Memory Walk

Memory Walk, also known as torture by chagrin, was a Force ability that consisted of mentally reaching into the victim's mind, forcing them to relive all the worst memories of their life, both painful ones and ones that were merely embarrassing, over and over and over again to the point where it almost seemed to cause physical pain. Discovered by the Sorcerer Rokur Gepta, he found that after a brief session of torture by chagrin, the subjects demonstrated a slight increase in intelligence and efficiency after they recovered. For this reason he used it regularly on the crew of his personal command ship, the Wennis.

Memory Walk was used over the millennia by various dark side groups, including the Sorcerers of Tund and the Order of the Sith Lords.

Githany used this power to force Bane to reconnect with the dark side and move past his fear and concern of the Force, a power she had been taught by her Jedi Master when she had similarly lost touch with her mental hold over the Force.

When Gepta captured Lando Calrissian, he planned to use torture by chagrin to kill him. Half an hour of it and Lando was in pain like he'd never known before; Gepta believed he could make Lando last for several weeks before the gambler's mind finally snapped and he died. To make the process more personal, the Sorcerer of Tund had created a machine which would amplify his power and allow him to pick and choose which memories Lando would relive. The machine would also let Gepta alter the memories to be even worse than they were already. Fortunately for Calrissian, a squadron of Renatasians attacked, distracting Gepta long enough for the gambler to execute a plan to escape.

Nearly a century, later this ability was used by Darth Maladi and Cade Skywalker against each other on the world of Wayland. Darth Wyyrlok III wielded this technique in his duel against Darth Krayt.
