The practice of seeking guidance from the beings which are believed to control one's universe has a long history. Several ideologies claim that their chosen deity was consulted about possible futures before the beginning of this universe. The kza'rylll claim that their prophets can fortell the outcome of quantum events (In reality, they merely alter the chirality of the continuum surrounding their tests.). A very large number rely on simple precognition to determine the future - however, knowing the future often changes it.
Unlike other oracles, the Imperial Oracle is always accurate (Although reality may not always be). It was based in spirit upon the_katherine_interface and in code on Matt Wright's random image displayer.
