The Dalek Dome was an exhibition on Earth which displayed all the most important moments in the history of the Daleks spread out and divided into zones. The building had a resemblance to the upper section of a Dalek casing, and in the centre of the Dome was a lift to the Skaro Observatory, which was a giant Dalek eyestalk with a view of the planet Skaro.
What would become the Dalek Dome was originally a cloned safari before laws were passed to ban such a practice. To keep their jobs, the staff genetically engineered themselves to have animal attributes and become the new exhibits only for the first alien zoo to cause business to plummet and the site to be sold to the military. The military later discovered a crashed Dalek flying saucer on an alien planet, harvesting twelve surviving Kaled mutants.
The mutants were placed in psychoplasm liquid, their dreams being used to fuel quantum simulations. Known zones were: the Jungles of Spiridon Zone, the Skaro Civil War Zone, the Vulcan Factory Zone, the Death Wheel Zone, the Earth Invasion Zone, and the Zeg Duel Zone. Visitors to the Dome included Captain Kirk, Mr Spock, Astrans and Raxacoricofallapatorians.
In 2323, Lieutenant Georgette Gold discovered records of the Doctor in her Dalek Studies, using the space-time telegraph to get his attention, hoping he could help with her PhD. When the Fourteenth Doctor arrived, he materialised in the 1966 Dalek invasion of Earth. Unaware that it was a false invasion, the Doctor drew the attention of the Daleks and discovered their nature as fakes, rousing the consciousness of Specimen Six Sigma, the mutant who fuelled the Zone. The Doctor was extracted by the staff and shown the Dome, disgusting him at how the suffering of billions had been exploited and commercialised. Managing to board the Doctor's TARDIS when the Earth Invasion Zone was reset, the false Supreme Dalek managed to briefly enter the Dalek Dome only to collapse into psychoplasm. Fearing that the same fate would soon befall her, Georgy Gold, a psychoplasm construct based on Georgette who had also been in the TARDIS, fled into the Golden City Zone.
Taken prisoner by the Daleks who lived there, Georgy managed to convince them of their true nature as simulacra, hoping that they could take control of the dome to save all the psychoscapes. Pretending to agree, the Golden Emperor exploited Georgy's link to Georgette to summon the Doctor to him and to beam a hypnotic signal to take control of the Dome. With hostages, the Emperor demanded the Doctor to explain how to stabilise them in the real world. With a scoff, The Doctor stated that a quantum-powered reality gate would be needed, but even then, the process would take millennia without innumerable elite mathematicians to do the work. Satisfied, the Emperor ordered the psychoscape controllers in the Dome to expand their simulation, creating the Mathematicians' Moon whose population of Quadruple-Brained Algebraists quickly completed the calculations needed for a reality gate.
Though the Doctor managed to convince Georgy of the evil of the Daleks, she was quickly exterminated following her breaking the Dalek interrogator's eyestalk. Undeterred, as he still controlled the Dome's Informational Dalek machines, the Emperor ordered the other Dalek Zones drained of psychoplasm to allow the full might of his Dalek Fleet to enter reality. When Georgette's group came to rescue the Doctor, he teleported them to the another Zone, proposing an alliance with the Old Skaro Emperor to stop the Golden Emperor.
Following a Dalek Scout Craft confirming that the reality gate was stable, the Golden Emperor launched his fleet, starting the 2323 Dalek invasion of Earth. The Old Skaro Emperor meanwhile constructed a squad of Short-Range Teleport Daleks sending to invade the Golden City Zone. Finding this insufficient, the Doctor arranged for a link to be set up with the Dalek leaders of the other Zones, resulting in the formation of the Dalek Alliance. After the Golden City Daleks quickly exterminated the Teleport Daleks, the full Dalek Alliance invaded the Golden City while the Old Skaro Emperor covertly sent a battalion of Death Squad Daleks through the reality gate to exterminate all the other mutants save his own true self.
Finding the battle lost, the Golden Emperor sought to flee to Earth only for the Doctor to board his escape rocket, sabotaging its navigation and sending it on a collision course with the Mathematicians' Moon. The Golden Emperor promptly destroyed the Doctor's sonic screwdriver, promising only to release the Doctor's TARDIS if he was given safe passage aboard. Though the Doctor agreed, the Golden Emperor belatedly realised that his casing was too wide to fit through the doors. When the rocket crashed into the moon, the reality gate collapsed, collapsing all the Daleks who had crossed over into reality.
In the aftermath, the Doctor left the future of the Dalek Dome in the hands of Georgette Gold, whom he pointed out had now seen the true evil of the Daleks up close. Upon entering his TARDIS however, he saw that the false Jules Rimet Trophy had also melted into psychoplasm, hoping that the liquid hadn't affected the fast return switch.
