World of Origin	Scadrial

Feruchemy is one of the three prime manifestations of Investiture on Scadrial. The natives of that world consider it one of the three Metallic Arts.

Lore & Background

Feruchemy is the only of the Metallic Arts that existed long before the Lord Ruler's Ascension. It is a genetic ability found in the ancient people of Terris, but now that most Terrismen are eunuchs because of the Lord Ruler's breeding programs, Feruchemists are now exceedingly rare.

A Feruchemist can use metals to store particular attributes in metal, somewhat like a battery. The larger the piece of metal is (and the closer it is to Allomantic purity), the more of that particular attribute can be stored. A Feruchemist can draw upon their metals in increased, compounded qualities, but the faster they do this, the lesser returns they receive. Only the Feruchemist who stored those attributes can draw upon them later, however.

Like Mistborn and Mistings, there are Feruchemists that can utilize one or all of the metals. The former are known as "Ferrings"

Terminology

A metalmind is what Feruchemists' call a piece of metal where they can store human attributes in. Each metalmind is named after the type of metal it is, for example: ironmind, pewtermind, coppermind, goldmind.

When a Feruchemist places something in the metal, it is known as storing. A Feruchemist's power comes from his or her own body, so if a Feruchemist was storing strength, that Feruchemist would must remain weak during that time. When a Feruchemist draws upon his or her metalminds, it is called tapping.

Feruchemic Metals

Feruchemical Properties of Metals

Physical

Iron

Iron stores Physical Weight. Storing weight does not store actual mass in your body--that remains the same. When a Feruchemist stores weight, they store the way gravity affects their body. Storing iron, then, can be used to lighten yourself, which can makes falls less harmful.

An iron Ferring is known as a Skimmer.

Steel

Steel stores Physical Speed. Tapping steel will allow the Feruchemist to move at amazing rates, while storing it will cause the Feruchemist to move more slowly.

A steel Ferring is known as a Steelrunner.

Tin

Tin stores Senses. Tapping a tinmind gives the Feruchemist enhanced sensory perception. However, this will not allow the Feruchemist to see in the dark; rather, it enhances what eyesight/senses are already there. In addition, tapping tin will not make the mists more translucent, as an Allomancer burning tin would

A tin Ferring is known as a Windwhisper.

Pewter

Pewter stores Physical Strength. Tapping a pewtermind will cause a Feruchemist's muscles to grow far larger than they would be normally, while storing Strength causes the Feruchemist to become weak and frail.

A pewter Ferring is known as a Brute.

Cognitive

Zinc

Zinc stores Mental Speed. Tapping a zincmind will give the Feruchemist the ability to think much faster than a normal person, while the thoughts of a Feruchemist storing this quality will be thick and sluggish.

A zinc Ferring is known as a Sparker.

Brass

Brass stores Warmth. Tapping brass will make the Feruchemist feel warmer.

A brass Ferring is known as a Firesoul.

Copper

Copper stores Memories. When storing memories, the Feruchemist loses all recollection of that information he or she stored. Typically, Keepers (modern-day Feruchemists) would have many copperminds, keeping specific index copperminds to locate particular pieces of information.

A copper Ferring is known as an Archivist.

Bronze

Bronze stores Wakefulness. Tapping bronze will enable the Feruchemist to stay awake longer.

A bronze Ferring is known as a Sentry.

Spiritual

Duralumin

Duralumin stores spiritual connection. Reducing other people's awareness and friendship with them during active storage. Tapping it can help speedily forming trust relationships with others.

A duralumin Ferring is known as a Connector.

Aluminum

Aluminum stores a spiritual sense of identity. This is an art rarely spoken of outside of Terris communities, and even among them it is not yet well understood.

An aluminum Ferring is known as a Trueself.

Chromium

Chromium metalminds allow the user to store fortune. Making themselves unlucky during active storage, and tapping it at later times to increase their luck.

A chromium Ferring is known as a Spinner.

Nicrosil

Nicrosil allows one to store investiture. This is a power that very few know anything about, and the people of Terris don't truly know what they are doing when they use this power.

A nicrosil Ferring is known as a Soulbearer.

Hybrid

Gold

Gold stores Health. Tapping a goldmind will rapidly heal wounds, but the expense of gold, combined with the difficulty of storing health, means that most Feruchemists do not have massive goldminds to tap from.

A gold Ferring is known as a Bloodmaker.

Electrum

Electrum stores determination. Storing determination makes people enter a depressed state during active storage, and while tapping it later can make them enter a determined, manic state.

An electrum Ferring is known as a Pinnacle.

Bendalloy

Bendalloy can store nutrition and calories. Users can eat large amounts of food during active storage without feeling full or gaining weight, and then can go without the need to eat while tapping their metalmind. A separate bendalloy metalmind is used for fluids intake.

A bendalloy Ferring is known as a Subsumer.

Cadmium

A Cadmium metalmind can store breath. During active storage they must hyperventilate in order for their bodies to get enough air. The breath can be retrieved at a later time, eliminating or reducing the need to breathe using the lungs while tapping the metalmind. They can also highly oxygenate their blood.

A cadmium Ferring is known as a Gasper.

God Metals

Atium

Atium stores Age. Storing age is usually a fairly useless endeavor: in order to be young for a time, a Feruchemist needs to stay older for a time. It can, however, be useful for disguising a Feruchemist's identity.

The name for an atium Ferring is, as of yet, unknown; as none have been discovered to the knowledge of the world at large.
