The Golden City Zone, (COMIC: "Part Fourteen: The Nightmare Ends" [+]Part of Liberation of the Daleks, Alan Barnes, DWM Comics (Panini Comics, 2022-2023).) known to its inhabitants as simply the Universe, (COMIC: Part Nine: Deep in Hyperspace [+]Alan Barnes, DWM Comics (Panini Comics, 2022-2023).) was one of the psychoscapes within the Dalek Dome. Based on tabloid reports about the early Daleks from "21st century children's books", (COMIC: Part Twelve: The Garden of Death [+]Alan Barnes, DWM Comics (Panini Comics, 2022-2023).) it included a version of Skaro, complete with the Dalek City, located "deep in Hyperspace". Ruled by a duplicate Golden Emperor, these Daleks were "the most terrifying creatures in existence" to the inhabitants of their universe.
The Emperor learned of his universe's true nature when Georgy Gold, a fellow psychoplasmic construct who had gained awareness of her true nature and discovered she would destabilise if she remained in the "real" universe for too long, teleported into the Golden City Zone to save herself. Questioned by a Dalek interrogator, she convinced it of the reality of the alternative Daleks and persuaded it to inform the Emperor. (COMIC: "Part Nine: Deep in Hyperspace" [+]Part of Liberation of the Daleks, Alan Barnes, DWM Comics (Panini Comics, 2022-2023).) The Golden Emperor used the Brain Machine to conduct a "sub-atomic analysis" of all Daleks in the City. Realising that they were too identical in molecular structure to be real, the Brain Machine confirmed to the Emperor that his universe was artificial. Though his mind nearly broke from the revelation, the Emperor, having learned that it was theoretically possible to stabilise psychoplasmic constructs in real-space using extremely complex calculations, decided to stage an escape from his psychoscape and invade the outer universe. (COMIC: "Part Ten: Golden Age" [+]Part of Liberation of the Daleks, Alan Barnes, DWM Comics (Panini Comics, 2022-2023).)
Having made a deal with Georgy, they had her telepathically communicate with her template in the real world, Georgette, to broadcast a telepathic pulse to take control of all humans in the Dalek Dome. The Emperor had them alter the parametres of his psychoscape to spontaneously generate a new moon for Skaro, populated by Multiplying Mathematicians who would mentally calculate the incredibly complicated algebra necessary to generate a Reality Gate allowing psychoplasmic Daleks to safely make the jump to the Doctor's universe. (COMIC: "Part Eleven: Slave to the Rhythm!" [+]Part of Liberation of the Daleks, Alan Barnes, DWM Comics (Panini Comics, 2022-2023).) Realising that he would need more raw psychoplasm to increase the number of his army, the Emperor decided to drain the other Zones within the Dome of psychoplasm. The Fourteenth Doctor, who had stumbled into the middle of the crisis, escaped from the Golden City Zone and brought these news to the Type I Dalek Emperor's psychoscape, convincing the Emperor to help subdue his counterpart, (COMIC: "Part Twelve: The Garden of Death" [+]Part of Liberation of the Daleks, Alan Barnes, DWM Comics (Panini Comics, 2022-2023).) ultimately forming a Dalek Alliance with the Dalek leaders of multiple other Zones. (COMIC: "Part Thirteen: The Hell Gate!" [+]Part of Liberation of the Daleks, Alan Barnes, DWM Comics (Panini Comics, 2022-2023).) Ultimately, the Doctor redirected the Golden Emperor's flagship to crash into the Mathematicians' Moon, destroying the Emperor, the Mathematicians, and, with them, the Reality Gate — with the effect of melting down all the Daleks who'd already crossed out of the Golden City Zone. The Zones themselves, however, were left standing, with the Doctor leaving their fate up to Georgette.
