Atium

Fictional record. This page describes a mining commodity from a fictional setting, not a real material. 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.

Atium is the rarest and most valuable metal of the Final Empire in Brandon Sanderson's Mistborn books: a silvery, intensely reflective metal found as beads inside geodes that grow in the crystal-lined crevasses of the Pits of Hathsin. It is not an ordinary mineral. Atium is a God Metal, the condensed power of the Shard Ruin, and an Allomancer who burns a bead of it can see a few seconds into the future.

Where it occurs

One source only, in the whole of Scadrial: the Pits of Hathsin in the Central Dominance, where the geodes grow in niches in the crystal that lines the gorges. Because atium is a God Metal it does not form by any natural process; Sanderson has said that Preservation shaped the place so that the fragment of Ruin's power trapped there would seep out as atium. That single source is the whole of the metal's geography, and it is why the Lord Ruler held the Pits as a secret and worked them with prisoners who never left.

How it's obtained

Not mining in any engineered sense. Prisoners climbed down the narrowest crevasses, reached into the crystal niches by hand and prised out a geode, which was then broken open for the beads inside. There were no tools, no timbering and no shafts, and each prisoner owed one geode a week on pain of being beaten to death. Kelsier's destruction of the crystals on the eve of the Collapse ended production, and the sources give about three hundred years before any atium would have grown again — in the event, none grows after the Final Ascension.

Properties

A reflective silvery metal, so bright that beads of it are described as looking almost like drops of liquid. Burned by an Allomancer it throws off atium shadows of everything in sight, showing their movements a few seconds ahead and expanding the burner's mind enough to process what it sees, so that even an attack from behind can be dodged. Two people burning atium at once cancel much of the advantage, each shadow splitting into possibilities as both try to predict a future the other has just changed. A Feruchemist can store youth in it, and as a Hemalurgic spike it steals any power. Its only established alloy is malatium, atium with gold.

Why it's valuable

Atium was the economic and military foundation of the Lord Ruler's thousand-year rule. He held the only source, kept its location secret behind a labour camp, and controlled the supply absolutely; an Allomancer with atium could out-fight almost anyone without it. Destroying the source was therefore an act of war on the regime rather than simple sabotage, which is what makes the Pits of Hathsin a mine that matters to its story rather than scenery.

Uses

Burned by Mistborn and by the Mistings called Seers for its few seconds of foresight; stored by Feruchemists as youth; used in Hemalurgy to steal any power. Alloyed with gold as malatium it gives a different temporal effect again. Beads of it also served as currency and as the Lord Ruler's instrument of patronage among the nobility.

Canon & adaptations

The first novel presents atium as the pure God Metal of Ruin. Later books in the series revise this: atium is an alloy of electrum with that pure metal, and can be refined to extract it. Sanderson has also said he wishes he had made atium burnable by every Allomancer rather than by Seers alone, and that he modelled it on platinum, treating it as a platinum-group metal. Readers of The Final Empire alone will not meet the refinement or the electrum alloying at all.

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.

• Atium is a God Metal, the condensed power of the Shard Ruin, and so does not form by natural process. It appears as a reflective silvery metal whose beads are described as looking almost like drops of liquid. (fandom interpretation)
• The Pits of Hathsin are the only source of atium in the Final Empire, the geodes growing in crystal-lined niches in the gorges. Sanderson has said Preservation shaped the place so that the fragment of Ruin's power held there would seep out as atium. (MineArchive inference)
• An Allomancer burning atium sees a few seconds into the future, atium shadows showing the coming movements of everything in sight and the burner's mind expanding enough to act on them. Two atium burners facing each other lose most of the advantage, the shadows splitting into possibilities as each changes the future the other predicted. (fandom interpretation)
• A Feruchemist can store youth in atium, and as a Hemalurgic spike it steals any power. Its only established alloy is malatium, atium with gold. (fandom interpretation)
• The first novel treats atium as Ruin's pure God Metal. Later books establish that it is an alloy of electrum with that pure metal and can be refined to extract it. (fandom interpretation, disputed)
• Sanderson has said atium was modelled after platinum and would be considered a platinum-group metal. (MineArchive inference)

Fictional mines producing this

Included only where MineArchive's own research gives a reasonable evidential basis.

• Pits of Hathsin
  The Pits of Hathsin are the only source of atium in the Final Empire, and the geodes the prisoners prise from the crystal are the whole of the metal's production.
