Autotype

An autotype is a secret communication device used by the Allies during World War II. It transmits and receives a fluctuating electromagnetic frequency that cannot be intercepted. It was invented by Nikola Tesla.

During the late days of the war, Tesla had one of the autotypes in his office in Portsmouth, while another was with Helen Magnus in France.

Only five of these devices were ever build, and by 2010 only the one in the Old City Sanctuary still existed. Tesla used it to contact Magnus when he got trapped in a cave in Colombia.
