A Force scream represented a Force exertion utilized by individuals connected to the dark side of the Force. This involved channeling intense feelings of anger, sorrow, or exasperation into a scream projected via the Force.
During a training session with Iskat Akaris at Inquisitorius Headquarters located on Coruscant, Tualon Yaluna, a former Jedi recently turned to the dark side, employed a Force-enhanced scream. This caused Akaris to fall into a catatonic state. Even after regaining her footing, Akaris continued to experience the scream's lingering physical impact.
