Galactic Council The Galactic Council was made up of emissaries of the Outer Galaxies with the Dalek s , who headed the Great Alliance . History . Early history . Some point before the 21st century , the Galactic Council allowed the Vorshagg membership into the Council and founded the Galactic Heritage . ( PROSE : " The Tomorrow Windows " ) In 1902 , a group of Judoon working for the Council were conned into assisting in a plot to use Temporal Reversion Device s on Earth . ( PROSE : " Revenge of the Judoon " ) The Great Alliance . The black Dalek Supreme had established the Galactic Conference to conquer the Solar System . They had their headquarters on Kembel , with a secret underground base containing thousands of Daleks prepared for war . The representatives met in a city on the jungle planet in the year 4000 . On the Council , the Black Dalek represented the Daleks . Malpha , Beaus , Gearon , Sentreal , Trantis and Warrien made up the other council members . Though not present then , Zephon , master of the Fifth Galaxy had persuaded Beaus and a new delegate , Celation , to join . The human Marc Cory , an agent of the Solar System ' s Space Security Service discovered them and recorded a warning before his extermination by Daleks . ( TV : " Mission to the Unknown " ) About six months later , the seventh conference took place , which added the traitorous human Mavic Chen , the supposed Guardian of the Solar System , to the Alliance in order to obtain the taranium core needed to complete the Time Destructor they would use to take over the galaxy . Zephon and Celation took the places of Sentreal and Warrien . Chen acted as the informal leader , along with the Black Dalek . The Daleks requested a time machine to be sent from Skaro to pursue the First Doctor and retrieve the taranium core after its theft , the Doctor and others having overpowered Zephon and the Doctor disguising himself as him . Afterwards , the Daleks held Zephon accountable and executed him . When the fake core was retrieved and placed in the Time Destructor , Chen and Malpha were complicit in the Daleks ' plan to test it on Trantis , being wary of his power as leader of the largest of the Outer Galaxies . Though the Destructor failed , the Daleks then executed him anyway . At the final conference involving the six surviving delegates of the Galactic Council , Mavic Chen tried to take over the Council . The delegates attacked Chen , but Chen shot and killed Gearon . The alliance then ended when Mavic Chen and the Daleks turned against each other . The Dalek Supreme left the delegates fighting amongst themselves and ordered them to be imprisoned in the headquarters , planning to destroy the headquarters with them inside . As the others attacked Chen , he shot and killed Gearon before they realised they had been betrayed . However , Sara Kingdom and Steven Taylor freed Chen , Malpha , Beaus and Celation , and they agreed to form a new alliance to stop the Daleks . Three of the delegates escaped but Chen stayed behind to try to renegotiate with the Daleks , faking his death by destroying his ship and taking Sara and Steven prisoner . Losing patience , the Daleks quickly exterminated him . The Doctor then stole the Time Destructor and by operating it destroyed the Daleks by reversing time on the planet . ( TV : " The Daleks ' Master Plan " ) This event started the Great War ( PROSE : " The Evil of the Daleks " ) After Daleks destroyed Oceanus Pacifika , the Galactic Council organised the Aquarius Condition , which allowed the surviving Spaeron of Oceanus Pacifika to relocate to Earth ' s oceans . When the Spaeron melted Earth ' s polar ice caps to flood the planet , the Council revoked the Aquarius Condition and sent in a team led by Harris to wipe out the Spaeron . ( COMIC : " The Aquarius Condition " ) Later history . When the bounty hunter , Ahab , travelled back in time from the year 50000 to 2050 , he claimed he was sent to bring K9 to stand trial to the Galactic Council for the murder of Zanthus Pia , head of the Galactic Peace Commission , when infact he wanted to capture K9 because he knew that he actually murdered Zanthus .
