Pits of Hathsin

Fictional record. This page describes a mine from a fictional setting, not a real place. Information is based on the cited canon, with adaptations and interpretation distinguished where necessary. It is kept separate from the real MineArchive corpus — see Fictional.

Also known as	Hathsin, The Survivor's Cradle
Setting	Mistborn (Brandon Sanderson)
Location	A system of caves and crevasses in the Central Dominance of the Final Empire on Scadrial, near the capital Luthadel; Kelsier looks north from a Luthadel rooftop towards them.
Type	Metal
Worked	Worked under the Lord Ruler throughout the thousand years of the Final Empire; Sanderson has said Preservation shaped the place to hide the fragment of Ruin's power that grows there as atium. – Wrecked by Kelsier days before the Collapse, ending atium production for an estimated three hundred years; no atium grows there after the Final Ascension.
Extent	The only known source of atium in the Final Empire: narrow gorges whose crystal-lined niches yield one geode a week from each prisoner, on pain of death.
Controlled by	The Lord Ruler (Throughout the Final Empire, to the Collapse)

Overview

The Pits of Hathsin are the atium mines of Mistborn: The Final Empire, disguised as a death camp for skaa criminals. Prisoners are made to climb down suffocatingly narrow gorges and reach into crystal-lined niches for the geodes that hold atium, the Lord Ruler's rarest metal, and any who fail to find one in a week are beaten to death. Kelsier, sent there with his wife Mare for trying to rob the Lord Ruler's palace, is the first known survivor; Mare dies, he Snaps into his Mistborn powers and escapes, and the title 'Survivor of Hathsin' follows him. On the eve of the Final Empire's fall he returns, frees the prisoners and shatters the atium crystals, reckoning that nothing more will be mined there for three hundred years. This record is written from a fan wiki and the author's annotations, not from the novels themselves.

History

Within the Final Empire the Pits are known only as the Lord Ruler's deadliest labour camp; that they are his atium mine is a secret the camp's purpose serves, since no prisoner leaves. Kelsier and Mare are sent there after attempting to rob Kredik Shaw, the Lord Ruler's palace, and it is there, after Mare's death, that Kelsier Snaps and becomes Mistborn, escaping and taking the name the Survivor of Hathsin. The first novel's crew learns the Pits' secret in the course of its plan against the Lord Ruler, and Sanderson's annotation to the chapter in which the crew shelters in caves records that he had not originally meant those caves to be the Pits: the cracks in the ground 'clicked' with what he had planned for them, and let him explore Kelsier's past. Several days before the Collapse Kelsier returns, frees the enslaved skaa and, burning iron to sense the traces of atium in the crystals, Pulls on them so that they shatter; he remarks that his actions will likely end atium production for the next three hundred years while the crystals regrow. After the Collapse the Pits become the home of the Terris people, who turn the old camp's shelters, water and ash-hardy crops into pastoral villages, and the place comes to be called the Survivor's Cradle. After the Final Ascension that ends the trilogy no atium forms in the crystals, and by the time of the later Wax and Wayne novels it has not regrown; asked in 2012 whether the Pits survive Sazed's remaking of the world, Sanderson answered 'RAFO', and told another questioner that the conspirators of The Alloy of Law were 'on the right track'.

Workings

Not a mine in any engineered sense: a natural system of crevasses and caves whose walls are lined with crystals in which atium geodes grow. The prisoners' work is to climb down the narrowest cracks, reach into the crystal niches and prise out the geodes by hand, each owing one a week; the geodes are broken open for the beads of atium inside. There are no tools, no timbering and no shafts, and the camp above is a prison rather than a colliery village.

Closure

Kelsier's destruction of the atium crystals on the eve of the Collapse, and the cessation of atium's formation after the Final Ascension.

What became of it

A Terris pastoral settlement, the Survivor's Cradle, on the site of the camp; no atium has grown since the Final Ascension.

Canon & adaptations

None between tellings; the Coppermind's later material on the Pits' cosmological nature (a Perpendicularity of Ruin, used by worldhoppers for trade) comes from Sanderson's later books and Q&A rather than from The Final Empire itself, and is recorded here as fan interpretation.

Recorded claims

Each claim is marked with its basis — explicit canon, MineArchive inference, adaptation only, or fandom interpretation — and attached to the source(s) below. Where tellings disagree, both are kept.

The Pits are a system of caves near Luthadel in which atium geodes grow, known to the Empire only as a deadly skaa labour camp; they were the only known place where atium could be mined. (fandom interpretation) ¹
Prisoners climb down a suffocatingly narrow gorge and reach into crystal-lined niches for the geodes; each must find one a week or be beaten to death. (fandom interpretation) ¹
Kelsier and his wife Mare were sent to the Pits for trying to rob Kredik Shaw; Mare died, Kelsier Snapped and escaped as a Mistborn, the first known survivor, and was called the Survivor of Hathsin. (fandom interpretation) ^1,2
Days before the Collapse Kelsier freed the prisoners and shattered the atium crystals by Pulling on them with iron, remarking that atium production would likely end for three hundred years. (fandom interpretation) ¹
Sanderson wrote in his 2006 chapter annotation that he had not planned the crew's caves as the Pits, but the cracks in the ground 'clicked' with what he had planned for them and let him explore Kelsier's past. (MineArchive inference) ³
The Pits became the home of the Terris people, who turned the camp into pastoral villages, and were later called the Survivor's Cradle; no atium grows there after the Final Ascension. (fandom interpretation) ¹
Asked in 2012 whether the Pits still exist after Sazed reshaped the world, Sanderson answered 'RAFO'; he told another questioner that the timeline of The Alloy of Law's conspirators was 'on the right track'. (MineArchive inference) ³
The Coppermind records the Pits as the site of a Perpendicularity of Ruin and as a place Preservation made to hide a stolen fragment of Ruin's power, drawing on later books and Q&A rather than The Final Empire. (fandom interpretation, uncertain) ^1,3
