Imperial Palace - History: During the turbulent era known as the Age of Strife, the Sol System and the nearby star systems that had been colonised by Humanity during the Age of Technology were effectively cut off from interstellar travel or communication with each other.This was due to the massive Warp Storms that swept the galaxy as the Immaterium was roiled by the millennia-long gestation of the Chaos God Slaanesh and the turbulence that marked the decay of the Aeldari Empire before the Fall.During this long, 5,000-year-period of anarchy, fear and violence, Old Earth's once unified planetary government had completely broken down and been divided into dozens of warring states of so-called "techno-barbarians."Continuous warfare raged across the surface of Terra for 2,500 standard years, beginning in the late 27th Millennium. Little remained of the once sophisticated civilisation of Old Earth's glorious past as the centre of a growing Human interstellar civilisation marked by advanced science, high culture and wondrous technologies.This was a dark period for the people of Old Earth, when they were dominated by brutal rulers and despotic tyrants. It was against this backdrop of oppression, violence and casual brutality that the Emperor of Mankind first revealed Himself to the people of Terra.In secret, He had been planning for this moment in history for millennia, ever since the Age of Strife had fractured what remained of the ancient Human interstellar civilisation.With His massive army of genetically-enhanced warriors, comprised of the first units of the Imperial Army that would serve as the prototypes for the later development of the Space Marines, the Emperor began His conquest of Terra.His intent was to reunite the warring nations into a unified planetary government and then use Terra as the springboard from which to begin His reconquest of the galaxy under the aegis of an Imperium of Man dedicated to the Imperial Truth of progress and reason.Once Unity was nearly achieved as the Unification Wars wound down in the late 30th Millennium, the artisan masters of the many rival Masonic Guilds raised the Emperor's Imperial Palace up, block by gilded block, to be a statement of Unity, regal and unequivocal. The warring tribes and creeds of Terra had been alloyed under one rule, and the Imperial Palace was intended to symbolise that staggering achievement.The Imperial Palace is not so much an edifice as it is a handcrafted landmass. The artisan masters built it upon Terra's greatest mountain range, the Himalazia (Himalayan) Mountains, and transformed the monstrous peaks into its bulwarks.It towered above a world laid to waste by centuries of war and perdition, and though that world was being rebuilt, with wondrous cities and architectural marvels blooming in the new age of Unity, nothing could match its magnificence.For it was beautiful, a euphoric vision of gold and silver. It was said that, when they had finished their task, the artisan masters of the Masonic Guilds set down their tools and wept.By the time it was completed, it was the largest single man-made structure in known space. Its footings sank deep into the planet's mantle, its towers probed the airless limits of the atmosphere.This massive structure is today an interconnected series of continent-wide fortifications comprised of cyclopean and pyramidal structures that extend for several kilometres into the sky and for several dozen kilometres beneath the surface of Terra. The Palace is said to have 4,029,854 chambers in its entirety.
