The Locked Tomb fanfiction generator
A Locked Tomb fanfiction generator writes the Nine Houses — necromancers and cavaliers, ten thousand years of empire, and bone everywhere.
The Locked Tomb's central relationship — a necromancer and the cavalier sworn to them — is one of the most intense bonds in modern fiction: lifelong, service-based, and built on a devotion neither party will admit to. SecretPen writes the cavalier bond, which is a ready-made D/s dynamic with a ten-thousand-year religion behind it.

Three openings to steal
Click one and it lands in the desk, already typed. Change any word you like — it's a starting line, not a script.
Sworn
I have been sworn to her since I was old enough to hold a sword, which is a religious obligation and a legal one, and tonight she asks me whether it is only those things.

Bone
She can build anything out of it, including a version of a body, and tonight she demonstrates something that I am going to be thinking about for the rest of my life.

Ten thousand years
The Lyctor across the table remembers the empire being founded and has watched everyone she loved die four separate times, and she is being extremely light about it.

What makes The Locked Tomb land
- The necromancer-cavalier bond is service, devotion and lifelong obligation.
- Everyone here is unwell and extremely funny about it. Keep the humour.
- Death and resurrection are ordinary, which changes what a body means.
How far it goes
The Nine Houses and the Emperor's empire, necromancers and cavaliers, Canaan House and the Ninth, the Lyctors and the River, and the wider series. Ships across Gideon and Harrow, Lyctor pairings, rare pairs and x-reader as a cavalier or an adept. Tropes including sworn service, devotion without declaration, body horror and resurrection, and gallows humour throughout. 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.
Start writing →Questions
- Does it keep the humour?
- Yes — the tonal mix of gallows humour and genuine horror is what makes this series distinctive, and losing either half loses the book.
- Is the cavalier bond a D/s dynamic?
- It reads as one, and SecretPen writes it that way — lifelong sworn service with devotion neither party will name is exactly that.
- 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.
