Early expeditionary accounts document the devastating psychological deterioration upon seeing a Zanshi'Oni. Before falling into a gradual but profound madness, witnesses have described the Zanshi'Oni as a shadowy creature with a mesmerizing veil over its head. Observers have also stated a momentary state of paralysis while staring at this hypnotizing veil; motor control suddenly returns after the Zanshi'Oni vanishes. With this information, Yolonaut Oracles speculate that, after making contact, Zanshi'Oni continuously feed off their victims' psionic energy. Current experimental trials show the application of Esthrea Cilia to be effective in managing Zanshi'Oni-induced symptoms.
