After he and his friends find the Immunes, Thomas starts talking only to be cut off by a loud crack a section of stone near the East Door breaks off and kills a bunch of people. The Maze reappears in the final book The Death Cure when Thomas realizes that WICKED has hidden the captured Immunes inside of its walls. In the epilogue of The Fever Code, it is revealed that Teresa and Aris kept their memories when entering their Mazes, coordinating everything telepathically on WICKED's behalf. After his friends were sent in, Thomas observed them using Beetle Blades before being sent in the Maze himself by his request (although his memory was wiped without his consent).

It was Aris, Rachel, Teresa, and Thomas' incredible intelligence that convinced WICKED to use them to help build the Mazes. Aris and Rachel, two other teen subjects, worked on the Group B Maze. In The Fever Code, Thomas and Teresa helped WICKED construct the Maze for Group A, working on it until it was complete before entering themselves. Thomas pushed it and successfully shut down the Maze. Chuck realized that "push" was not a word to be typed, but instead referred to a button below the computer console that read KILL THE MAZE. Once the Gladers broke out of the Maze and made it into the Griever hole, Teresa entered the keywords into a computer.

When a month's worth of maps were examined, they discovered that the letters formed the keywords FLOAT – CATCH – BLEED – DEATH – STIFF – PUSH.Įventually, Thomas realized that the keywords were a shut-down code for the Maze. Thomas discovered that letters could be found by placing the maps of the eight sections from the same day over each other. The Gladers had kept records on paper of the Maze patterns for a year or so, and they knew that each month the patterns repeated. In the book, the code consists of keywords which are formed by the walls of the eight sections at the rate of one letter a day. Every night, the Walls of the Maze change, repeating the same pattern every month. They are divided into eight sections surrounding the Glade. The two Mazes are identical in design and described as giant labyrinths. The Mazes can be entered and exited through the Griever Hole. Since they are underground, the sun and sky are simulations and it is always sunny (until the Ending is triggered). Both are built deep into the bedrock that lies under the main buildings of WICKED's headquarters. In the books, there are two Mazes, one for Group A and one for Group B.
