Emperor of the Restoration

The Emperor of the Restoration was the Dalek Emperor who founded the Restoration Empire from the ashes of the Imperial Dalek faction following the close of the Imperial-Renegade Dalek Civil War. He wore a golden casing with a large bulbous dome, deliberately harkening back to the Emperor of the bountiful, unified pre-Civil War Dalek Empire. (PROSE: The Restoration Empire)

According to some accounts, the new Dalek Emperor of the Imperial Daleks then led his people into a time war against Gallifrey, becoming the Dalek Emperor in the Last Great Time War. (PROSE: Dalek: The Astounding Untold History of the Greatest Enemies of the Universe) According to other accounts, however, the Dalek Emperor who led the Dalek Empire following the Civil War, and onwards throughout the Time War, was instead the Dalek Prime himself, who had, in the Civil War, been the ultimate leader of the Renegade Daleks. (AUDIO: Restoration of the Daleks)

Rise from Supreme to Emperor
During the Imperial-Renegade Dalek Civil War (PROSE: The Restoration Empire, TV: Remembrance of the Daleks) the Dalek Supreme who would later become the new Dalek Emperor served on the Dalek Council. After Davros fled the war, he exterminated all other members of the council and appointed himself the new Dalek Emperor. Modelling himself on a former emperor, he built himself a gold casing and augmented his brain capacity.

The Restoration Empire
From this position, he sought to restore the Dalek Empire to its former glory through a new hierarchy of Dalek command and a new system of production. He restored Skaro (PROSE: The Restoration Empire) after it was destroyed by the Seventh Doctor (TV: Remembrance of the Daleks) and overhauled the standard Dalek hierarchy, bringing back Silver Daleks as drones (PROSE: The Restoration Empire) instead of the white-and-gold livery favoured by Davros's Empire. (TV: Remembrance of the Daleks) Also among the Emperor's forces was the Dalek Prime Strategist, a unit who claimed to be older than the Emperor. (COMIC: Defender of the Daleks)

Into the Last Great Time War
According to one account, the new Dalek Emperor continued with Davros's plan for the Imperial Daleks to move against the High Council of the Time Lords, thus leading his armies into the Last Great Time War. (PROSE: Dalek: The Astounding Untold History of the Greatest Enemies of the Universe) This stood in contrast to another account in which the Dalek Emperor in the Last Great Time War was the original Dalek Emperor who once led the Renegades. (AUDIO: Restoration of the Daleks) The Dalek Emperor in the Last Great Time War led his people throughout the War and eventually fell through time (TV: The Parting of the Ways) and the Void (PROSE: The Whoniverse) on the last day of the War with his command ship. He was ultimately slain by Rose Tyler as the Bad Wolf entity. (TV: The Parting of the Ways)

Shift in the timelines
When the Tenth Doctor poisoned the Kotturuh in the Dark Times, (PROSE: The Knight, The Fool and The Dead) he caused fluctuations in time, (PROSE: The Guide to the Dark Times) resulting in the Restoration Empire never fighting the Time War. (COMIC: Defender of the Daleks) The Emperor received a message from an ancient Dalek drone, which he deduced was a survivor of a Time Squad that had yet to be sent back in time. From the message, the Emperor concluded that history was under attack, which the Dalek Empire was vulnerable to, and that the Doctor was involved, but still needed more information. He decided the necessary information could be found somewhere like the Archive of Islos. (PROSE: The Last Message)

The Emperor personally led the Daleks’ invasion of Islos to seize the Archive. However, the Chief Archivian made a deal for the rescue of the Archive, promising their rescuer the Daleks. When the Emperor entered the Archive along with the Strategist and Executioner, they found it empty. The Chief Archivian informed them of its deal as an Entity emerged from a portal. (WC: The Archive of Islos) The Daleks retreated from Islos and returned to Skaro, pursued by the Entity. It attacked Skaro and the Daleks’ firepower proved ineffective, forcing the Emperor to order an evacuation. The Strategist advised that the evacuation was failing and they should abandon the planet. The realisation that the home planet had been lost caused the Emperor to fall silent, forcing the Strategist to coordinate the retreat. After the Strategist suggested reinforcements, the Emperor decreed that the Sentinel of the Fifth Galaxy was required. The Strategist was sent to meet the Sentinel and awaken a dormant army of 10,000 Daleks however the Entity compromised the army and took it over. As the Executioner led Dalek forces against the army, the Strategist advised the Emperor to withdraw again as they could not sustain further losses and defended its failure. (WC: The Sentinel of the Fifth Galaxy)

The Daleks eventually reclaimed Skaro (COMIC: Defender of the Daleks) however the invasion of the Archive of Islos had also unleashed the Hond. (PROSE: The Restoration Empire) With Skaro in danger of falling to the Hond, the Prime Strategist suggested to the Emperor that the Doctor be used against the Hond. The Tenth Doctor was captured by the Daleks and brought before the Emperor. He recognised the Empire he was interacting with, who had never fought in the Last Great Time War, as "a paradox". The Emperor convinced him to help them and sent him to meet the Strategist. Together they discovered a way to pacify the Hond, which they deployed just as they approached Skaro’s defences. Afterwards the Doctor escaped, with the aid of the Thirteenth Doctor, and the Strategist met the furious Emperor. The Strategist defended its failure and suggested the Daleks could use other Doctors, such as the Eighth Doctor. (COMIC: Defender of the Daleks)

Eventually the Emperor formed a Time Squad to rectify the temporal fluctuations to the Daleks’ benefit. (PROSE: The Guide to the Dark Times)
