Space-time shadow
From Tardis Wiki, the free Doctor Who reference
A space-time shadow was the after-effect of a time eddy.
After a time eddy displaced a person in time, a space-time shadow was created out of their experiences. Audrey Mohinson was able to harness these and project them into the immersive reality game Fugitives to provide more exhilarating experiences for those playing and, by extension, hold back the threat of the Ravagers. (AUDIO: Food Fight) However, if this feedback loop was broken without any changes to the Ravagers, the resulting error could cause the implosion of the universe. (AUDIO: Cataclysm)
