Your average caped crusader generally takes one of two paths: the faithful hero, who captures criminals and turns them over to the police for a fair trial in the justice system; or the vigilante, who captures criminals for themselves and act as judge, jury, and in the most extreme cases, executioner. The ladder was obviously unacceptable for any hero who wants to be good with the press. But, the former has its presumptions as well: the justice system is far from ideal. Judges are too often unfair and prejudiced, punishment can be inhumane and costly, and better funded criminals can simply evade the system entirely. Imprisonment can also be horrifically inhumane for metahuman offenders, since more restriction is called for than a cell.
The heroes Ferron, Semblance, and Cyber Falcon sought a middle-ground solution between the faithful hero and the vigilante. The principle, anyone can be redeemed and rehabilitated to a productive member of society. So, they founded The Redeemers, a supergroup focused on capturing metahuman criminals and rehabilitating them in their private facility, outside the problems of the justice system and Hardlocke.
Redemption Hall serves as the strategic HQ as well as the rehabilitation center for "customers" they're referred to as. The lowest level is where customers dwell and go about their treatment. It's a virtually impregnable fortress in function, but a friendly clinic in aesthetic. Ferron's engineering firm designed the inner workings, titanium-gold walls and supports with various energy-based defenses to maintain physical security. Semblance's illusion magic also plays a part in keeping customers inside during their six-month sentence. Falcon Sciences manages the psychiatry and psychological treatment, the most labor-intensive aspect of the facility. The upper levels hold the Redeemer's operational headquarters: the flagship members' personal quarters, and various conference and implementation rooms to enact the Redeemer's vision.
Before a mission is even executed, a tentative treatment plan is formulated for a would-be customer. This way a customer doesn't sit in a cell while the paperwork is done. Treatment plans are specialized per metahuman based on their abilities, neuroses, and resources. A containment plan must of course also be designed to prevent the customer from escaping treatment. At the end of a treatment, customers are released to halfway houses throughout the city. Unlike the rest of the treatment, these do liaison with government social work to find customers jobs and housing within the general populace. The most successful treatments are even referred to other hero groups, so that they may use their powers to make the world a better place. Some of these customers have even become flagship members of the Redeemers.
Being that their goal is to redeem criminals rather than punish them, the Redeemers have a strict no-killing stance, even when threats use lethal force. When a previous customer becomes a redeemer and breaks this nonviolent stance, they are immediately re-admitted into a treatment program back in the lower levels of Rehabilitation Hall.
