The Baumann Parahuman Containment Center, better known as the Birdcage, is a prison for parahumans that have committed crimes severe enough that they must be removed from society. It is not designed to allow prisoners to leave after they have been imprisoned within it, as prisoners need to be teleported in, there is no ways in or out of the prison.


The Baumann Parahuman Containment Center was presumably built in 1996,[1] and probably not by Dragon.[2]

Behemoth presumably tried to attack the Birdcage in 2001.[3][4]

Since its inception it has only been taking on more and more inmates.[5]

In the wake of Scion's attack, the Birdcage was opened and its inmates released to assist in the fight.

Known PrisonersEdit


The Baumann Parahuman Containment Center is located inside a hollowed-out mountain in British Columbia, part of the greater Rockies mountain range.


The Baumann Parahuman Containment Center was maintained by Dragon. It is inside a hollowed out mountain whose walls are lined with ceramics that were designed by Dragon, each layer of the mountain contains dormant containment foam, which will automatically start expanding upon a wall breach. Inside the mountain is a vacuum, and three thousand anti-gravity drones, which will detonate upon an abnormality. Some of them contain containment foam and some are much more lethal.

The prison itself is suspended inside the mountain by the same pipes that supply it with its supplies (such as books, blankets, cigarettes, food, water and air, and other objects), it is also split up into wings, the walls between which are negligible, allowing all the prisoners to intermingle. Although the cell blocks are usually run by someone and some are very organized, such as Marquis' block, block W.

Teacher surmised that there may actual be a spatial warping device that makes the entire prison no bigger than one's fist. This is why it would be nearly impossible for someone to break out.[6]

  2. I can say that Dragon is not a tinker at the core level and that you can look at the date the Birdcage was created and the date she was made and that it's fairly obvious she co-opted the technology at one point. The facts don't add up otherwise. - Wildbow on Reddit

  5. “It’s not worth it,” West said.

    “A moderate risk for a chance to save hundreds, thousands, even millions of lives,” Armstrong said.

    “How many lives do we lose because of the monsters we set free?” West retorted. “Those criminals were put there for a reason.”

    “At first,” Armstrong said. “But the rationale for indefinite detention has been getting weaker, and the number of capes going in has been increasing. I-” - Excerpt from Scarab 25.1
  6. The Birdcage was nicknamed such because the prison dangles. It’s basically set inside a hollowed out mountain and the tube/elevator system that transports prisoners down is also the same (and only) thing that keeps the prison from falling.

    Originally, the Birdcage was conceived of in ‘The Cat and the Canary’, wherein Canary was the main character, and Siberian was a notorious inmate, who decided Canary was her newest victim. I make a nod to this draft when someone mentions in-story that Siberian is one of the only individuals who could break in/out of the Birdcage. (I do this a lot, actually). - Comment by Extinction 27.4
