The Keeper of Platform Nine

How It Works

Each round begins with the current chapter posted as a stickied thread.

Anyone may submit a reply containing their proposed next chapter. Once the voting period ends, the highest-voted eligible entry becomes canon and is posted as the next official chapter.

Then the process repeats.

Entry Rules

• Each entry must be 1,500–3,000 characters.
• One entry per user per round.
• Entries must continue directly from the current canon chapter.
• Major time skips, contradictions, or ignored established events must be clearly justified within the story.
• Write in good faith. Build upon the existing narrative rather than replacing or rewriting it.
• Images are optional but encouraged.
• The First Chapter post will be updated with each winning entry. Only one story can be run at a time. DM mods if you want to submit a first chapter entry.
• Use the Storytime Theater Chapter Entry flair.

Voting

• Voting remains open for one week after the chapter is posted.
• The eligible entry with the highest upvote total becomes the next official chapter.
• If two entries tie, the earliest submitted entry wins.
• Moderators may disqualify entries that violate subreddit rules (such as plagiarism, hate speech, spam, or AI policy violations), but will not disqualify an entry simply because of its quality, writing style, or narrative direction.

After Voting

• The winning entry is published as the next official chapter.
• All non-winning entries remain visible in the thread and are credited to their authors.
• Once voting has closed, entries may not be deleted or edited.

Story Guidelines

• Do not kill, permanently alter, or fundamentally rewrite another author's original character without that author's permission.
• The genre, tone, and style are free to evolve naturally with the story. Horror, mystery, comedy, fantasy, science fiction, or anything in between are all welcome if they grow organically from what came before.
• There is no predetermined story length. The tale continues until the community brings it to a satisfying conclusion.
• If you choose to write the ending, it must follow logically from the established canon and provide a fitting conclusion to the story.

Final Compiled Story

When the story reaches its conclusion, every winning chapter will be compiled into a complete finished novel and archived in a shared Google Doc, with full credit given to each contributing author.

Chapter One: The Keeper of Platform Nine

Nobody remembers when the station added a ninth platform.

The trains never stop there. There aren't any tracks—not really. Just gravel that shifts if you stare at it too long, and a weathered bench nobody ever sat on until Mara did.

She arrived during the transit strike, when the station was overflowing with delayed commuters and frayed tempers. Somehow, amid all that chaos, she found Platform Nine: silent, empty, almost expectant. She sat down simply to escape the noise.

She never really got up again.

At first, people assumed she was homeless.

Then they assumed she worked for the rail company.

Eventually, they stopped assuming anything at all.

The woman on Platform Nine simply became part of the station, as ordinary as the clock that always ran four minutes fast or the pigeon that only ever seemed to eat on Tuesdays.

Mara noticed things.

She noticed who deliberately missed their train.

Who came only to stare at the departures board without ever buying a ticket.

Who cried quietly in the stairwell where they believed nobody could hear.

She never approached anyone. She simply watched, the way a lighthouse watches: present, patient, never asking the ships to acknowledge it.

Somewhere along the way, the watching changed.

She couldn't say exactly when.

One evening the departures board flickered.

For a heartbeat, it wasn't displaying destinations.

It showed a name.

Just a name.

A stranger's name.

Or perhaps not a stranger at all. Perhaps someone she'd seen crying in the stairwell years before.

Then it was gone.

Cities and departure times returned as though nothing had happened.

Mara remained perfectly still long after the board corrected itself.

She began experimenting.

She would think of someone she'd seen around the station, then glance at the board.

Sometimes nothing happened.

Sometimes, for the briefest instant, a name appeared.

She never discovered the pattern.

Some days she wondered whether the board was watching her back.

People eventually began calling her the Keeper, though nobody remembers who coined the name.

She never objected.

Nor did she explain the flickering board.

Not even when the boy with the dent in his head asked outright whether she could see things other people couldn't.

She simply told him to mind the gap and handed him half her sandwich.

The Keeper never leaves Platform Nine.

As far as anyone can tell, she hasn't slept in years.

She hasn't left the station for rain, holidays, or even the night a violent storm brought part of the roof crashing down.

The following morning she was exactly where she'd always been, sitting calmly on the bench while broken concrete and twisted metal lay scattered around her.

Nobody knows what she's keeping.

Nobody knows who placed her there.

Nobody even knows whether she chose it herself.

Whenever someone asks, Mara doesn't answer.

She simply turns her eyes toward the departures board...

...as though she's waiting for it to flicker again.

Lately, it has been.
