A receiving-telepathic-dominant psyker with minor photo-kinetic abilities,[1] Gideon is one of the four semi-successful experiments in triggering the psionic potential of human brain. The injection of FEV into his brain resulted in what can be best described as practical insanity. As he has no control over incoming thoughts, his mind is constantly flooded with outside thoughts whenever he is not carrying his psychic nullifier.
Destroy the Mutant leader.: Gideon informs the player in a roundabout way that the Master is protected by a corridor of revulsion, made up of failed experiments of his. The player can convince Gideon to give him the psychic nullifier to protect themselves.
