Presenting, the Complete Locked Tomb Timeline

Because I am a horrible nerd, I’ve compiled a complete timeline of every known event in the locked tomb trilogy so far. This is roughly divided into three parts:

Ancient History - this section is mostly based on the scraps of history we hear from the lyctors in HtN. The events are inferred from pieces or occasionally reconstructed by process of elimination.
Tragic Backstories - this section is based on what we learn about the backstories of the present day characters. The Cohort intelligence files in the GtN appendix were invaluable for getting the dates here.
Present Day - this section is a recounting of the events of the books put back in order and carefully placed on a timeline.

Please note that this contains SPOILERS FOR EVERYTHING including bonus content like The Mysterious Study of Dr. Sex.

The timeline itself is below the cut because otherwise this post would eat people’s dashes for breakfast.

Part One - Ancient History

10,001+ Years Before the Emperor’s Murder

Earth suffers from catastrophic climate change.
Many groups of humans abandon Earth and spread out across the stars.

10,001 Years Before the Emperor’s Murder

The world ends. A bomb is involved. 10 billion people die.
John Gaius is the only survivor.
John resurrects the people of earth, the planets of the nine houses, and the sun. He creates the nine resurrection beasts in the process and they scatter across the universe. The resurrections of the people are somewhat staggered and they don’t come back all at once.
The resurrected planets are thanergenic planets - that is, they continuously generate thanergy without dying. This makes them different from all other planets in the universe which are either thalergenic planets - living planets that continuously generate thalergy - or thanergy planets - dying planets that generate thanergy until they eventually die completely.
John meets Alecto. He calls her First, One and enters perfect lyctorship with her.
John renames the sun Dominicus to symbolize his divinity.
John cryopreserves many of the people he resurrected just in case he needs to recover from another catastrophe later.

10,001 - 9,000 Years Before the Emperor’s Murder

John begins to construct Canaan House as a palace from which to rule the new world.
Ten disciples gather at Canaan House. These are:

Augustine Quinque and Alfred Quinque
Mercymorn the First and Cristabel Oct
Gideon the First and Pyrrha Dve
Cassiopeia the First and Nigella Shodash
Ulysses the First and Titania Tetra

Half of the disciples become the first necromancers. The other half take up the sword and become the first cavaliers.
John uses his divine power to make his disciples immortal as long as they stay by his side.
The houses are founded. In recognition of their roles as founders, the disciples adopt their arithmonymics (number related surnames) :

Gideon and Pyrrha found the Cohort and the Second House on Mars.
The Third House is founded on Neptune without a disciple pair involved.
Ulysses and Titania found the Fourth House on Saturn.
Augustine and Alfred found the Fifth House on Jupiter.
Cassiopeia and Nigella found the Sixth House on Mercury.
The Seventh House is founded on Venus without a disciple pair involved.
Mercymorn and Cristabel found the Eighth House on Uranus.

Some of the children born in the new houses are necromancers. This effect cannot be replicated elsewhere in the universe because there are no other thanergenic planets.
Six second generation disciples who grew up in the new houses come to Canaan House. These are:

Cyrus the First and Valancy Trinit
Anastasia the First and Samael Novenary
Cytherea the First and Loveday Heptane

The disciples develop the secrets of interstellar travel by river and by stele.
Cristabel and Alfred formalize the cavalier oath.
Cassiopeia writes a large number of cookbooks.
Cyrus and Valancy create many nude oil paintings of each other.
Pyrrha and Gideon develop the mind melding transference theorem.
Mercymorn and Cristabel develop the siphoning avulsion theorem.
Cassiopeia and Nigella create Teacher and the other Canaan House constructs by cramming 500 souls into 50 vessels.
The disciples put their work together and create the lyctoral process. Cristabel convinces Alfred to commit suicide with her, forcing Augustine and Mercymorn to ascend.
Gideon ascends. He accidentally compartmentalizes Pyrrha in the process, preserving her as a second person trapped in his body.
Cassiopeia, Cyrus, Ulysses, and Cytherea achieve lyctorhood.
Cassiopeia and Anastasia work together developing a theory of perfect lyctorhood.
Anastasia attempts to obtain perfect lyctorhood. John sabotages her, killing Samael.
The lyctors beg John to kill Alecto. He agrees and they hold a funeral for her (funeral #1).
The lyctors stage their labs and studies so that someday more aspirants to lyctorhood may examine them. They each create trials based on their work.
Anastasia founds the Ninth House on Pluto. She’s ostensibly supposed to roll the rock on top of the tomb and be done with it but instead she creates an enduring cult.
Anastasia dies. The lyctors hold a funeral for her (funeral #2).

9,000 - 5,000 Years Before the Emperor’s Murder

The nine houses begin expanding an enormous empire across the stars. Lyctors set obelisks to expand the stele network and kill planets to make necromancy possible.
The lyctors realize that the resurrection beasts have come to hunt them. They permanently leave the nine houses and begin living aboard the Mithraeum, a space station in imperial controlled space.
Cyrus moves his nude oil paintings and all of Valancy’s clothes from Canaan House to the Mithraeum.
Cassiopeia moves her cookbooks and her ceramics collection from Canaan House to the Mithraeum.
All seven lyctors fight and kill Number Two together.
Cyrus dies drawing Number Six into a black hole. The lyctors hold a funeral for him (funeral #3).
The remaining six lyctors move the Mithraeum to deep space and flee there.
The lyctors try Gideon and Ulysses’ spearfishing idea to fight Number Eight. It goes badly and Ulysses dies wrestling the beast into hell. They hold a funeral for him (funeral #4).
Two more resurrection beasts are killed. These are Number One and Number Four.

~5,000 Years Before the Emperor’s Murder

The expanding empire encounters Blood of Eden who has been searching for them this whole time.
BOE begins shepherding an insurgent movement to fight back against the nine houses.

5,000 - 1,000 Years Before the Emperor’s Murder

The evolving cultural concept of necromancer and cavalier begins to lead some necromantic aristocrats to choose cavaliers for their political value, not their skill at swordplay. This will be an ongoing debate for the next 5000 years.
The Master Warden of the Sixth sets the rules for the Swordsman’s Spire to prioritize genetic outreach potential first and competency second. These will stand unchanged for half a myriad until Palamedes interferes with them during his time in the position.
Cassiopeia explains how to use a relative’s blood to trick blood wards to Mercymorn.
Cytherea attempts to physically plant a bomb on a resurrection beast. She goes mad before she can even reach the surface and has to spend weeks recovering.
Cassiopeia attempts to draw Number Seven into the river physically. She is torn apart by angry ghosts and fails to harm it. The lyctors hold a funeral for her (funeral #5).
