Burner

Angelmaker is the name of a gruesome and ingenious implant crafted within the laboratories of the Church in an effort to boost the strength of the forced soldiers used as a first line of defense in Bastion. An Angelmaker is a metallic cylinder that is inserted into the chest cavity of a humanoid creature, usually at the solar plexus. It roots itself in there and over the course of three days becomes completely integrated into its host. After this, its hosts combat strength is drastically enhanced, though it also leaves its host in an almost fugue-like state at all other times. These hosts are called "Burners".

Once per hour, it can enter into a rage-like mode, commonly referred to as "Burning". While Burning, a wave of heat emits from the host as it conspicuously swells in size and muscle mass, and its capacity for destruction almost doubles. Once a Burner begins to grow, the creature ceases its rampage only when it destroys whatever set it off or when it overheats and drops dead, a smoking husk of overcooked meat.

People assume that those transformed into Burners never regain their minds or previous forms, cursed to remain abominations forever after.
