Time fissure

A time fissure, also called a timeline fissure, (PROSE: The Day of the Doctor) was a weakness in time and space, a rent in the fabric of the Web of Time itself.

Structure
Described as a "crack in Time" by Charley Pollard, a time fissure could rupture at one point in time and stretch to another point through the Time Vortex. One time fissure ruptured in the mid-21st century and ended in the 16th century. (AUDIO: The Time of the Daleks)

Time fissures occurred all the time, but were so small they barely affected the space-time continuum as they stemmed from decisions such as taking cream or jam on toast. Larger events, such as the sinking of the Titanic where hundreds of lives were affected, could create fissures where time tracks diverged from a nexus point, allowing for travel to a parallel universe. (AUDIO: The Wreck of the Titan)

Common effects


A person who stepped into a time fissure would become lost in time, (TV: Image of the Fendahl) although a fissure could be created to allow travel between specific times. (TV: The Day of the Doctor) They were often responsible for disappearances, as people accidentally wandered through them and got lost in time. (TV: The Temptation of Sarah Jane Smith)

Places that were reputed to be haunted often had a time fissure nearby, which caused a time distortion. Growing up near a time fissure tended to enable one to develop psychic powers such as precognition and "second sight". (TV: Image of the Fendahl)

Fissures affected the space/time events around them, turning possibilities into tangible realities. (AUDIO: The Time of the Daleks)

History
One fissure was created when a War TARDIS was shot with a D-Mat Gun as it attempted to dematerialise in Antarctica in 12,000,000 BC. The damaged TARDIS stretched to 1999, creating a fissure running between the two times. (PROSE: The Taking of Planet 5) Around the 1970s, this fissure ran near the English village of Fetchborough. (TV: Image of the Fendahl, PROSE: The Taking of Planet 5) Because of her long exposure to the fissure, Martha Tyler had a reputation as a witch. The presence of the fissure made Fendelman's experiments with "Eustace", the skull of a Fendahl Core, even more dangerous. (TV: Image of the Fendahl)

Sarah Jane Smith, Mike Yates and K9 Mark III visited a house built over a time fissure. (PROSE: Housewarming)

A time fissure opened seven miles from the former site of Foxgrove; connecting London in the 2000s to Foxgrove in 1951. Sarah Jane Smith and her team investigated it and Sarah Jane used a device to open and close the fissure. When activated, the fissure manifested as a glowing portal through which people could pass. (TV: The Temptation of Sarah Jane Smith)

The Daleks in the Time Vortex deployed a Temporal Extinction Device within a time fissure. This caused instability. (AUDIO: The Time of the Daleks)

The Moment opened a time fissure to show to the War Doctor his future incarnations in an effort to stop him from destroying Gallifrey. (TV: The Day of the Doctor)
