Allomancers are individuals in the fictional universe of Mistborn, created by author Brandon Sanderson. They possess the unique ability to ingest and "burn" specific metals, granting them various powers. Each metal corresponds to a different ability, such as enhanced strength or the power to manipulate emotions. In this world, Allomancers are categorized into two main groups: Mistings, who can use only one metal, and Mistborn, who can utilize all known metals. This system of magic plays a crucial role in the story's plot, influencing the characters' abilities and the dynamics of power within the society.
