Summary
More then a thousand years before the sorrow of Harrowhark Nonagesimus: before the call for new Lyctors, before the razing of Canaan House, before the opening of the Locked Tomb...
A solider of the Ninth returns from the Front with a red headed babe cradled in his arms. A solar wind blows across the planet's icy surface. Not the beginning. But a beginning.
The Dragon rides again on the winds of time.
Or,
Rand al'Thor might not have a Niner name, but he wishes for nothing more then to honor and serve his House, protect it from danger and elevate it's glory.
And then a boy with a sly fox like smile falls into his life and changes everything.

03 Aug 2025
Tags
Summary
Silas watches intently from his seat at the table as Colum scatters some mushrooms and peppers into the pan and then carefully folds the egg over itself, enclosing them inside. There is a book open in front of him, ignored but for the way his fingers worry at the corner of the page.
“Would you like me to teach you?”
His necromancer scoffs, eyes returning to his book abruptly. “What use have I for cooking? That’s the cavalier’s domain. Would you prefer to be uselessly redundant?”
Colum offers to teach Silas to cook.

Summary
Gideon Nav is not a necromancer, even if she can technically raise a couple of skeletons. When Harrowhark sabotages her shuttle and forces her to pretend to be her cavalier, all Gideon wants is the chance to get off-planet. Between a vow of silence, secret notes between the original Lyctors, and something on the First hunting them down one by one, Gideon barely has the time to worry about hiding her necromantic aptitude.

Summary
In a world of constant noise and color, nothing made sense to Ken Takakura, a young necromancer of the Sixth with an extraordinary (but uncontrollable) talent.
Until he met Momo Ayase, a commoner from the Fifth House with a damn good sword arm and the most cosmic pink eyes he'd ever seen.
This is a story of how she found him, the promises that would be made, and how he broke them.

Look Me in the Eye by MortonMurphy
Fandoms: The Locked Tomb Series | Gideon the Ninth Series - Tamsyn Muir
02 May 2025
Tags
Summary
You think about my last moments, from time to time. You think of the gasp that left my throat, of the wideness of the eyes that now rest in your sockets. You hear Corona’s screams, while tasting the tang of my blood in your mouth as you forced my soul down your throat–all while trying to drown out Corona’s sobs.
Is THIS why you can’t look at Augustine the First at all, as he drowns? Is this why you instead focus on shooting the breeze with the Necrolord Prime–as if your big brother lyctor isn't dying because of you at this very instant?
After dooming him, you can’t even do him the honor of looking him in the eyes.
...honestly, this is so on brand for you, Ianthe.
OR, Ianthe makes a decision on who to save, and the guy whose soul she ate judges her about it.

Death First to Vultures and Scavengers by Roguelike
Fandoms: Arcane: League of Legends (Cartoon 2021), The Locked Tomb Series | Gideon the Ninth Series - Tamsyn Muir
05 Apr 2025
Tags
Summary
Across the Nine Houses, a summons is sent. More Lyctors are needed. For many necromancers, like Ambessa, Mel, and Silco, this is an opportunity for power. For others, like Jinx, a chance at redemption, reclamation. For Viktor and Dr. Reveck, a chance at life itself. No matter what, glory awaits the chosen few, their cavaliers by their side.
Or so everyone thinks. The reality is a lot less glamorous. Shifting allegiances, old enemies reunited, and the biggest shock of all: what it really costs to achieve Lyctorhood.
Do you like TLT? Do you like Arcane? Do you like angst? Do you like ridiculous plotlines and bizarre crossovers? Boy do I have the fic for you.

Side Piece by MortonMurphy
Fandoms: The Locked Tomb Series | Gideon the Ninth Series - Tamsyn Muir
04 Apr 2025
Tags
Summary
Harrowhark didn’t want her name in lights. She didn’t want to step alongside you, further into lyctorhood, into glory. She didn’t want to share the experience, to look upon you with the eyes of her cavalier and see someone as great as her. Someone else who’d been able to ascend, to grace the presence of the Emperor Undying. She’d rather fall apart at the seams for her supposed meat shield than acknowledge you.
Side. Piece.
Not even that. You’re an uneasy ally, your lobotomy was essentially a booty call, a desperate plea to preserve the one she actually gives a rat’s ass about. You have to know that you’re below a dead meathead on the Harrowhark priority rankings.
Ouch.
Maybe that’s why you elect, after a period of awkward silence, to leave her in a pile of tepid water and her own blood, wheezing softly.
OR, Ianthe comes upon Harrowhark at the end of Ch. 24 of HtN, in the aftermath of the Saint of Duty's bath-ambush.

The Locked Souls by camylljoy

Summary
“Open your eyes, Griddle. We’ve got to run. They’ll be coming for us.”
Red (AKA Gideon) wakes up from an amnesia-inducing concussion nap. She's only got a sentient sword and a dead body for company, and Drearburh's entire zombie army on her ass. Oh, and someone stole her voice. She needs that! So obviously, Gideon's next step is to take the sword (which is very snarky and rude, as it turns out) and fight her way to the Castle. Gore, sarcasm, and more than a few plot twists ensue.
The Locked Tomb/Transistor/Dark Souls AU that no one asked for.
