Legion is an underground organization run by an elusive no-face man named after his company, who employs hitmen to take out whoever they deem necessary. They specifically target those who frequent the dark web, and much like their sister organization, Z, they go after pedophiles. While Z focuses on the trafficking rings and larger operations, Legion was formed to focus on the smaller fish—the psychopaths who lurk in plain sight, fitting into society as the blue-collar working class or with their corporate desk jobs, all the while wreaking havoc on innocent souls when they clock out.
