Chronovore The Chronovores were god - like transcendental being s who , as their name implied , fed on time itself . They were greatly feared , and sometimes respected or worshipped , because of this . Nature . The Chronovores existed on another plane outside the universe , ( PROSE : " The Dark Path " ) and as such , they were generally uncomfortable in the universe due to the lack of physical dimension s . ( PROSE : " Blood Heat " ) They lived in the Time Vortex but ate and fed in the Six - Fold - Realm , otherwise known as Calabi - Yau Space . ( PROSE : " The Quantum Archangel " ) They could also be found in the black void surrounding the universe where it was still expanding , ( PROSE : " No Future " ) or in the Morass . ( COMIC : " The Crimson Hand " ) The Seventh Doctor considered them the Third Law of Thermodynamics incarnate . ( PROSE : " " ) They were time sensitives like their cousins the Eternal s , ( PROSE : " The Crystal Bucephalus " ) also being cousins to the Temperon , as well . ( AUDIO : " The Sirens of Time " ) However , the Guardians of Time viewed them and the Eternals as their " own children , " and the Master called them the Guardians ' " bastard children , " the dark caste of the Chronovores being segregated at birth from the Eternal caste and consigned to exile because they failed to meet the standards of the Council of Guardians , based on their description in the Ancient Covenant s . According to the council ' s ruling , the Chronovores were nothing but vampire s : subsisting on the primal energies of the Six - Fold Realm , only truly living by drawing the life essence from the moments of choice , where they could thrive on the what - ifs and the what - might - have - beens , keeping the cosmos alone in the multiverse . Like the Eternals , Chronovores were built from matrices of exotic particle s , resonating superstring s that gave them power and majesty . They were living nonbaryonic matter , made from the very fabric of time itself , and in their natural form the Chronovores existed as six - dimensional polymorphic lattices of non - baryonic matter ( like photino s and chronon s ) , bound by superstrings . ( PROSE : " The Quantum Archangel " ) They originally fed on the raw energy of star s ( PROSE : " The Dark Path " ) before evolving . Their primary food source was the Lux Aeterna , from which they gained sustenance . However , they also fed on the timelines of people ( especially liking the history of a Time Lord ) , planets , alternate worldline s , and entire realities , timelines and parallel universes being rare feasts . As they feasted , the reality would darken and corrupt , " blossoming with the fruits of its self - destruction , " which added flavour and spice to their consumption . ( PROSE : " The Quantum Archangel " ) Appearance . Chronovores appeared as pure - white humanoid s with small wings and helmet - like heads , firebirds of life and fire , but they could easily change their shapes like other transcendental beings , usually taking on feminine forms . ( TV : " The Time Monster " ) Artemis , described simply as a " bird - woman - thing " , ( PROSE : " Conundrum " ) generally assumed the form of a woman in black , with black hair , red nails , and a red mouth of perfect teeth . She also wore a crown of thorns and diamonds , and manifested as a multi - dimensional mouth at one point . ( PROSE : " No Future " ) Kronos had several appearances , as a man , a woman , and something like both , and appeared as all Chronovores in order to trick the Master into thinking the entire race was after him . ( PROSE : " The Quantum Archangel " ) Powers . In addition to their feasting on time and erasing people and things from history as a result , the Chronovores had great powers to shape reality , such as rescuing two TARDIS es from a time ram . ( TV : " The Time Monster " ) In her service to the Monk , Artemis changed events so that the Silurian Morka was able to kill the Third Doctor without the possibility of regeneration , thereby creating the Silurian Earth ; ( PROSE : " Blood Heat " ) she again changed the Doctor ' s history so that the Garvond could come into existence ; ( PROSE : " The Dimension Riders " ) she ensured Huitzilin ' s survival ; ( PROSE : " The Left - Handed Hummingbird " ) she pulled a boy named Jason from Earth and installed him as the Master of the Land , after recreating the Land of Fiction from the ashes ; ( PROSE : " Conundrum " ) and freed Varda from its time loop , enabling an invasion of 1976 Earth that never happened . She later retroactively saved the Seventh Doctor from a fatal shot , made the Monk ' s mouth disappear and materialise a giant fishing hook through it , and changed history so that Ace saved Brigadier Lethbridge - Stewart ' s life . Because of this new timeline , Ace never set Artemis free , ( PROSE : " No Future " ) but as the Chronovores existed outside of time , they were unaffected by temporal paradox es . Additionally , a large number of Chronovores created a natural jamming field which made TARDIS dematerialisation impossible . Kronos also created the construct Paul Kairos , a part of Kronos but also a real individual human , who was able to remove the Profane Virus of Rassilon from the Doctor ' s TARDIS . ( PROSE : " The Quantum Archangel " ) In terms of weaknesses , a point - blank artron pulse from an artron cannon tore their forms , and they could become poisoned by Klypstrømic warhead s that irradiated the vortex , leaving them weak and broken . But even these weapons were " small fry " to Chronovores , with vortex lance s being ineffectual and Earthshock bomb s being an irritation . Under the onslaught of the Eye of Harmony , their polydimensional matrices shattered and evaporated , while those caught on the edges were left broken , injured or dying . Otherwise , like the Eternals and other Transcendental Beings , the Chronovores could will themselves dead , and this was considered the only way they could die . When Kronos committed suicide , the amount of sheer energy released sent ripples through the cosmos , felt by those sensitive to time , and disrupted the space - time continuum , detonating the Great Attractor ( the largest black hole in the known universe ) and causing it to explode . ( PROSE : " The Quantum Archangel " ) The blood of an Eternal was able to restrict Chronovores , suppressing their power . ( PROSE : " No Future " ) Interaction with other races . The Chronovores were feared and hated by most other races , especially the Eternal s who viewed them as parasites , uncontrollable beings of fire and ice and unutterable cruelty , ( PROSE : " The Quantum Archangel " ) and even the Third Doctor suggested Kronos to be a threat to the entire created universe , ( TV : " The Time Monster " ) the general consensus being that it was better not to attract the attention of the Chronovores to the normal universe . More than tens of thousands of Chronovores made up the all - powerful Divine Host , the shock troops of the race . Only a few Chronovores roamed the universe at any time , spotting the few alternate timelines as they formed and devouring them , as they were unable to enter what they called the " Higher Place " ( the space - time continuum ) unless they were summoned . According to the Ancient Covenants that governed them , once a link was forged between two regions , either spatial , temporal , dimensional , or otherwise , the Chronovores were free to pass between them . ( PROSE : " The Quantum Archangel " ) They were summoned through rituals , one in particular that involved a pentangle with the blood of five races whose genetic destinies had been altered by the Capitol on Gallifrey : Minyan , Silurian , Dalek , Human , and Mandrel . A Chronovore would consume the blood , making an image of the being appear and move around the pentangle as it grew older and died . Artemis commented that it was always the " same races . " ( PROSE : " No Future " ) Not being " normal life " or existing in the universe , concepts like " pain " and " obey " ( PROSE : " Blood Heat " ) were not understandable . Neither were the concepts of using metaphors or a language or having a personality , and Artemis was content to eating Earth and every human as they had such short lives anyway before the Doctor convinced her she had a merciful personality . She did find mortals could be entertaining . For freeing her , however , she willingly granted Ace a wish . She warned the Seventh Doctor to never tell a Chronovore to ' stop ' as it annoyed them . She , if not all Chronovores , thought it laughable that Time Lords felt they owned Time , like how fish thought they owned water ; she stated that fish at least could feign ignorance as they had never heard of fishermen . ( PROSE : " No Future " ) History . The ancestors of the Chronovores originally lived in the normal universe , able to move across time as other species moved across space . In the event that one of their kind grew tired or became ill and were stranded somewhere at some time , they built the Darkheart , a space / time conduit and medical device , to transmit energy to any point in space and time . They eventually evolved into a higher plane outside of time , ( PROSE : " The Dark Path " ) although another account claimed they were spawned by the Great Old One s and were billions of years old . ( PROSE : " The Quantum Archangel " ) Breaking the Ancient Covenants , the Eternal Elektra and the Chronovore Prometheus conceived a child , Avatar , and were confronted by the Guardians as the Six - Fold - God in the darker strata , deep within the time vortex . Prometheus ' s existence was undone and Elektra was taken away , the darker strata being shunned and disowned and wiped from the collective memories of both races because of the horror and collective shame of summoning the Six - Fold - God . Later , Lillith , matriarch of the Chronovores , petitioned for the Avatar to be destroyed , but the God spun a crystal and imprisoned the Avatar , which would later be known as Kronos . The crystal appeared on many world , eventually arriving on Daemos before the Daemon s brought it to Atlantis on Earth . Although used benevolently and worshiped , when the Master accessed the crystal in an encounter with the Third Doctor , Kronos was released earlier than intended and went mad , destroying Atlantis . ( TV : " The Time Monster " , PROSE : " The Quantum Archangel " ) Two Chronovores roamed the Vortex while Ramón Salamander was drifting through time towards Earth . ( COMIC : " The Heralds of Destruction " ) In 2003 , as revenge against the Chronovores , Kronos tricked the Master into cutting off the Lux Aeterna . However , in the process the Quantum Archangel was born and , in an effort to give all seven billion people on Earth their ideal reality , she created seven billion parallel universe s around the planet . As this was their only food , the Chronovores swarmed the Earth and began feeding slowly , acting like parasite s and not carnivore s so as to prolong the feast for eternity . Working with the Sixth Doctor , Kronos sacrificed himself and detonated the Great Attractor , giving the Lux Aeterna a way home and allowing the Chronovores back into the Six - Fold - Realm . ( PROSE : " The Quantum Archangel " ) The Chronovores were present at the Timewyrm ' s creation , bestowing the name upon her . ( PROSE : " " )
