The Tesla Flexion is a device created by Fred Flexion that allows magicians to communicate across parallel realities or timeline for two minutes.
The Tesla Flexion is a fold between realities, requiring an array of Tesla coils, ultraviolet lamps, and a tented area for the realities to meet. It was successfully performed by Dean Fogg and Julia Wicker, connecting two different realities temporarily together so that Quentin could speak to an Alice Quinn from a different timeline that survived The Beast's attack and became an expert on Shades. In the procedure, people from different timelines were prohibited from interacting physically, as the collision of matter from different realities occupying the same space can create a paradox, i.e. an explosion. The Tesla Flexion has only been successfully employed once before, as it was deemed too volatile when three people died in an attempt to shut it down. Due to the forces at play in the spell, maintaining a connection for longer than two minutes would result in the death of anyone in the vicinity."
The second time it was performed was by Josh-23 and Marina-23. They used the Tesla Flexion in an attempt to get help from Julia-40 and Josh-40. It was successful.
Created by Fred Flexion and has only been successfully used 3 times up to this point that we know of.
Capable of bridging two realities for the span of two minutes. Very dangerous.
