What is Orison?

An orison, although introduced in the first "Sonmi" chapter is not fully explained until "Sloosh'a's Crossin'." An orison is an egg-shaped object that functions as a sort of tape recorder, as well as a communication device, by projecting a hologram image of the recording. In the "Sonmi" chapters, Sonmi-451's interview is being preserved as an orison. It is also this device by which Meronym communicates with her fellow Prescients in "Sloosh'a's Crossin'."
