Two significant field divisions of Achroma are the Silver Division and the more recent Rainbow Division. The Silver Division, otherwise known as the Silver Soldiers, is a very large group of fighters between the ages of five and thirty-five who are specifically trained to capture O-Positives. They get their temporary enhancements through the use of Silver Compound. The Rainbow Division is a very new division of Achroma that was created because a group of young O-Positives managed to convince some well-meaning geneticists who'd been archiving them that they could use them instead of locking them away. The current Rainbow Division is just a test to see if this kind of system will work. The current head of the Silver Division doesn't like it.
Having never fought another O-Positive before, because most of them either stay hidden or don't know of their own status, the confrontation ended with both Marvelous and The Strike dead, as well as two-hundred bystanders. Despite the Soldiers intervention, nothing could be done to stop them. They'd evacuated the area as best they could and couldn't coax the Os out of fighting. They came to realize that they had to stop these things before they happen and take out Os while they're weak and unaware. Lloyd and his team began releasing propaganda about Marvelous, suggesting that she was a fraud and that she was just a con artist without any real powers -- that her encounter with The Strike was a publicity stunt gone horribly wrong. O-Positives were dangerous and had to be contained. Lloyd and the new and improved Silver Soldiers began to expand, eventually forming into what is now Achroma, an entire agency bent on studying, observing, capturing, and containing O-Positives to keep society human. O-Positives began disappearing and soon they were forgotten about.
As Achroma grew, different factions began to form. They could develop technology using the radiation emitted from Oratic Crystal, they could research a cure for O-Positivity, study the relationship between genetics and one's O-Signature, and train their Silver Soldiers in efficiently and effectively locating and capturing O-Positives. They'd also been experimenting with cloning. In 1999, the two first successful clones of Katherine Duan, AKA Marvelous, were created, revealing incredibly significant things about how the O-Signature relates to genetics.
In 2014, Achroma's Silver Division would come across five young teens newly infected with Oratic material, and after retrieving them, one of them, an eloquent young boy, would manage to convince the geneticists registering them that they would be enormously helpful in their fight against the inhuman. These geneticists, Dr. Shelley Rodriguez and Dr. Lucius Connolly, would take pity of them and agree to a temporary run. This would prove successful and form the Rainbow Division, an O-Positive counterpart to the Silver Division. Members of heavily monitored, in and out of the compound, through the use of motion-tracking badges fitted with microphones and miniature cameras. Dr. Rodriguez and Dr. Connolly are immediately notified if one of the badges are removes or if they leave the city.
