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.

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, resurrected by the Dalek Time Strategist. (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 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
However, Dalek scientists began to uncover ripples in time which threatened the Restoration Empire, the invasion of the Archive of Islos was ordered, which unleashed the Hond. (PROSE: The Restoration Empire) The Tenth Doctor was captured by the Daleks to help against the Hond, having an interview with the Emperor; he recognised the Empire he was interacting with, who had never fought in the Last Great Time War, as "a paradox".
