough to meet his eyes. There was a question there. Not can you. Not should you. Gentler than that.
Are you alright with this?
Welt considered. Then nodded once.
“Very well,” he said.
March threw both arms up. “Victory!”
Dan Heng muttered, “This is how arms races begin.”
Welt stood, brushing blue sand from his hands. Sunday sat back on his heels and watched with unmistakable fascination.
The constructs formed small this time.
No grand flare, no red undertones, no terrible storm-light. Just neat gold geometry folding into shape above Welt’s palm. Curved reservoirs. Pump systems. Pressure valves. No sharp edges. Three water pistols formed in sequence, each brightly translucent, sized to fit comfortably in hand.
Welt walked them down to the waterline.
Caelus accepted his like a sacred blade.
March took hers with reverence. “I have never loved technology more.”
Dan Heng looked at the third one Welt offered him. “I do not need one.”
“No,” Welt said. “But it may preserve diplomatic balance.”
Dan Heng considered that, then accepted it.
Caelus immediately shot him in the chest.
Dan Heng looked down at the splash mark.
Then he raised his pistol and shot Caelus directly in the forehead.
March screamed with laughter and opened fire on both of them.
The next ten minutes were chaos. Glorious, undignified chaos.
March had terrible aim but astonishing enthusiasm. Caelus used rocks as cover despite the fact that they were waist-deep in open water and this was not a tactical exercise unless one had recently lost all perspective, which, fair enough, he had. Dan Heng was devastatingly accurate and became the clear enemy of justice within three minutes. March and Caelus formed an alliance. The alliance lasted thirty-two seconds before March shot Caelus in the ear by accident and he declared betrayal.
Welt returned to the sandcastle, smiling despite himself.
Sunday watched the battle with the expression of someone discovering an anthropology field study in real time. “Is this a common recreational practice?”
“For children, yes,” Welt said.
“For these children specifically?”
“Also yes.”
Sunday looked at Caelus, who had just shouted “For the Express!” and charged through waist-high water directly into Dan Heng’s counterattack.
“I see.”
The water pistols lasted almost an hour before March, dripping and breathless, came back up the beach with the same expression that had doomed many adults across many worlds.
“Mr. Yang.”
Welt did not look up from the castle’s outer gate. “No.”
“You don’t even know what I’m going to ask.”
“I have context clues.”
Caelus appeared behind her, equally wet and equally guilty. “What if the water pistols were bigger?”
“No.”
“What if they had rotating jets?”
“No.”
“What if,” March said, eyes widening with tactical innocence, “we had water bikes?”
Welt paused.
Himeko, from her towel, said without moving, “Welt.”
“I have not agreed.”
“You are thinking about it.”
“Thinking is not a crime.”
“In this crew, it often precedes one.”
March clasped her hands under her chin.
Oh no, Welt thought. Not that.
She widened her eyes.
Caelus, shameless little opportunist, copied her with less skill but more desperation.
Sunday, still crouched beside the castle, tilted his head. “They are attempting emotional manipulation.”
“Yes,” Welt said.
“Is it effective?”
Welt looked at March.
March looked back with the tragic expression of a maiden in an opera, if the maiden wanted a recreational aquatic vehicle.
Welt sighed.
“Unfortunately.”
Himeko covered her face with one hand.
Dan Heng, from the water, called, “This is unwise.”
March spun around. “Nobody asked you, Sea Tyrant!”
“I am trying to prevent escalation.”
“You lost that war when you weaponized waves.”
“I redirected splashes.”
“Tyrant language.”
Welt created two water bikes. Then, after three seconds of Caelus and March both staring at the number, he created a third for Dan Heng and a fourth in case Sunday wished to try. He did not, at first. Then March shouted that he could ride slowly, and Sunday looked at the water, then at the bike, then at Welt.
“It is stable?”
“It is extremely stable.”
“Can it tip over?”
“With sufficient effort.”
Caelus raised a hand. “I can test that.”
“No,” said four people at once.
The bikes were less mechanical than they looked, more like sleek floating frames with water-powered propulsion and automatic balance correction. Welt had very deliberately built speed limits into them. He did not mention this because Caelus would take it personally and attempt to locate them.
They spent the next hour racing along the shallows.
March shrieked every time she accelerated, regardless of speed. Caelus leaned too far into turns and almost defeated the balance system through sheer commitment to bad decisions. Dan Heng rode like someone who had instantly understood the mechanics and found them mildly acceptable. Sunday began cautiously, then slowly relaxed, coat discarded on shore, hair blown back by sea wind, expression opening into something younger than his usual careful composure.
That alone made the entire foolishness worthwhile.
Welt stood near the waterline, one hand shading his eyes, watching them loop around the safe zone he and Himeko had marked earlier.
Himeko came to stand beside him.
“You are spoiling them,” she said.
“Yes.”
“No denial?”
“It would be inefficient.”
She smiled. “At least you know.”
March swept past on a water bike, waving one hand wildly. “Mr. Yang! Look!”
“I am looking.”
She nearly turned too sharply and yelped as the bike corrected itself.
Himeko glanced at him.
“Built-in safety?”
“Many layers.”
“Good.”
A pause.
Then Himeko added, “Can it support two people?”
Welt looked at her.
She had sunglasses pushed onto her head now. Her hair was loose from its usual style, wind moving through it. She looked relaxed, warm, amused, and only slightly dangerous.
“I thought you were sunbathing,” he said.
“I was. Now I am curious.”
“Curiosity has caused a great many problems aboard this train.”
“Mm. And several nice afternoons.”
That was unfair. He made her a water bike.
Naturally, the moment Himeko joined, the entire dynamic shifted. Not because she was the fastest. Because she was elegant. She rode the thing as if she had been born doing it, cutting through purple shallows with easy confidence while March shouted accusations of hidden practice.
“Himeko!” March cried. “You said you hadn’t done this before!”
“I haven’t.”
“Then why are you good at it?”
“Age and betrayal,” Caelus said, passing badly behind her.
Himeko laughed and sprayed him with a neat fan of water from her turn.
Welt, abandoned onshore with Sunday and the increasingly elaborate sand metropolis, returned to construction. For approximately twelve minutes.
Then March came back.
“Mr. Yang.”
“No.”
“Water slopes.”
“March.”
“Just one.”
“No.”
“Two?”
“That is worse.”
“They don’t have to be big.”
Caelus dragged his bike onto shore behind her. “They should be big.”
Dan Heng, arriving more sensibly, said, “They should not exist.”
Sunday looked at the nearly completed sandcastle, then toward the beach slope leading into the water. “A temporary slide structure could be safe if properly angled.”
Dan Heng stared at him. “Do not encourage this.”
Sunday seemed faintly amused. “I am merely observing.”
“You are enabling.”
“I have been told I should participate more in group activities.”
“Not like this.”
Welt looked at Himeko.
Himeko was back on her towel, pretending not to listen.
“Himeko,” he said.
She did not open her eyes. “I am off duty.”
“That is not true.”
“It is emotionally true.”
“Unhelpful.”
“Build the slide, Welt.”
Betrayal again.
It became, as these things always did, larger than originally proposed.
The first water slope was modest. A smooth construct ramp starting from a gentle rise in the sand and curving into the shallows, water circulating over it in a steady sheet. Welt tested the angle. Dan Heng inspected the landing zone. Himeko checked the depth. Pom-Pom, who had finally joined them properly under a parasol, demanded posted usage rules.
March went first.
She flew down the slope, hit the water with a splash large enough to soak Caelus, and surfaced screaming with delight.
“AGAIN!”
Caelus went second and tried to stand at the end. This went exactly as badly as expected.
Dan Heng went third only after March shouted that he was afraid. He slid down with perfect balance, entered the water smoothly, and emerged without his hair even fully wet. Everyone booed him.
Sunday hesitated for nearly five minutes before trying it. He sat at the top of the slope, hands placed carefully at his sides, expression intensely focused.
“It is safe,” Welt said gently.
“I know.”
“You do not have to.”
“I know that too.”
Sunday drew a breath. Then pushed himself forward.
The slide carried him down faster than he expected. His eyes widened, his composure vanished for one fleeting, priceless second, and then he hit the water with a splash that sent March into hysterics.
When he surfaced, soaked and blinking, there was a shocked laugh already escaping him.
A real laugh.
Not polished. Not elegant. Not controlled. Just joy, startled out of him before guilt or thought could catch it.
March clapped so hard she nearly fell over. Caelus whooped. Himeko smiled behind her hand. Even Dan Heng looked openly pleased, which, in Dan Heng terms, was basically confetti.
Sunday pushed wet hair out of his face, laughing still, and looked at Welt.
“That was undignified.”
“Yes,” Welt said.
Sunday’s smile widened. “Again.”
Ah.
There it was. The death of restraint.
The slide became three slides. Then a curved one. Then a twin-race one because March claimed Caelus had cheated by “being heavier and therefore more gravity-adjacent,” which was not how physics worked, but apparently facts were seasonal. Welt built supports, flow controls, soft landing zones, self-dissolving edges, and an automatic stop if anyone approached at a dangerous angle. He refused to make anything taller than the rock arch.
March called him cruel.
Caelus called him reasonable in a disappointed voice.
Dan Heng called him wise.
Pom-Pom called everyone reckless and then, after several minutes of watching with enormous moral conflict, demanded a conductor-sized slope.
Welt built it immediately.
Pom-Pom went down once. Then again. Then six more times.
Nobody commented. Survival instincts, finally.
By late afternoon, the beach had become a temporary aquatic amusement park powered by the former Herrscher of Reason and the shameless demands of emotionally recovering young adults. The sandcastle had expanded into a fortified coastal capital. Water pistols lay abandoned near the towel pile. The bikes bobbed gently in the shallows. Slides arched in shimmering gold and translucent blue, harmless, temporary, ridiculous.
Himeko eventually gave up any pretence of supervision from afar and joined properly.
She raced March down the twin slides and won. March demanded a rematch. Caelus tried to interfere and got hit by both of them at once. Dan Heng stood too close to the splash zone and received the consequences with grim acceptance. Sunday, who had started the day building towers, ended it riding water bikes with his sleeves rolled up and laughing more than any of them had heard before.
Welt watched them all from the shore at one point, cane planted in the blue sand, salt wind on his face.
His constructs gleamed in the sun. No fear in their eyes this time. That was the thing that stayed with him.
They knew now. Not everything, but enough. Enough to know the power was not ordinary. Enough to know it could build shields, weapons, limbs, trains. Enough to be afraid of what it cost.
And still March asked him for toys.
Caelus complained about fairness.
Sunday trusted his slide.
Dan Heng inspected his safety measures and then used them.
Himeko let him make something useless and joyful.
It was a strange mercy, being asked to use an old battlefield power for play. A ridiculous mercy. A precious one.
“Mr. Yang!”
He looked up.
March stood near the top of the largest slide, dripping wet, sunburn beginning across her shoulders despite repeated sunscreen, grinning like the universe had not once tried to eat their train.
“Watch this!”
“I am watching,” Welt called.
She launched herself down the slide with a triumphant yell, hit the water, vanished, and surfaced with both arms raised.
Caelus followed immediately after, collided with the splash she had left behind, and emerged sputtering. “Sabotage!”
“You sabotaged yourself!” March shouted.
Dan Heng, floating nearby, said, “That is often the case.”
Caelus splashed him.
Dan Heng splashed back without moving.
“Cheater!”
“You have a water pistol.”
“I lost it!”
“That seems like poor logistics.”
Sunday, passing slowly on a water bike, said, “I believe it is under the left towel.”
Caelus stared. “You knew that and didn’t tell me?”
“I assumed you enjoyed the drama.”
“I do, but that’s not the point.”
Himeko laughed from the shallows, head tilted back toward the sun.
Pom-Pom sat proudly at the foot of their tiny slide, soaked from hat to shoes, declaring that the slope angle was “acceptable, though requiring future refinement.”
Welt felt himself smile. Not the small polite smile. Not the reassuring one. Not the tired one meant to keep others from asking questions.
A real one. Unpractised. Quiet. His.
By evening, everyone was ruined.
There was no elegant way to put it.
March had blue sand stuck to one side of her face and a sunburn across her nose. Caelus looked like a drowned animal that had discovered happiness through poor decision-making. Dan Heng’s hair had finally surrendered to seawater, which March considered a major victory for justice. Sunday’s clothes were salt-streaked, his dignity had not survived the third slide run, and he looked better for it. Pom-Pom was wrapped in a towel twice their size, insisting they were not tired while visibly nodding off. Himeko’s shoulders were pink from sun despite her carefulness, and her hair smelled of salt.
Welt was also sunburned.
Mildly.
This was apparently unacceptable.
March noticed while they were packing up.
“Mr. Yang! You’re red.”
Welt looked down at his forearm. “A little.”
“You forgot to reapply sunscreen!”
“I was occupied.”
“Building a water empire is not an excuse.”
Caelus leaned over. “It kind of is.”
“No, it isn’t!”
Himeko, wrapping her towel around her shoulders, gave Welt an amused look. “You made sure everyone else was protected.”
“I miscalculated duration.”
Dan Heng said, “That is a concerning sentence from you.”
Sunday, still squeezing water from his sleeve, added, “Especially after today’s engineering display.”
Welt adjusted his glasses, which were somehow still clean because some miracles were small and deeply irritating. “I assure you the sunburn is not structurally significant.”
March pointed at him. “No technicalities. Aloe when we get back.”
Pom-Pom lifted their head from inside the towel cocoon. “No sand inside first.”
“Yes, yes,” Caelus said. “Rinse station. We remember.”
“You do not remember. Pom-Pom remembers for you.”
“Harsh but fair.”
Before they left, they stood together for a moment at the edge of the water.
The sun had lowered toward the horizon, turning the purple sea darker, richer. The red coral glowed beneath the surface like banked embers. The blue sand held footprints everywhere: running lines, slide marks, collapsed moat channels, the deep groove where Caelus had wiped out beside the water bikes, tiny Pom-Pom tracks near the conductor slide.
Welt dismissed the constructs slowly.
The water slides unravelled first, gold dissolving into sparks that faded before touching the sand. The bikes vanished. The water pistols, collected and counted under Pom-Pom’s strict supervision, disappeared last. The sandcastle remained.
Sunday looked at it. “You are leaving that one?”
“It is made of sand,” Welt said. “It will return to the beach on its own.”
March sniffed theatrically. “Our kingdom.”
Caelus put a hand over his heart. “Gone but not forgotten.”
Dan Heng looked at the absurdly elaborate castle. “The tide will reach it in approximately three hours.”
“Traitor,” March said.
“That is not betrayal. It is oceanography.”
Himeko slipped her sandals back on and looked at the castle with fond amusement. “Then it gets three more hours.”
Pom-Pom yawned hugely and tried to disguise it as a cough. Nobody was fooled.
They returned to the Express in slow, tired procession.
Rinsed, inspected, scolded, and finally allowed inside by Pom-Pom, they collapsed into the party car with the particular boneless exhaustion that came only after sun, salt, laughter, and too much swimming.
March fell asleep across two seats within minutes, hair still faintly damp. Caelus sat on the floor beside the bench and claimed he was not asleep while already losing consciousness. Dan Heng covered him with a towel without asking. Sunday curled into a chair near the window, quieter now but not withdrawn, watching the planet’s curve with a softness in his face. Himeko made tea, because apparently even beach exhaustion had rituals. Pom-Pom, still towel-wrapped, sat at the conductor’s console and pretended to review departure timing until their head tipped forward.
Welt stood near the window for a while.
The restored Express hummed beneath his feet. Not broken. Not silent. Not memory alone.
Home.
Behind him, his crew slept or nearly slept, sunburned, salt-crusted, and absurdly happy.
He touched one hand lightly against the window frame. The train answered with its steady vibration.
For once, no one needed saving.
No crisis waited in the next room. No general across a table. No shell to hold. No body to rebuild. No secret forced loose by fever or fear.
Only the quiet aftermath of a day wasted beautifully.
Himeko came to stand beside him and handed him a cup.
“You look pleased with yourself,” she said.
“I created several recreational devices and one temporary fortified city. I believe the day was productive.”
She smiled. “You made them happy.”
Welt looked back at the sleeping heap that constituted the younger generation of the Astral Express. An alarming species, frankly. Loud. Fragile. Reckless. Too easy to love.
“They made it easy,” he said.
Himeko’s expression softened.
Outside, the island turned slowly under sunset, blue sand cooling beneath the tide, red coral darkening under purple water, and the castle waiting for the sea.
Inside, the Astral Express carried salt, laughter, sunburn, and a little more healing than anyone had known how to ask for.
