"The mat-er-i-op-ti-kon."

The materioptikon is a powerful weapon invented by Dr. Destiny, which allows him to turn his dreams into reality. The ruby materioptikon is the second version, made from Dream's lost ruby. When Dr. Destiny says his mother gave the ruby to him he means originally; only the amulet was given to him in prison, hence the need for him to escape andĀ find the ruby.
