Allomancy

Allomancy is a form of magic existent on Scadrial, originated from the Shard Preservation.

Those capable of using Allomancy can injest an Allomantic Metal and burn it inside their body, bringing about different effects depending on the metal burned.

Most users fall into the catagory known as Mistings, where they are only capable of using a singular type of metal, but a rare few are Mistborn, capable of using all Allomantic Metals.

Metal Classification
Metals are classifed in pairs, a base metal which possesses a Pulling Attribute, and an alloy of said metal which possesses a Pushing Attribute.

These are further subdivided into Internal/External Metals, depending on if they have an effect upon the outside world, or upon the Allomancer themselves.

This is seperated into Mental/Physical/Temporal/Enhancement Metals, depending upon what they effect. With each group containing four metals.

Outside of these are three God Metals, which do not fit squarely into any of the sixteen catagories. And are far rarer, due to being the metallic form of Shards.

Tin (Internal Physical Pulling Metal)
Tin is a metal that, when burned, greatly enhances all of the senses of a Allomancer. Tin Mistings are known as Tineyes.

Pewter (Internal Physical Pushing Metal)
Pewter is a metal that, when burned, greatly enhances the physical strength of a Allomancer. Pewter Mistings are known as Pewterarms or Thugs.
