The 2006 series finale "Army of Ghosts"/"Doomsday" saw another squad of Dalek survivors from the old Empire, known as the Cult of Skaro, led by a black Dalek named "Dalek Sec", that had survived the Time War by escaping into the Void between dimensions. They emerged, along with a Time Lord prison containing millions of Daleks, at Canary Wharf due to the actions of the Torchwood Institute and Cybermen from a parallel world, leading to a Cyberman-Dalek clash in London. Eventually, the Tenth Doctor caused both factions to be sucked back into the Void. However, the Cult members (Sec, Caan, Jast, and Thay; it is unusual for a Dalek to have a name) survived by "temporal shifting" away. The two-part story "Daleks in Manhattan"/"Evolution of the Daleks" revealed they had escaped to 1930 New York, setting up base in the Empire State Building, which was being built at the time. Experiments led by Sec attepted to force a Dalek evolution by combining their DNA with that of humans, and he is the first of the new "Human-Daleks". However the three remaining Daleks rebelled and destroyed him because he was not a pure dalek. The Cult also attempted to create a Human/Dalek hybrid (fully human in appearance but with Dalek minds). This attempt failed after the Doctor interfered. Caan escaped via another temporal shift.
