Dalek Time Strategist (The Shadow Vortex)

A Dalek Time Strategist was a major player in the Last Great Time War.

Origin
Following its defection from the Dalek Empire, the Dalek Time Controller's consciousness became part of the Eminence. Shortly afterwards, the Dalek Supreme commissioned the creation of the Dalek Time Strategist from the remains of the Dalek duplicate Adelaine Dutemps. (AUDIO: Eye of Darkness)

The Last Great Time War
The Dalek Time Strategist became a major player in the Last Great Time War. Two months into the War, it informed the Dalek Emperor that there was a secret Time Lord base in a pocket dimension which was vital to Project Revenant. The Emperor approved its strategy to seize the facility. After the base was destroyed by the CIA, eliminating the Dalek invasion force as the pocket dimension collapsed, the Emperor ordered it to devise a new strategy. (AUDIO: Desperate Measures)

Stopping the Master
After the Master used the Anti-Genesis codes to completely rewrite Dalek history, (AUDIO: From the Flames, The Master’s Dalek Plan) the Strategist commanded a single Dalek timeship, the only remnant of the original Daleks. It rescued the Master of a parallel universe and ordered him to help the Daleks stop his counterpart. The parallel Master attempted to find the progenitor of the disturbances, but every suspect proved incorrect and the Daleks’ resources were diminishing with each attempt. (AUDIO: Shockwave) Instead the Strategist and the parallel Master targeted the Master himself, stocking his paranoia that his Daleks would turn on him. The Master was eventually convinced and helped them find his past self prior to altering Dalek history. The Masters attempted to convince the younger Master to abort his plan whilst the Strategist exterminated his assistant Crazlus, who was vital to the Master’s Anti-Genesis plan, restoring the timeline to normal. The Strategist ordered the restored Daleks to capture the fleeing Master. (AUDIO: He Who Wins)

Restoring the Daleks
The Dalek Time Strategist was present on Grahv when the Daleks had created a new super weapon to erase the Time Lords from existence. The Time Lords sent the Valeyard to Grahv and he managed to turn the weapon against the Daleks, erasing them from existence instead. The Time Strategist swore to the Valeyard that "this [was] not the end" and escaped through a dimensional portal, (AUDIO: The War Valeyard) emerging from a similar dimensional portal created by an alternate universe Davros on a parallel Skaro. After convincing Davros that the Eighth Doctor, whom Davros had previously encountered via the same portal, intended to eradicate the Kaleds of Davros's universe, the Dalek Time Strategist ordered Davros to wire his dimensional portal into the Time Strategist's mutant body, combining their expertise on time, space and the multiverse to merge echoes of Davros's selves from across the multiverse together, using the Davros of this Skaro as the template. The Time Strategist extended this merging to include echoes of the different Daleks created by Davros's alternate selves, (AUDIO: Palindrome) so that by the time they returned to N-Space via the Gulf of Ithon, the Daleks were infinite in number, allowing the Last Great Time War to begin again.

After travelling to Koska to harvest data from Davros to complete the restoration of the Daleks, the Dalek Time Strategist travelled with the Eighth Doctor to the Time Strategist's enclave between universes. The Dalek Time Strategist explained to the Doctor that, despite scouring every universe, he could not locate the original Dalek Emperor, and so decided to complete the Daleks's restoration by resurrecting the Emperor of N-Space instead. When questioned by the Doctor, the Time Strategist explained that he had kept the Time Lord alive due to his complex involvements with the Daleks' timeline; having seen the Doctor's future, the Time Strategist attempted to persuade the Doctor to destroy Gallifrey by offering him a cryo pod containing an alternate universe version of his great-grandson, Alex Campbell, (AUDIO: Restoration of the Daleks) whose N-Space equivalent had been killed previously by the Daleks. (AUDIO: To the Death) Despite the Time Strategist's advice, the Dalek Emperor ordered the Daleks to capture Davros from Koska to execute him directly; when Davros triggered a civil conflict between the Daleks concerning who should lead the restored Dalek Empire, between Davros and the Emperor, the Dalek Time Strategist desperately attempted to stabilise the Emperor when Davros's actions terminated the Time Strategist's multiverse matrix. As the Time Strategist lost its infinite Dalek reinforcements, it frantically performed an emergency temporal displacement as its enclave was destroyed by an isomorphic bomb brought to the enclave by Major Tamasan. (AUDIO: Restoration of the Daleks)

Opposing the War Doctor
Later in the Time War, the Dalek Time Strategist sent Lara Zannis to Earth to capture the Shadow Vortex. The Time Strategist wanted to invade the Earth in order to destroy it and stop the Doctor from meeting his companions, hopefully erasing him from history. (AUDIO: The Shadow Vortex)

Later, the Dalek Time Strategist sent the Daleks to Rovidia to capture Cardinal Ollistra, intending to steal her knowledge of Time Lord secrets. The Sontaran General Fesk tricked the Time Strategist into meeting him and took the Time Strategist prisoner, disarming it. The Time Strategist was placed with Ollistra where they talked about the starting of the Time War. In the chaos caused by the rescue attempt of Ollistra by the War Doctor, Heleyna and Kalan, the Dalek Time Strategist was recovered by the Daleks. (AUDIO: The Eternity Cage)

The Dalek Time Strategist ordered the destruction of the Rovidian fleet after the Doctor left the planet. The Time Strategist believed that the Doctor had given the Daleks the means to win the Time War. It used Heleyna to gain access to the Eye of Harmony chamber within Vassarian's Battle TARDIS and planned to use the Dalek Time Squad to attack the Eye and cause it to collapse to destroy the Time Lords. The Doctor stopped the Time Strategist's plan by destroying the Eye of Harmony Chamber. After the Battle TARDIS disappeared from the Time Vortex the Dalek Time Strategist ordered that all the timelines be scoured to find the Doctor and destroy him. (AUDIO: Eye of Harmony)

The Dalek Time Strategist ordered the destruction of the space station the Doctor had landed on as a way to kill him. Later, after he had saw Schandel's news report on the Doctor he ordered the complete destruction of Beltox. (AUDIO: Pretty Lies)

Learning that the Doctor had gone to Grend, the Dalek Time Strategist ordered the Dalek fleet to go there regardless of the threat at the Obsidian Nebula. It later ordered the destruction of Rosata Traxter's ship in order to destroy the Doctor. When this failed the Time Strategist ordered the search of the Obsidian Nebula for the Doctor. After one of the Dalek Hunter Drones disappeared, the Time Strategist went into the nebula, where Skaul gave him an ultimatum; the Time Strategist decided to give him the coordinates of where they were heading as the Daleks had to go back to the Battle at Grend. When it realised that the Time Lords weren't originally supposed to be there, the Time Strategist ordered them to leave as its prime objective was now ready. (AUDIO: The Lady of Obsidian)

The Dalek Time Strategist went to a dimensional sphere to start its final plan. It had sent the Enigma to Gallifrey to destroy the Time Lords. When the Doctor took his TARDIS to the same dimension as him, the Time Strategist thought that doing so wasn't possible. He had threatened the Enigma to do his work. When the Daleks' powered up their weapon to destroy the Enigma, the Time Strategist realised that the TARDIS was absorbing energy from it. (AUDIO: The Enigma Dimension)

Appearance
The Dalek Time Strategist active during the Time War possessed a purple casing similar to the red Supreme Dalek of the New Dalek Empire (TV: The Stolen Earth / Journey's End) and the Supreme Dalek who controlled the Dalek City. (TV: The Magician's Apprentice / The Witch's Familiar) Unlike them, but like the Dalek Time Controller, its casing housed a Time Controller device and it developed a smooth purring voice.
