TMA's horror is bureaucratic and personal at once: a workplace where the paperwork is eldritch and everyone is slowly becoming something. Its fic is unusually tender against that background, which is the whole appeal. SecretPen keeps the dread running underneath the warmth.

What makes The Magnus Archives land

How far it goes

The Magnus Institute and the Archives, the fourteen entities and their avatars, statements and their effects, the tunnels, and post-canon settings. Ships across Jonmartin, rare pairs and x-reader as an assistant or a statement-giver. Tropes including workplace horror, slow transformation into an avatar, hurt/comfort with genuine damage, and domesticity under apocalyptic conditions. Every character is an adult.

How it works

01

Say it in one line

One sentence is enough. Who's in the room, and what has already been decided between them.

02

Set the dial

Tone, heat, point of view, length. Or skip it — the defaults are tuned for people who'd rather just read.

03

Keep going

Chapter one arrives in seconds. Steer the next one, change your mind, or let it run.

Nobody else reads this.

SecretPen has no public feed, no community rankings, and no way for one reader to see another's stories. Whatever you write here stays in your account — that's the whole point of the name.

Questions

Can the horror stay present?
Yes — ask for it. The dread and the domesticity running at once is what makes this fandom's fic distinctive.
Does it use the entities correctly?
Yes. Name which fear is involved and it shapes the horror specifically rather than generically.
Is any of this public?
No. SecretPen has no public feed, no community rankings and no sharing — there is no mechanism by which one reader can see another reader's stories. Everything you write stays in your account.
How explicit does it get?
As explicit as you ask for. There is no fade to black and no lecture. The only limits are the hard lines in our content guidelines: everyone is an adult, nobody real, nothing illegal.
Do I have to pay to try it?
No. You can write your first story free. Paid plans exist for people who write a lot of them.
