Grievers

Grievers are large mechanical spider-like creatures who roam the Maze when The Doors shut.

For each sector/section there is, a griever belongs there, & must return at sunrise.

The Grievers are specifically made for manuevering around the Maze easily.

The Grievers are engineered by W.C.K.D and baby grievers also exist within the W.C.K.D Compound in The Scorch Trials. Some Baby Grievers are seen in the maze sometimes but its rare to see them.

When stung by a griever they emit some sort of substance within the holder which causes them to go mad- this is called "The Changing" by the Gladers.
