Nine Gallifreys The Nine Gallifreys or Nine Homeworlds project involved the cryptoforming of eight planets into eight clone worlds of Gallifrey . ( PROSE : " The Shadows of Avalon " , " The Book of the War " ) It was originally planned by Greyjan the Sane ( PROSE : " The Ancestor Cell " ) and eventually spearheaded by House Mirraflex ' s Lady Armourer Mantissa and House Lineacrux . Officially , each Homeworld was run by a caretaker House as a potential replacement if the original Homeworld were destroyed . However , the backup Homeworlds also acted as decoys , with each having its own War King or War Queen and thinking it was the original . There was a supposedly - total ban on contact between Homeworlds , but Mantissa eventually went into exile on one of the duplicates , ( PROSE : " The Book of the War " ) and by the time of the fall of Mictlan , travel between Gallifreys was often performed by the War King and his agents . However , even after travel between Gallifreys became common , not even the War King knew which was the original . ( PROSE : " The Taking of Planet 5 " ) Since each thought it was the true original , the secondary Homeworlds each created their own tertiary Homeworlds ; some House Military strategists hoped this would end in every planet being turned into a Homeworld . ( PROSE : " The Book of the War " ) Some Gallifreys were hidden in pocket universes ; ( PROSE : " The Taking of Planet 5 " ) one Great House ( AUDIO : " The Eleven Day Empire " ) notably created a homeworld on Christine Summerfield ' s Earth in the bottle universe . ( PROSE : " Dead Romance " ) A human colony - world was cryptoformed by the Great Houses into a Homeworld between 3560 and 3591 , and some of its inhabitants like Verrifant were mutated into regen - inf soldiers . ( PROSE : " The Book of the War " ) Six years before the War , the War King became Lord President of what purported to be the original Homeworld , and he continued in that role for over half a century . ( PROSE : " The Book of the War " ) When Compassion became the first 102 - form timeship two years before the War , ( PROSE : " The Book of the War " ) Romana was also War Queen ( and " Mistress of the Nine Gallifreys " ) on what seemed to be the original Gallifrey . ( PROSE : " The Shadows of Avalon " ) This Gallifrey was invaded by Faction Paradox and destroyed sometime before the Eleven - Day Empire was destroyed in the War ' s fiftieth year ; ( PROSE : " The Ancestor Cell " , " The Shadow Play " ) at that time , the Faction claimed to have also written the backups out of existence . ( PROSE : " The Gallifrey Chronicles " ) The incident where a Gallifrey was first lost was called the battle of Mutter ' s Cluster . At the time , this brought the " official " total down to nine . ( PROSE : " The Taking of Planet 5 " ) Sometime after the wiping of the original Gallifrey , in which most Time Lords perished , Homunculette was taught the basics of escapology by War Cardinal s at a training complex on Gallifrey XII . ( PROSE : " Alien Bodies " ) Homunculette and the Lord President once visited Gallifrey Eight , which contained loomstack s and chronoforge s to create weapons and soldiers for the Time Lords . ( PROSE : " The Taking of Planet 5 " ) In her lecture " The Cultural Impact of War - Time " , Entarodora noted that more Homeworlds had been lost " than might be thought prudent " . She argued that the total number of War - time deaths by Great House members was nonetheless small because the inhabitants of these other Homeworlds were " mere - sheath echoes " of a " core probability " . At least one Homeworld was predicted to be destroyed upon the destruction of the Hydra - Centaurus Cluster by the Grandfather ' s Maw around the year 60 , 000 , 000 , 000 .
