Mars - Notable Locationse: High Altar of Technology - Within the Temple of All Knowledge is the High Altar of Technology -- a vast database containing the knowledge of the Tech-priests. Even today every new discovery is dedicated to this altar. Every temple on Mars and throughout the other Forge Worlds is connected to the High Altar by means of a living Transmat link, a psychic Servitor whose mind co-joins all altars of the Cult Mechanicus into one holy machine entity.Librarius Omnis - The Librarius Omnis is a vast subterranean, continent-spanning repository of knowledge located in the labyrinthine catacombs of Mars. Over the millennia, it has been the subject of several Techno-archaeologist expeditions. It was here, at the dawn of the Imperium, that the legendary Techno-Archaelogist Arkhan Land led an expedition with the intention of finding an intact, complete and still-functioning STC database. Though he was unsuccessful in this endeavour, he did make two other discoveries which revolutionised Imperial technical thinking for millennia to come -- a near complete dataslab image of STC information on what would come to be known as a Land Raider, and information on rare anti-gravitic plates, and theories on their uses, which eventually led to the construction of the first "Land Speeder."Libarium Omnissiah - The Librarium Omnissiah is a large repository of knowledge said to contain large, mile-long logi-stacks which contains records of thousands of mysteries of the universe. It is said to rival even the archive-catacombs of the Adeptus Terra.Mondus Occulam - Mondus Occulam was a powerful Forge Temple located in the Tharsis region of Mars. At the dawn of the 31st Millennium, it was one of the largest and most productive Forge Temples on Mars, surpassed by only Olympus Mons in size. Like many forges at the time, it was geared for war production -- exclusively manufacturing arms, equipment and Power Armour for the Legiones Astartes spread across the galaxy during the Great Crusade. As a result of their size and productivity output, Forge Master Zagreus Kane was made Fabricator Locum, the second highest-ranking individual of the Mechanicum, responsible for assisting the Fabricator-General with the governance of Mars. This particular forge was also responsible for the training of Space Marine Legionaries to become Techmarines. Only Mondus Gamma forge, under the mastery of Lukas Chrom, could replicate the quality of training offered by Mondus Occulam, but they could not match Mondus Occulam for the sheer quantity of well-trained Techmarines coming out of their forge. Following the outbreak of hostilities between the Dark Mechanicum and those Tech-priests still loyal to the Throneworld during the Schism of Mars, Mondus Occulam was one of the few forges that escaped total collapse when Chaotic scrapcode was unleashed throughout Mars' communication networks. Elements of the Imperial Fists, under the commander of First Captain Sigismund, managed to make planetfall and secure the forge's armour and weapons supplies. Despite the protestations of Fabricator Locum Kane to save his forge, Sigismund ordered the evacuation of Mondus Occulam when over sixty Traitor Titans launched an overwhelming assault on the forge.Noctis Labyrinth - The Noctis Labyrinth is a region of Mars that lies between the Valles Marineris and the Tharsis Uplands. In Low Gothic, the name translates as "Labyrinth of the Night." It is here, deep beneath the Noctis Labyrinthus, that the fearful entity, known only as the Dragon of Mars in Mechanicus legend, sleeps for eternity. This being may be the C'tan known as Mag'ladroth the Void Dragon, who was imprisoned there by the man who became the Emperor of Mankind millennia prior to the dawning of the Age of Strife and is watched over by a single guardian, a Terran girl named Dalia Cythera, who has guarded it since the Schism of Mars during the Horus Heresy. It would be another 10,000 standard years before a new guardian would be drawn to the Noctis Labyrinth to take Dalia's place.Olympus Mons - Known also as the "Grand Mountain" to the Titan Legions of Mars, Olympus Mons is the largest mountain on the Red Planet and is the site of the largest and most productive Forge Temple. This is the seat of the ruling Fabricator-General of Mars. It is also here that the largest structure on Mars -- the all-important Temple of All Knowledge -- lies within the massive city.Ring of Iron - The Ring of Iron is the name given to the massive, ring-like orbital constructions that turn above the Martian equator. Spacecraft and other large starfaring constructs are constructed within the Ring's extensive orbital factories, and many of the starships of the Battlefleet Solar are based in its huge floating docks.Temple of All Knowledge - The Temple of All Knowledge is the holiest place on all of Mars. Within the temple's plasteel shell, shining pistons hold the vaulted roof almost a Terran mile above. The shafts of each prism are so constructed that they move to raise and lower the roof, altering its acoustic properties to accentuate the hymns of praise sung to the Machine God. Within is the High Altar of Technology, the vast database containing all knowledge of the Tech-priests of Mars. Despite the massive Warp rift known as the Great Rift dividing the Imperium in two since 999.M41, the Temple of High Knowledge still receives messages daily which are down-loaded into the High Altar -- fleeting reports from the other Forge Worlds across the galaxy, data from recovered machines, confirmations of new discoveries, or desperate pleas for help.Tharsis - Tharsis is the region of Mars that surrounds the capital at Olympus Mons. During the early years of the 31st Millennium, it was one of the most productive and abundant on all of Mars and was home to a number of powerful Forge Temples. By the late 41st Millennium, holding mastery of a Tharsis-based forge was still considered a valuable position for a member of the Cult Mechanicus.Vaults of Moravec - The Vaults of Moravec were a depository of forbidden knowledge and techno-arcana founded by Primus Moravec of the Brotherhood of Singularitarianism, who sought to hasten the creation of a technological singularity which would create an artificial general intelligence greater than Human intelligence. Located on the Mechanicum's holy world of Mars in the Segmentum Solar, it was hidden in a sealed vault inside a maze of old tunnels and chambers nearly a kilometre deep beneath Olympus Mons -- the mighty forge of Fabricator-General Kelbor-Hal. The Vaults of Moravec had been deliberately kept locked by the Emperor of Mankind who correctly judged the knowledge it contained as too dangerous to be known publicly. When the Warmaster Horus Lupercal began to plot his rebellion against his father, he promised Kelbor-Hal to lift the Emperor's ban on the forbidden knowledge stored there, thus swaying this powerful figure to his service. The opening of the Vaults of Moravec would spark the civil war inside the Mechanicum that would become known as the Schism of Mars and mark the true birth of the Dark Mechanicum.
