From: Sime Surgeon, Ch 10. (Digen and Ilyana scene) 'He came at her then, across the width of the room, in tenth level augmentation and at the same instant contact was made, he employed an old, old Zeor technique, invented, it was said, by Ray Farris, Klyd's father, for deconditioning. By inducing the ultimate, primal Gen fear in a House candidate, and forcing the Gen to stand up to it in full lateral contact, all psychologically conditioned fear could be wiped away in one traumatic event. It was a kill-or-cure technique reserved to the last-ditch battle and used only on repeated and sincere request of the Gen.'
Note: "Ray Farris" -- mentioned above, is GRANDFATHER in the wiki --- Ray Kolin Farris.
