Granule Reduction is a Human man whose actual identity is unknown and kept secret, primarily known for his unique weapons designs that were picked up by SharpTack and a few other companies. Outside of this information, little is known about Reduction. He claims that he was born with a "genetic disorder that slowed his aging process", to explain his unusually long lifetime.
In one of his few public statements made, Granule Reduction declared that he had decided to commit his life to making marginally viable weapons. This phrase “Marginally Viable Weapons” soon became the catchphrase associated with his designs. It is also possible that Reduction is not one person, but several, owing to his long lifetime and seemingly "endless" creativity.
