Conduit

A conduit is a connection that an individual has to the World of Forms. Since the conclusion of Season 4: Valentine every character (both player characters and non-player characters) has had one of these connections. Conduits manifest based on the personality of the character in question and can change if that character undergoes dramatic character changes. Most conduits tend to manifest in low-key ways such as aptitudes for certain tasks. However given the nature of the show most of the player characters and the characters they encounter have flashier conduits that can manifest as special abilities.

Origin of Conduits
In Season 4: Valentine Aeron creates a machine called the Einsoft which allows those who use it to connect to the World of Forms and become a conduit.

At the culmination of the season the destruction of the Einsoft by Team Loser looses its power into the world, causing every single sapient creature to become a conduit.
