Web of Time The Web of Time or Spiral Politic , also called the Kaliyuga , was the orderly structure of time , built and maintained by the Time Lord s . It was Gallifrey ' s noosphere . Overview . Rather than being a necessary fundamental aspect of the universe , it was a meta - structure created and imposed on history by the Time Lords ( AUDIO : " Neverland " , PROSE : " The Book of the War " ) during the anchoring of the thread , ( PROSE : " The Book of the War " ) in which Rassilon used the Eye of Harmony as " the hitching post of chronology " . ( AUDIO : " Neverland " ) Before this , the universe had no history or defined set of physical laws . ( PROSE : " Christmas on a Rational Planet " ) The Web could become unbalanced by the changing of events that had significant effects . For instance , the Sixth Doctor once explained that the Web of Time would be disrupted if Earth were destroyed in 1985 , ( TV : " Attack of the Cybermen " ) as Earth was a nexus world linked to the destinies of many major intergalactic powers . The saving of the " Titanic " would have similarly perturbed the Web by condemning all the later ships that were saved by round - the - clock radio surveillance , lifeboat capacities , or the International Ice Patrol , all of which were developed due to the " Titanic " s sinking . ( PROSE : " The Left - Handed Hummingbird " ) Even concerning events that were not fixed points , time could be crystallized along a particular web - way , ( PROSE : " The Sands of Time " ) making that event a fixed part of the Web of Time so that it had always happened and would always happen . ( PROSE : " Attack of the Cybermen " ) This could occur when a person learned about their personal future . ( PROSE : " The Sands of Time " , TV : " The Angels Take Manhattan " ) This effect was first predicted by Blinovitch . ( PROSE : " The Sands of Time " ) An imbalance in the Web could cause disastrous repercussions in every corner of the universe , killing billions , instantly disappearing major civilisations , and threatening the fabric of the universe itself . ( PROSE : " Attack of the Cybermen " ) However , an amaranth could be used to rebuild unstable or discontinuous elements of the universe ( PROSE : " Christmas on a Rational Planet " ) along the lines of the established laws of the Spiral Politic . ( PROSE : " Against Nature " ) Specific events could sometimes be removed from the Web , but analogous events would take their place . ( PROSE : " The Left - Handed Hummingbird " ) For instance , if Adolf Hitler was prevented from rising to power , a different man would have still taken control of the Nazi party and begun World War II , though the War would ' ve ended differently . ( PROSE : " " ) The Seventh Doctor once rewrote history so that his friend Remnex died in his sleep rather than being murdered by a dagger through the eye . ( AUDIO : " The Dark Flame " ) The Spiral Politic did not encompass the entire universe . Like with any noosphere , the Great Houses had great difficulty penetrating or even observing some areas around or beyond the Spiral Politic ' s edges , collectively known as the frontier in time . The Anvil Star s region was near this frontier in time , as were the planets Zo la Domini and Simia KK98 and the community Ascension . ( PROSE : " The Book of the War " ) The Tenth Doctor said that the Time Lords never endeavoured as far into the future as the year 100 , 000 , 000 , 000 , 000 ; ( TV : " Utopia " ) the Eighth Doctor ' s TARDIS would only take him as far forward as Endpoint , and then it needed to recalibrate before it could dematerialise again . ( PROSE : " Hope " ) Events in the Web of Time . Events the Doctor stated as being part of the Web included the destruction of Mondas , ( TV : " Attack of the Cybermen " ) the sinking of the " Titanic " , ( PROSE : " The Left - Handed Hummingbird " ) the destruction of the Halcyon race through the Ice Warrior s creating an atmosphere on Halcyon more suited to them , ( AUDIO : " The Resurrection of Mars " ) Deimos becoming an artificial sun that heated Mars , ( AUDIO : " The Resurrection of Mars " ) Gallifrey ' s Racnoss Wars , ( AUDIO : " Empire of the Racnoss " ) the burning of Joan of Arc , the assassination of Francis Ferdinand , ( AUDIO : " Cobwebs " ) the Manussan Empire overthrown in Manussan year 2326 , ( AUDIO : " The Cradle of the Snake " ) Magnus Greel dying in the 1800s , ( AUDIO : " The Butcher of Brisbane " ) and human ity ' s 50 - year war with the Eminence . ( AUDIO : " The Death of Hope " ) Events in the Web that were explicitly recorded in the Matrix included the " R101 " crashing and all passengers dying , Adolf Hitler becoming Chancellor of Germany ( and being alive to continue World War II ) , Edward VIII abdicating the British throne , German forces invading Poland , the evacuation of Dunkirk , Peladon entering the Galactic Federation , Zephon overthrowing the Embodiment of Gris , Mavic Chen being elected Guardian of the Solar System , Dalek forces assembling on Kembel and being engaged with the Movellan s in 4 - X - Alpha - 4 in 4949 , the Cult of Morbius being established , plans for the Doomsday Weapon being stolen by the Master , Chancellor Goth visiting Tersurus , President Romana and Etra Prime being taken by the Daleks and the subsequent Dalek invasion of Gallifrey being repelled by Romana , and a Dalek time fleet being captured in the Time Vortex . ( AUDIO : " Neverland " ) Charley Pollard was added to the Web when she saved it , not having died in the crash of the " R101 " as had been recorded . ( AUDIO : " Storm Warning " , " Neverland " ) References . The Sixth Doctor believed summoning a Chronovore onto 21st century Earth threatened the Web of Time . ( PROSE : " The Quantum Archangel " ) During the first battle of the War on Dronid , the Great Houses discovered that the enemy had constructed their own meta - structure of the universe to replace the Spiral Politic . ( PROSE : " The Book of the War " ) The Celestial Intervention Agency - operated Klyst Institute arranged to recruit their test subjects at the end of their lives in order to preserve the Web of Time . ( AUDIO : " Unregenerate ! " ) Since the Yssgaroth emerged during the creation of the Spiral Politic , the Yssgaroth taint remained in the fabric of the universe , irremovable except through the unweaving of time itself . " The Book of the War " speculated that the Yssgaroth were areas of hostile anti - structure produced by the collision of the Spiral Politic with Spiral Yssgaroth , which had structures and protocols completely hostile to those of the Spiral Politic . ( PROSE : " The Book of the War " ) A backup of the Spiral Politic was stored in the Great Houses ' prison , which stood outside of time so that it could be remapped onto the universe if time was ever altered . ( AUDIO : " A Labyrinth of Histories " ) Ancient Gallifreyan prophecies recorded in the Matrix forewarned that the Hybrid , standing in the ruins of Gallifrey , would proceed to unravel the Web of Time .
