( AUDIO : " Intervention Earth " ) During the final times of the Last Great Time War , Rassilon sent a group of agents of the CIA along with Karlax , who had the mission to kill the War Doctor because of his opposition to the plans of the High Council .

They were halted by the people of the Catuvalani . The Eighth Doctor escaped with the Type 102 TARDIS . ( PROSE : " The Shadows of Avalon " ) At some point in the lead - up to the War , the CIA became worried that they might be erased from history ( or caught in the crossfire ) between the Time Lords and the enemy , and therefore created Mictlan , a world outside of time and the universe for themselves to hide within .
