Elemancy is Metal Shadow's iteration of magic. It is the science of controlling the elements. Those who practice elemancy are called elemancers.

In Metal Shadow Prelude, the term was never explicitly used. However, something called ether was identified as a component in elemancy for emblazon formation. The four ethers are: sol, chak, vessa, and verra.

In the prologue of the main canon, eight elements were identified: fire, water, earth, wind, lightning, ice, ore, and wood.

Elemancy is apparently foreign to most people in Gilta Nnea, since the arrival of the Elemancing Guild and the Red Threat's use of elemancy were the first instances many ever saw it.
