New Dalek Empire

"Welcome to my new empire, Doctor"

- Davros.

The New Dalek Empire was a recreation of the old Dalek Empire, which was destroyed during the Last Great Time War.

Overview
The New Dalek Empire was somewhat different compared to the Dalek forces that appeared after their empires supposed destruction in the Time War. They were not survivors using scattered technology but rather a true empire and quite capable of combating Time Lord technology. They were even capable of capturing and disabling a TARDIS. Their forces consisted of hundreds of starships with enough forces to devastate the universe. Their central base of operations was the Crucible where they planned to reside on when the reality bomb destroyed the universe.

First attempts
"We had to survive!"

- Dalek Sec

The New Dalek Empire was to be the new Empire of the Daleks that the Cult of Skaro had planned to create. The very first attempt was on planet earth with the Genesis Ark, to unlock it and unleash the Daleks within, of which the doctor thwarted. Time traveling from London in 2007 to New York City in 1930, the Cult, now the last four Daleks in existence, attempted to conquer Earth and recreate the Dalek Empire.

This attempt, even with the help of the Final Experiment (which included use of Pig Slaves and Human-Dalek hybrids) failed due to the interference of the Doctor. At the end, Dalek Caan was the last surviving Dalek. (DW: Daleks in Manhattan / Evolution of the Daleks)

New Empire
"We will be the only lifeforms in existence!"

- Supreme Dalek

Caan activated an emergency temporal shift to escape the Doctor, and ended up at the Gate of Elysium during the Last Great Time War. Travelling into a time-locked era ruined his mind, but he helped to save Davros from his death. Davros, like the Dalek Emperor who also surivived the Time War by time travel, rebuilt the Dalek Fleet of two thousand ships and millions of Daleks - unlike the Emperor, Davros rebuilt the Daleks out of his own Kaled cells. Caan was left as a sort of prophet, and a new Dalek Supreme was created to oversee the Dalek forces.

The Daleks moved 27 planets into the Medusa Cascade from various times and places (mostly mid-2009, but from other eras as well). These made a large device when put together. The new Daleks then took control over the planets in the Cascade, apparently concentrating their forces on Earth. They took many Humans on board their ships, and wiped out any resistance. (DW: The Stolen Earth)

The new Empire planned to use the 27 planets in the Medusa Cascade in conjunction with the Crucible's energy source to power a Reality bomb created by Davros. This would have led to the destruction of all of existence and allow the Daleks to be the sole inhabitants of the universe. However, interference from the Doctor and his companion Donna Noble led to the device being destroyed. Despite this, the Daleks had enough warriors and starships to leave a large swathe of the universe aflame until they were killed by the New Doctor overloading and feeding back the Daleks' Dalekanium. Also, Dalek Caan was in fact working against them and aiding the Doctor, having deemed the entire race evil after seeing what they had done. This act destroyed all the Daleks and their starships which includes the Crucible. Its presumed that the Dalek race were destroyed as a result of this act, although as Caan, Davros and the Emperor were not affected, theoretically there could have been others immune to the effect as well.
