Mutants are Homunculi infected by toxic emissions beneath the Land of Fumes and transformed into uncontrollable, wild beings.
History
Mutants were once sapient Homunculi meant to assist humans and harvest the mystical resources of the Land of Fumes. When the latter failed, toxic fumes emerged, driving them insane. As a result, the Homunculi devolved into uncontrollable, feral beings known as Mutants, leading to the destruction of civilization.
Biology
Mutants generally evolve into monstrous outcomes, both in terms of their physical appearance and behavior. Some are reversible and tuneable, while others are completely irreversible.
Behavior and Personality
The hostile Mutants Lilac encounters often behave unpredictably; once tuned, they return to their natural state.
