档案中的回响：隐藏门运行中

Seventeen missed calls. A snapped security lanyard. An academic researcher, vanished into thin air…and it turns out, she’s not the first to go missing.

Let's back up.

Hi, welcome to Hidden Door, your favorite narrative worldbuilding platform. Today we're going to explore a scary story, turn-by-turn, in The Call of Cthulhu. I’m your friendly guide, Hattie Hayes, here to demonstrate what to expect during your first-ever Hidden Door story!

This is a real story, that I actually played, from character creation to the dramatic twist. And the timing couldn't be better for a creepy, occult world like this one: October is when Halloween happens. Halloween is scary. And what could be scarier than working in academia a cult serving an eldritch monster?!

We’re going to play the original recipe, no modifier cards, because we’re aiming for PSYCHOLOGICAL THRILLS. First, I’ll build my character. I just finished re-watching 30 Rock, so we’ll name my character Kenneth, and I just started watching Supernatural, so for character high concept, let’s select…ooh, “demonologist with academic credentials.”

I save the background questions for last, because they’re my favorite part! Here’s how I answered this time around:

-What’s a quirky interest this character has? Playing in an all-ukulele band

-What’s a scary memory from childhood? Their dad was tied to the train tracks by a business rival

Here’s the completed character profile:

Looking great, Kenneth! Time for you to suffer!

I get to choose between three origin stories: The Brass Relic, Echoes in the Archive and The Inked Map. As much as I looooove cursed objects, the archive-investigation story promises a handwritten note AND mysterious warnings from a dead colleague, so that’s where we’re headed!

My first scene starts by introducing our setting and cast. Kenneth’s friend Nadia, a part-time research aide, is working the front desk at one of the many libraries in Miskatonic University. Like any good friend would, Kenneth is visiting her at work, distracting her from her job!

Ok, not entirely: Kenneth is helping Nadia put away the day’s returned books, including a big box of old books which was apparently dropped off when no one was looking. Nadia tells me and Kenneth it’s the arcane Crowley collection, all returned three weeks late, and…with a weird, old notebook mixed in. It’s definitely not a library book.

At first, Nadia is sure that it belongs to Kenneth, but on my turn, I quickly decide that Kenneth will deny any knowledge of the faded volume. The game engine will remember this decision I make. Just as Nadia picks it up to start investigating, something even weirder happens: a delivery driver charges through the doors with a huge crate, sent by someone named Elias Marlowe, and intended for…Kenneth? MY Kenneth???

Nadia wastes no time in prying the box open before Kenneth & I can investigate for ourselves. The lid of the crate comes off in a huge plume of dust motes, and piled inside are…more notebooks. There are field journals, there are maps and a compass, too, but the freakiest thing is a notebook that looks exactly like the one Kenneth and Nadia found in the library, moments before the package was delivered.

Touching the compass sparks a faint memory for Kenneth, something from 15 or 20 summers ago. Hmm. That might be connected to the tragic backstory I hinted at during character creation (after all, death is VERY real in this world). I take note of that, then Kenneth starts actually reading the notebooks:

The margins swarm with cramped notation: "Leng symbols match Carstairs, not Waite." "The angles are wrong for terrestrial geometry."

The handwriting is not yours. But the question is.

Oh...kay. I have unlimited options here, and all of the suggestions look good — that flash of repressed memory is interesting — but I’m going to take this opportunity for a one-on-one chat with Nadia. I open a chat window and ask Nadia for her thoughts. She has a couple of theories, but she’s in the dark on the “Elias Marlowe” guy, and whether he sent us this package:

A colleague or a former student, both sound plausible. Or he could be someone who has it out for Kenneth! I’m eager to get to the archive and solve this mystery, so I volunteer Kenneth and Nadia to race to the archives, and ooh! It triggers a minigame! Kenneth successfully beats Nadia in the race, even though she insists it was a tie (sore loser!). If I’d lost the minigame, I would’ve actually lost in the story, too. The minigames’ outcomes have stakes!

Now, we enter the archive. Nadia says, “Welcome to the rest of your life, I guess,” which is a little ominous.

This next turn has a lot of story details. The leather of the notebooks “seems to drink the light.” Everything in the archive is physical media, not digital. I can nearly smell the old-book aroma. And one of the cards in the catalog tells me where to find Marlowe’s work: in the Restricted Holdings section, which Kenneth can’t access without written permission from the Dean.

While Nadia does some research on her phone (seems like she’s calling in a favor), Kenneth and I take a closer look at the notebooks. The first notebook ends somewhat abruptly, in writing that’s mostly discombobulated. But in the final entry, Kenneth notices a significant detail:

The handwriting deteriorates across the page, the letters losing their upright discipline, slanting toward something that resembles no alphabet you know.

But between the lines, in pencil so faint it's nearly vanished, someone—Marlowe, you think, or someone who held this after him—has written coordinates. A date: three weeks from now. And beneath it, in English, in shaking script: "He believed they were waiting. I believe they are patient."

The silence has the particular gravity of rooms where something has been waiting a very long time for someone to finally look.

This moves us into our next scene. Nadia is still making her secret phone call, and I’m not 100% sure what Kenneth’s next action should be. So, I ask the Narrator! This is a neat trick when you’re in the middle of a story and you need more guidance, want to change the pace a little, etc etc.

In this instance, I try to see if the Narrator will tell me who Nadia’s calling.

But, nope, the Narrator won’t reveal any secrets before they’re unveiled in the narrative. Fair enough! Instead, I ask, “What should I do while Nadia is busy?”

The Narrator’s advice is to start looking into those coordinates mentioned in the journal, and that a map in the archive might hint at what’s waiting for Kenneth.

As Kenneth pulls out a map, Nadia’s friend and colleague Kian joins us. Yes!!! Kian works in the archive and is going to try and help Kenneth and Nadia get access to Restricted Holdings. We’re still waiting on her, but reinvigorated by Kian, I decide that Kenneth should find more clues. Looking through the archive, he finds an important-looking folder, holding a weird clue: a single receipt, dated two weeks ago, and signed for by someone whose name has been scratched out with a knife.

This is huge. But where is Nadia??? Kenneth asks Kian, who is surprised that we don’t know. Wasn’t she just with us? The narrative world model and story engine are able to create this sort of tension, because there is an answer to the question “where is Nadia?" It's just that neither myself nor any of the other characters have learned it yet.

I decide it’s time to call her.

The line connects on the third ring — too long, each pulse a small wound — and then her voice, breathless, background noise crashing through: "Ken, I can't talk, I'm—"

A door slams on her end. The line goes dead.

AHHHHHH! Okay, it’s officially time to get the hell out of here! I have seen three and a half seasons of American Horror Story, I know the rules!

But Kenneth (good friend) will not leave Nadia behind. I know the Narrator can’t rescue her for me, but I ask for a little help:

“I'll give you a concrete clue to Nadia's location in the next turn, keeping the search front‑and‑center,” the Narrator reassures me. And when I go back to the story, I get that reassurance right away:

Sure enough, on the next turn, Kian and I discovered a crumpled campus map with a handwritten note for Nadia in the margin: Reception Hall to Archive Transfer, escort required. Route B, sub-basement access.

A sub-basement?! A basement BELOW the basement??? Kenneth, you’re gonna die! Today!

Kenneth and Kian start moving toward the basement stairs, and as they do, heavy footsteps start up behind them.

I decide to ask Kian if he knows anything about Marlowe. If he works in the archives, maybe he’s heard the name!

Good news: Kian does know who Marlowe is!

Bad news:

“After Marlowe read that notebook alone, the campus caretaker found him in the stacks. He'd—" Kian stops. His eyes fix on something past your shoulder, up the stairs you just descended. "He'd clawed his own eyes out. And he was smiling."

The game helpfully updates Kenneth’s status: You are now terrified.

I want to GET NADIA and LEAVE IMMEDIATELY, but the Narrator knows that’s a multi-step process and helpfully breaks it down to the first action:

Ok! Just look for Nadia on our way out of the basement. That’s doable.

We finally get through the sub-basement route to the desk where Nadia was supposed to be. She’s not there. But her phone is, the case cracked, a lock screen showing seventeen missed calls from a number none of us recognizes. And beside it is a security lanyard, snapped clean through.

Someone was here with her. An outsider. They’re both gone now, and we don’t know where.

Aaaand that’s where the scene ends. I’m on the edge of my seat, but don’t worry, there’s plenty of room for you here!

I’ve heard a rumor that someone heard Nadia deep in the library’s restricted holdings section, talking to herself and laughing hysterically. Kenneth and I need to go investigate. And I think you're ready to start exploring Miskatonic University on your own.
