- "Ben of the Builders, you've been sentenced to Banishment for the attempted murder of Thomas the Newbie. The Keepers have spoken, and their word ain't changin'. And you ain't coming back. Ever."
- — Alby, The Maze Runner
A Banishment is an official punishment given to a Glader who had committed a serious crime, and involves said Glader being forced into the Maze as the Doors shut for the night. This punishment had to be decided on by the Keepers. Banishments were held in public where everyone could see, presumably to make the other Gladers realize what would happen if they violated the rules. The Gladers always found the collar of the banished Glader the day afterwards just outside the Doors.
The Banishment of Ben
Ben goes completely insane after going through the Changing. Later Newt says no one has ever gone as bad as Ben before. When Thomas was in the Deadheads, Ben suddenly appears from the woods, acting like a complete psycho, accusing Thomas and saying that he is the one who should be killed. Ben then attacks him with a knife. Alby sees it and stops him from hurting Thomas. The day after that, the Keepers drag Ben out by force. The Keepers, using a large pole with a collar, shove Ben outside the Glade, into the Maze. Ben's last screams are blocked out when the walls close. He was presumably killed by Grievers during the night.
- Newt said there had been three Banishments, excluding Ben, all as nasty as the one Thomas had seen.
- The Banishments use a long aluminium pole comprised of multiple smaller poles that fit together to make one. The end pole has a leather collar for holding the person in place and can be detached to pull the rest of the pole back into the Glade.
