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 Time Strategist was present on Grahv where a new superweapon had been created. The Time Lords sent the Valeyard to Grahv and he managed to turn the weapon against the Daleks, erasing them from existence. The Strategist swore to him that this was not the end and escaped through a rift. (AUDIO: The War Valeyard)

Opposing the War Doctor
Later in the War, it 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 the timelines. (AUDIO: The Shadow Vortex)

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

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

The 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 he ordered the 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 it ordered the search of the Obsidian Nebula for the Doctor. After one of the Dalek Scout drones disappeared, he went into the nebula. 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, it ordered them to leave as its prime objective was now ready. (AUDIO: The Lady of Obsidian)

It went to a dimensional sphere to start his 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 he thought it wasn't possible. He had threatened the Enigma to do his work. When the Daleks' powered up their weapon to destroy the Enigma, it 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. (AUDIO: Eye of Harmony)
