"Tom, I just triggered the Ending."
— Teresa to Thomas in The Maze Runner
The Ending was an important event in the Glade. It began when Teresa entered the Glade, and included the removal of the Glade's sun, and caused the doors of The Maze to remain open at night. This was also the point at which The Creators stopped giving weekly supplies to the subjects, thereby forcing them to venture outside the protection of the Glade.
