Feruchemical Metalminds
Magic SystemSmall metal items like thick iron bracers on upper arms, copper bracers, earrings, rings, bracelets; plain metal bands or simple shapes; worn as cultural jewelry by Terrismen; store physical attributes like strength, memories, sight without burning.
Feruchemical metalminds begin as visible cultural jewelry in The Final Empire—simple iron and copper bracers, rings, and earrings worn openly by Terrismen to store physical and cognitive attributes. By The Well of Ascension they have become sophisticated, body-hugging devices capable of dramatic physiological transformation, their forms expanding from thin rings to heavy, segmented bracers that can magnify strength or weight without distorting skin. In The Lost Metal the technology shifts again: metalminds are now surgically embedded beneath the skin, transforming from ornamental objects into concealed implants that preserve secrecy while retaining full Feruchemical function.

Expandable metal braces/rings/bracelets/bracers/piercings (e.g., unconnected on one side for pewter/iron, thin heavy iron/pewter ankle bracelets, small tin/copper finger rings, large coppermind arm bracers) worn on body; store physical/mental attributes like strength (bulging muscles), weight (crushing heaviness), warmth (body heat), senses, speed; body transforms dramatically without loose skin; filled by Feruchemists then tapped for power
