 A Dalek force , led by their creator Davros and the red Supreme Dalek , quickly subjugate Earth , despite humanity 's fierce resistance . Military bases , including UNIT 's headquarters in New York City and their aircraft carrier Valiant , are destroyed . Davros , who was thought to have perished during the Time War , was saved by Dalek Caan , who entered the conflict after performing an emergency temporal shift . The power needed to enter the Time War — which is " time @-@ locked " , preventing time @-@ travellers from entering the conflict — caused Caan to become precognitive at the cost of his sanity .
