Guidance Guidance was the Eutermesan leader of the Church of the Foundation and the father of the Eighth Doctor ' s companion C ' rizz . History . Guidance was an elder of the Church of the Foundation on Eutermes , where he taught his son C ' rizz . When the Kromon sacked the village , C ' rizz assumed he was killed . In reality , Guidance survived the incident and continued as a teacher , eventually becoming the spiritual leader of the Church . Daqar Keep then purchased the Church and used it to find the site of the original Foundation , where the religion had started . With Guidance ' s help , he found it . Not wanting the secrets of the Foundation ( in reality Rassilon ' s Foundry ) to fall into Keep ' s hands , Guidance pretended to take a long time to find the Foundation ( a fact that Keep and Perfection were aware of but unconcerned about ) . When the TARDIS crew arrived , Guidance approached his son and told him the secrets of how the Eutermesans ' personalities change to suit the people surrounding them and of how the whole universe ran in an endless cycle . Then he " purged " the supposedly blasphemous ideas that C ' rizz had picked up by half - drowning him , hoping to snap his son back into the Church ' s training . Guidance then went with C ' rizz to the Foundation , where they met up with the Doctor , Charley Pollard and Daqar ' s wife Perfection . Shortly after entering , Daqar Keep forced his own entry and murdered Guidance by creating a pair of vultures out of his body that tore Guidance ' s eyes out . He died proclaiming that all he had done was right . ( AUDIO : " The Next Life " ) Personality . The Eutermesans were physical and psychological chameleons , easily influenced — a fact that Rassilon used to his advantage in plotting his escape from the Divergent Universe . As such , Guidance was a religious zealot . In entering the Foundation he believed that he would be meeting his creators . Putting the Church above all else , he almost killed his own son when C ' rizz started thinking that the Foundation was not all Guidance claimed . He almost openly despised Daqar Keep even though ( or because ) Keep had purchased the Church with massive amounts of money . He also disliked Perfection , calling her the Doctor ' s whore on one occasion . Presumably he knew about Keep ' s powers but this only lessened his opinion of the creature , an arrogance which lead to his death . Unlike most other Eutermesans , Guidance was aware that their species ' personalities moulded to fit the people around them , yet it still never occurred to him that he was being manipulated ( by Rassilon who was the original creator of the Church ) . He also knew that the most adept Eutermesans could not only change the colour of their skin but also their texture . Being highly adept himself , he was able to camouflage himself to the point of almost being invisible , even to his son ' s eyes . ( AUDIO : " The Next Life " ) Notes . At some point in C ' rizz ' s childhood , Guidance and the other members of the Foundation turned C ' rizz into a vessel for the minds of everyone he killed . Guidance had given a moonstone pendant to C ' rizz , that matched his own . The pendants were revealed to be two halves of a key that opened the gateway between the Divergent Universe and our own universe . Rassilon stated that Guidance ' s reason for existence was to get those pendants to him at the right time . ( AUDIO : " The Next Life " )
