Stonghold is the preeminent paranormal prison in America, located inside a hollowed-out mesa in Arizona. Stronghold Containment Teams used to be on standby in NYC and Indianapolis, with others on-call throughout the country, ready to step in to collect and transport villains after the heroes had kicked butt.
After The Gap, the prison was emptied and the Containment Teams disbanded. Now that the villains are being recaptured, partial funding has been restored and the facility is receiving a massive technological makeover, to improve security. A Containment Team is back up and running in NYC, but not yet fully operational in Indianapolis.
