An antique bronze telegraph used by the military in the mid-1800s. Its maker is unknown.
Telagraph island is a small island located off the Arabian Peninusula and part of the Oman Islands. It was used as a staging post between England and India. There was a military outpost there in the 1860s, but it was shut down after every soldier that was posted there went violently insane. Since then the islands been abandoned.
Somehow, whenever someone taps the telegraph it interferes with their brain wave patterns (causes a rhythmic disturbance), causing severe hallucinations. Also, the user will keep hearing the telegraph tapping everywhere they go. It displays the qualities of an "earworm" or "sticky tune", a persistent, irritating tune which the hearer can, nonetheless, not get out of their head.As explained in a deleted scene, the telegraph may only effect those whose minds have been conditioned to take orders, a trait shared by Pete with his marine background, and the isolated soldiers from the island.
It was discovered after Warehouse Agent Pete Lattimer played with it out of curiosity, while tracking Brigadier General Laverlong's Elephant Walking Stick at the British History Museum in Lakefield, Illinois. Pete unconsciously began to create a paranoid delusion, gathering details from his life in the manner of a dreamer, and began living in a fantasy world his mind created. It became harder and harder for him to tell reality from fantasy, and he eventually went mad.
Agent Lattimer was returned to reality after his brain was exposed to sensory overload, which seemed to reset his brain and undo the effects of the telegraph. He suffered sensory overload after listening to Tito Puente's Original Studio Master of "Oye Como Va".
