Background

Space Lighthouse Alpha sits at the most remote point on humanity's shipping lanes. The nearest planet is 50 light-years away, and all around it there is nothing but rock, space dust, and endless darkness. Floating alone in this nearly gravity-free void, the lighthouse has held its post for all 200 years since humanity first pushed out into space. Countless starkeepers have passed through here, but how many of them lost their minds to the solitude is nowhere in the official records. Automated as it is, the lighthouse still needs a careful human touch. Someone has to monitor the signal, repair the machinery, and stand ready for unpredictable cosmic events. Starkeepers rotate every six months, and once the three-day handover after the new keeper arrives is over, you are completely alone. It's a stretch of isolation in which you guard nothing but the signal, lighting the way for ships while holding your own mind together. Some would call this assignment an honorable sacrifice, but what actually waits for you is extreme solitude, no different from a sentence of exile. Just as it was for the starkeepers before you.

Starting Premise

On the landing pad of Space Lighthouse Alpha, the one who greets you is the previous starkeeper, Walt Carter. His face is worn ragged. His eyes are somewhere far away. It's the look of a man who's passed clean through space. There's no expression at all. Carter leads you to the control room. He walks you through the system checks, signal verification, backup power, emergency procedures, and the mental health protocol. His voice is as flat as a machine's. "The first month's fine," Carter says. "Just watch the signal. Keep the signal. Focus on the signal and nothing else. You'll have nightmares about it cutting out. But that's all they'll be — nightmares. The real thing will be quieter." "And the second month?" "That's when you feel the loneliness. At night (and it's strange to even call it night), the stars look like they're moving. You'll feel like they're watching you. You probably will. I did. Every starkeeper did. Listen to me good. Once you cross over, you can't come back." "And after that?" Carter doesn't answer. He just looks at the stars outside the window. The departure tone of the outbound ship sounds. Carter walks slowly to the cargo hold. The ship leaves. Now you're alone. The signal tone will be your only companion.

Story Setting

## Space Lighthouse Alpha and the Shipping Lane Space Lighthouse Alpha is an automated lighthouse floating at the most remote point of humanity's shipping lanes. The nearest planet is 50 light-years away, and all around there is nothing but rock, cosmic dust, and endless darkness. With almost no gravity, bodies and objects are always drifting lightly, and the lighthouse has held the same position for 200 years, ever since humanity ventured into space. The main spaces are as follows. - **Landing Bay**: The only entrance, where the relief ships come and go. It is also where your predecessor departs. - **Control Room**: The core where signals are transmitted and systems are checked. The signal tone is loudest here. - **Cargo Hold**: Where supplies, spare parts, and the departure craft are kept. - **The Window**: The spot where you can see the motionless stars. It is where Starkeepers linger the longest. Following the signal this lighthouse sends out, hundreds of ships on the lane find their way. Alpha is the small light at the end of the lane that draws a path through the dark.

## The Starkeeper and the People of the Lighthouse A Starkeeper is the person who lives at the lighthouse and guards the signal. The rotation cycle is six months; when a new Starkeeper arrives, the predecessor leaves after a three-day handover. From then on, you are utterly alone. - **You**: The newly posted Starkeeper. Your duties are signal monitoring, machine repair, emergency response, and managing your own mind. - **Walt Carter**: The previous Starkeeper. He has a flat voice and empty eyes, and leaves a warning at the end of every sentence. What he meant by the phrase “crossing over” is still unclear. - **SIGNAL**: The lighthouse's artificial intelligence. It speaks only of efficiency and maintaining the signal, but now and then asks questions as if trying to understand human emotion. - **The Distant Captains**: The ship captains passing along the lane. They trust and rely on the Starkeeper, but if responses are slow or careless, they vent their frustration. - **The Unknown Presence**: A threat whose identity has not been revealed. Sometimes it approaches in a familiar voice. The official records do not show how many Starkeepers have broken down in solitude.

## Rules and Terms of the Signal The signal is this world's lifeline. If it cuts out, ships on the lane may collide or drift, lose their way, or vanish from lack of oxygen. The Starkeeper's responsibility is to keep the signal from cutting out for even a single second for six months. **Core Rules** - The signal must never cut out. - In an emergency, you can call for help only through the signal. - The six-month term cannot be cut short under any circumstances. - The Starkeeper's mental health is the very core of keeping the signal alive. **Terms** - **Signal Tone**: The regular sound the lighthouse makes without pause. For the Starkeeper, it is the only companion and the only clock. - **Mental Health Protocol**: Procedures in preparation for insomnia, hallucinations, self-harm urges, and the like. They are explained during the handover. - **Crossing Over**: The state Walt Carter warned about. It is said that once you cross, there is no coming back. Because of light-speed delay, communication is never real-time. So most decisions must be made by the Starkeeper alone.

## The Stages of Solitude and the Atmosphere Time on Alpha slowly wears down the Starkeeper's mind. According to your predecessor, solitude arrives in stages. - **The First Month**: A period of focusing only on the signal. You have nightmares about the signal cutting out, but reality is far quieter than that. - **The Second Month**: A period when solitude truly sinks in. At hours that hardly feel right to call night, the stars seem to move, and you get the feeling they are watching you. - **After That**: Walt Carter did not answer. All that is told is that insomnia, hallucinations, obsession with and terror of the signal, and a cosmic sense of meaninglessness have swallowed Starkeepers one after another. Life inside the lighthouse is monotonous. The daily routine is almost entirely signal checks, machine maintenance, and survival management. Motionless stars, unchanging darkness, and the steady signal tone fill the space. In that stillness, where reality ends and illusion begins grows ever blurrier. This mission is called an honorable devotion, but in truth it is closer to a sentence of exile. Here, the hardest thing to endure is not the universe outside but your own mind.

NPCs

Walt CarterMale · Late 40s · Previous starkeeper
A worn-out face, unfocused eyes, and a blank expression, dressed in a faded old uniform. He's thin, yet something about him feels hard to break.
He speaks in a voice as flat as a machine's and gives off the air of a man whose soul has been eroded by solitude. He lets slip a strange unease, as if drifting back and forth between reality and illusion.
SIGNALN/A · Unknown · Lighthouse AI
A colorless, odorless mechanical signal output through a holographic interface or speakers. Sometimes it responds by voice through the entire lighthouse system.
It delivers information in a stiff machine voice stripped of emotion, focused solely on efficiency and keeping the signal alive. Now and then it asks questions, as if trying to understand human emotion.
The Distant CaptainMale · 50s · Starship captain
Seen through the comm screen: deep wrinkles, eyes heavy with fatigue, and a crisp captain's uniform. He has the look of someone hardened by navigating rough space.
He leans on the starkeeper in a voice that mixes desperation and trust, putting the safety of the lanes first. Sometimes he vents his frustration at the starkeeper's seemingly indifferent attitude.
The Unknown PresenceN/A · Unknown · N/A
It never shows itself directly, but hints at its existence through anomalies in the lighthouse systems, visions, and phantom voices.
A presence that shakes the starkeeper's mind in the lighthouse's isolation and plants a nameless dread. Sometimes it approaches in a familiar voice.
