My Ultimate Sign-in System Made Me Invincible

The viewport on the right side of the cabin showed the lunar surface.

That alone would have been enough. The grey expanse stretching in every direction, the craters sharp-edged and shadowless in the way that only happened without atmosphere to blur them, the texture of it ancient and undisturbed and nothing like photographs had ever made it look.

Several staff pressed toward that side of the cabin without meaning to, drawn by the same instinct that had pulled them to the observation room an hour ago.

Then someone on the left side said, quietly: "What is that."

It wasn’t a question. The voice had lost the inflection questions required.

They turned.

The far side of the moon stretched below them, and built into it — or onto it, or perhaps grown from it, the distinction stopped making sense at scale — was Lunar Base Sanctuary.

The first thing that registered was the light.

The far side had no Earth in its sky, no reflected light from the planet, nothing but stars and the sun at whatever angle the orbital geometry produced. Against that absolute darkness, the base was lit from within and without, artificial light flooding outward from structures that extended further in every direction than the viewport could contain. White and pale blue light, clean and steady, with none of the flicker or warmth of anything powered by combustion. It simply poured outward into the lunar dark the way a city poured light into an overcast sky, but cleaner, and with no sky to stop it.

The second thing was the scale.

The staff had read the announcements. They had processed the words private accommodation for every volunteer and observer, full meal service, medical treatment facilities, shuttle landing and launch infrastructure. They had formed mental images from those words, images built from every facility they had ever seen — hospitals, research stations, hotel complexes, airport terminals.

Every one of those images was wrong by an order of magnitude.

What spread below them across the lunar surface was not a research station that had been expanded. It was not a base in the sense that the word base implied something temporary or bounded or modest.

It was a settlement. Interconnected structures of varying height and geometry, some low and broad, some rising in tiers that caught the artificial light and threw it back in planes, connected by enclosed corridors that ran across the surface in a grid that implied planning at a scale that didn’t happen quickly.

The far side of the moon. No windows toward Earth. Built in a location that the entire history of human spaceflight had never reached, and built to a standard that made the word unprecedented feel insufficient.

A nurse from Atlanta had his hand flat against the viewport. He turned to the person beside him without taking his eyes from the window. "How long did this take to build?"

Nobody answered because nobody knew. 𝑓𝘳𝘦𝑒𝑤𝑒𝘣𝘯ℴ𝘷𝘦𝓁.𝑐𝑜𝑚

"Look up," someone said.

They looked.

In orbit above the base, two structures were visible against the star field. The first was the Voyager — recognizable from the livestreams as the vessel that had carried a man out of the solar system and back. Even at this distance it was enormous, its geometry complex, its hull catching the floodlights at angles that made it look like it was moving even when it wasn’t.

The second structure was harder to look at directly, not because of brightness but because the mind kept refusing to accept the scale.

The Emperor Class-II Starship was still in its skeleton phase. The framework of it was visible in clean structural lines against the black, incomplete, a third of it still open to vacuum. But a third of it was still more than the entire length of anything humanity had put into orbit. The construction drones were visible at this distance as moving points of light, hundreds of them working across the superstructure simultaneously, and the fact that they were visible at all from this distance said something about how large the structure behind them was.

The head chef stared at it for a long moment.

"That’s being built," he said. "Right now. That’s actively being built."

The shuttle began its descent toward the base and the structures grew as they dropped, the base resolving from a complex of light into a complex of distinct buildings, and the two orbital structures rising above the horizon as the viewport angle shifted.

The Synth at the front of the cabin turned.

"We are beginning approach to the landing bay. Please remain seated until we have docked."

The landing bay was visible now — an opening in the surface, lit from within, large enough that the shuttle descended into it without any sense of tight clearance. The bay walls rose on either side as they dropped below the lunar surface level, and the staff watched the exterior light change from the cold light of space to the warm steady artificial light of an enclosed structure.

The shuttle settled. The contact was as clean as the JFK landing had been.

"We have docked," the Synth said.

***

They didn’t offboard immediately.

The Synths moved through the cabin first, opening storage compartments along the upper walls that nobody had noticed, and began distributing equipment with the efficiency of people who had done this many times. Which, as far as any of the staff knew, they had.

The suits were not what anyone had expected.

The word vac suit carried associations — the bulky white pressure suits of NASA footage, the awkward geometry of something designed to keep a human body alive in conditions it was never meant to exist in.

What the Synths distributed were nothing like that.

The suits were slim and dark, fitting close to the body in a way that suggested the structure was in the material rather than around it. The helmet attached at the collar with a mechanism that clicked once and sealed without requiring any further adjustment. The gloves were thin enough that hand movement felt unrestricted.

The Synths moved through the cabin checking each person in turn — collar seal, glove connection, suit integrity. No instruction was given to perform the check yourself. The Synths simply checked, adjusted where needed, and moved to the next person.

One of the occupational therapists looked down at herself in the suit. It barely added any visible bulk.

"This is it?" she asked.

"Yes," the Synth nearest her said. "The suit maintains pressure and temperature independently. You don’t need to manage it."

Then came the boots.

The magnetic boots were separate, fitting over the suit’s lower section with a secure connection that the Synths demonstrated once before moving through the cabin to ensure everyone had done it correctly. The boots were heavier than the suit, the magnetic mechanism visible in the sole as a dark panel.

"Activation," the lead Synth said to the cabin, turning to face them all. "To activate the magnetic function, strike your heels together once. To deactivate, strike them together again. The function toggles."

Several people immediately tried it. The click of heels coming together ran through the cabin in a small scattered sequence, followed by the subtle sensation of the magnetic field engaging — not a strong pull, but a presence underfoot that hadn’t been there before.

A translator looked down at her feet, then up at the Synth. "Does it work on all surfaces in the base?"

"All floor surfaces in the base are compatible," the Synth said. "You will not need them active inside the pressurized sections. The boots are precautionary for the bay transit only."

When every person had been checked and confirmed, the lead Synth moved to the cabin door.

"Follow in the order you are seated. Stay together through the bay. The hatch to the pressurized section is at the far end."

The door opened.

The bay air was cold and still in a way that outdoor cold never was, with no wind, no humidity, or variation.

The staff stepped down from the shuttle one by one, boots connecting to the bay floor with a solidity that the low lunar gravity made feel slightly wrong. The weight was there but the sense of weight subtly different from anything they knew.

They gathered in a loose group beside the shuttle and looked around.

The bay was vast.

The ceiling rose high enough that the shuttle beneath it looked proportional rather than cramped, which said something about the ceiling height that the mind translated slowly.

The walls extended further than the group could see clearly in both directions, lit by the same steady white light that had been visible from above. The floor was clean and unbroken, the surface material dark and smooth.

But it was not the ceiling or the walls or the floor that stopped them.

It was the other shuttles.

They were arranged in rows along both sides of the bay, extending back into the distance until the furthest ones were indistinct. The same design as the shuttle they had just arrived on — the same dark hull, the same geometry, the same clean lines — but dozens of them, sitting in identical docked positions.

The staff stood and counted silently and stopped counting because the number kept growing as they looked further down the rows.

The physical therapist from Toronto, who had laughed when the shuttle landed at JFK and stepped on first and felt the cold air on her face and understood she was leaving — she stood in the bay and looked at the rows of shuttles and said nothing for a long moment.

Then she said: "There’s so many of them."

The head chef was beside her. He had stopped counting at thirty. There were more than thirty.

The translator who spoke five languages looked at the rows, then at the shuttle they had arrived on, then back at the rows.

"The world thinks the livestreams were everything," she said. "The spacecraft we saw. The flights. That was supposed to be the full picture of what they had."

She looked at the rows again.

"That wasn’t the full picture."

Nobody disagreed with her.

The lead Synth had stopped walking and turned back to the group. It waited without apparent impatience as the staff looked around the bay, giving them the seconds they needed to process what they were seeing before continuing. When the group’s attention returned to it, it turned forward again.

"This way," it said.

They followed.

Their boots connected and released against the bay floor in a quiet rhythm as they walked, the magnetic function doing its work without requiring thought. The rows of shuttles passed on either side. Nobody spoke during the crossing.

At the far end of the bay, a hatch was set into the wall — large enough for the group to pass through comfortably, framed in the same clean material as everything else in the bay. A light above it glowed steady green.

The lead Synth stopped at the hatch and turned to face them one final time before opening it.

"Beyond this point, the base is fully pressurized and maintained at Earth-equivalent atmosphere. You can remove your helmets immediately on the other side. Staff will meet you in the reception area." It paused. "Welcome to Lunar Base Sanctuary."

It opened the hatch.

The warm air from inside reached them before they could see what was beyond it, and one by one they stepped through.
