Penitentiary 1331 is a high security prison on Tantalus 5.
While it was still under construction, Penitentiary 1331 was attacked by Corroder. Natalie Breez evacuated the workers in a Hero Craft, while Mark Surge, Dunkan Bulk, and Jimi Stringer fought Corroder.
Early in the fight, Bulk was pinned by some steel girders and couldn't be freed. Stringer distracted Corroder while Surge tried to free Bulk.
William Furno was launched in a Hero Pod to help ,but neither him or Breez would make it in time. In desperation, Bulk, Stringer and Surge made a Hero Cell to protect them from Corroder's acid.
Furno arrived and attacked Corroder, ejecting from his pod after setting it on a collision course for Corroder. Corroder was expecting Furno to exit the pod instead of attacking him from behind. The battle raged between Furno and Corroder until Furno was hit by an acid blast while in the middle of a flying kick.
Furno was saved by his acid proof armor, and Corroder retreated at Furno's bluff that a fresh squad of Heroes had arrived.
The Prison was placed under the command of a Veteran Hero. Its history was uneventful until the Breakout, when it was used to hold captured villains while Villain Storage was under construction.
The storage will play a large role in "Vridle's Task"
