The Invisibility Ray was a small prototype device created by the Nazis which allowed their agents to become invisible for short periods of time. Powered by a particular grade and a size of diamond for its lens, the ray was used for a series of diamond thefts from American museums, which also involved stealing electrical components, that had become known as the "Wraith Robberies" by a newspaper.

When four spies attempted to take the diamond from a museum connected to a group of adventurers, the adventurers moved to sabotage the device, or stop it from returning to Germany to prevent construction of the machine proper.
