Golden Throne - Imperial Webway Project: The core of the device that would become the Golden Throne, whose exact origin during the Dark Age of Technology is currently unknown, was discovered by the Emperor sometime in the 30th Millennium during the Unification Wars on Terra, buried deep in sunken ruins under a huge and inhospitable desert on the continent of Asia.This was in the time before the construction of the Imperial Palace complex in the Himalazian (Himalayan) Mountains, although the exact date is also unknown. Another similar device likely used to test the technologies implemented in the Golden Throne, known as Dark Glass, was also discovered by the Emperor during the course of the Great Crusade and He set about restoring it as well.The original use that the Emperor found for the Golden Throne (or of the core device that the Throne was later constructed around) was that it was a powerful psychic amplifier that could also serve as a portal into the Labyrinth Dimension of the Webway based on Terra.Prior to the outbreak of the Horus Heresy in the early years of the 31st Millennium, the Emperor had directed tens of thousands of Mechanicum Tech-priests and Terran labourers into modifying the Throne so it could be put into use as the nexus of His secret Imperial Webway Project.This project was intended to open up the Aeldari Webway to Mankind by establishing a portal into its galaxy-spanning network from Terra. This would provide a means of instantaneous interstellar travel between the worlds of the newborn Imperium of Man, making navigation through the dangers of the Warp unnecessary and literally connecting all the worlds of Humanity instantaneously. This would create a truly unified Human race as never before in history. The Emperor believed that this level of unity would be necessary if Humanity was truly to thrive and prosper in such a dangerous universe.Additionally, the ability to travel and communicate across the galaxy using the Webway instead of the Warp would allow Humanity to dispose entirely of the need for psykers, including Navigators and astropaths. Humanity would no longer face the dangers of Warp entities and perilous travel through the Immaterium.The Human population of the Imperium could then be treated with the devices that the Emperor was building called Occullum Test Stations. These would identify the latent psychic genes in the populace, allowing the Emperor's advanced genetic science to remove the psyker mutation and eliminate psychic powers entirely from Mankind.Alternatively, if Humanity did continue to evolve into a fully-psychic species like the Aeldari, it could do so safe within the confines of the Webway, which was psychically shielded from all access by the entities of the Immaterium.Either way, this outcome would end forever the possibility of Daemonic possession of weak-willed psykers and dramatically reduce the ability of Chaos to corrupt its Human pawns. The Emperor believed that the Golden Throne and the Webway that it unlocked offered His species its best chance to free itself forever from the dangers of the Ruinous Powers.Once installed beneath the Imperial Palace in the Emperor's main laboratory called the Imperial Dungeon, the Golden Throne took the form of a bulky machine-like chair suspended over gigantic mechanised doors made of a golden alloy that served as the portal into the Imperial Webway extension. The doors were said to be large enough for a Warhound-class Scout Titan to walk through unbowed.The chair was linked to the portal by massive bundles of cables, wires and conduits. The whole contraption was made of the same golden metal and the throne was built at one end of a vast hall big enough to house five to six full companies of Space Marines. Even after the Golden Throne's construction, the lab remained littered with other machines of unknown provenance and storage crates.Hundreds of red-robed Mechanicum technicians and tithed labourers belonging to the Adnector Concillium worked in the dungeon. According to Pieter Achelieux, the Golden Throne would have required an extremely powerful psyker to operate and he implied that one of the primarchs may have originally been created to serve this role once the mechanism was in place so that the Emperor could attend to the duties of running the Imperium.The Emperor's deep disappointment with Magnus the Red's betrayal during the Horus Heresy and his inability to grasp the true dangers of dealing with the entities of the Warp suggests that the Thousand Sons primarch had been intended by the Emperor to sit upon the throne in His place.The armies of Mechanicum Tech-priests and common labourers sent through the portal below the Golden Throne and into the Imperial Webway had constructed a new extension of the network linking Terra to the rest of the abandoned Aeldari labyrinth. Since the original Webway had been constructed using a psychically resistant material which the Humans could not replicate, the Emperor used His own psychic powers, projected and amplified through the Golden Throne, to protect the Human-built extension of the Webway from Daemonic incursions from the Warp.Because of the sensitive nature of the project, the threat it presented to Chaos and fears of how the politically powerful Navigators of the Navis Nobilite might react when their monopoly on interstellar travel was rendered obsolete, the Emperor kept the construction of the Golden Throne and the Imperial Webway a secret from everyone. This included even His own gene-sons, the primarchs, and His Regent, Malcador the Sigillite.
