This is one sprawling labyrinth of levers and buttons.  Press or flip anything you find. There is no particular sequence that needs to be followed. You will however backtrack several times in order to progress forward. The red indicates doorways opened by levers or buttons. There are several secret areas ( green) that contain treasure.  When you finally reach Escaton he asks you three riddles.  Now if one had a page torn from a book, perhaps a riddle book, one would have no difficulty in finding the answers needed.
