Fortress-Monastery - Miscellaneous Chambers: Assimularum - This is the largest room in the complex besides the great hall. It is a vast and high vaulted room, in which the entire Chapter can be gathered. It is used for mass meetings, ceremonies, religious festivals and special feasts.Guest Chambers - Relatively luxurious chambers reserved for important visitors such as members of the Imperial Administratum or the Adeptus Mechanicus.Launcher Pads - The Chapter's aircraft are housed in underground hangers beneath the launcher pads, including large transports, gunships and multiple high-speed scout vessels.Shuttle Silos - The bulk of a Chapter's fleet is located in orbit and the only vessels located within the fortress are those required to get to the fleet, mostly including couriers and transport vessels.Teleportarium - These Warp teleporter rooms are spread throughout the base in four places and are the primary means of moving between the fortress and the fleet. The Teleportarium Primus is used to receive guests. Those Chapters like the Black Templars who refuse to have any interaction with the Warp will use more mundane means like orbital shuttles to move between the planetary surface and the Chapter fleet.Company Chapel - The most commonly used place of worship. Every company has its own chapel located within its company block. This worship is part of the Space Marine brethren's regime of discipline.Reclusiam - The Reclusiam is usually partitioned from the Assimularum by a screen, and is used only for Imperial Creed or Chapter cult activities. It is looked after by a religious officer known as a Reclusiarch and the Chapter's holy relics and many of their most precious battle trophies are kept here. The Reclusiarch has an office off to one side, and there are usually multiple private chapels dedicated to a Chapter's primarch, and in some Chapters the Emperor Deified and the Emperor Oracular.Refectory - This area is for the main dining procedures and includes kitchens, store-rooms, disposal units and purification vats. The strict and simple diet of the fighting warriors are augmented by a complex bio-chemical designed to maintain their superior bodies. In most Chapters, meals are eaten in silence following prayers of thanks by the most senior Brother present; but in others, like for instance the Space Wolves, meals are much more boisterous and rowdy events.Oratorium - There are several Oratorium spread throughout the base and these are used for private meetings, lectures, briefings and small assemblies.Hydro-culture - This area contains a supply of local produce and exotic or seasonal vegetables collected and grown for the benefit of the Chapter. Some Chapters often maintain much larger facilities.Terrarium - This space is dedicated to the maintenance and propagation of plants from throughout the galaxy. It provides both a restful area and a source for some of the drugs used in the Apothecarion.Trophy Room - An area of the fortress-monastery where the companies of a Chapter keep their greatest trophies, artefacts, and mementos of their countless battles across the galaxy.Scriptory - There are several Scriptories spread throughout a fortress-monastery and they provide instant access to unclassified Librarium files. These are accessed through a cogitator (computer) terminal and allows users to select, consult and record new entries for the main library.Solitorium - The Solitorium is a remote location (outside the fortress) designed to provide Brothers with a space for contemplation. It can be occupied for anything from a few days to years on end. Space Marines who seek promotion are expected to search their souls and go through self-deprivation for weeks on end to prove their worth.Generatorum - The power source for the fortress-monastery, these massive constructs usually penetrate the surface of the planet, converting geothermal heat into energy via a phased crystal interface (presumably there are many other ways of generating energy on this scale, this is but one example of the possibilities available to the Imperium, which more often relies upon fusion-based plasma generators).Defence Laser - These lasers are mounted in armoured turrets and thirty-two of them remain permanently switched on. The other eighty-eight may be brought to bear within four days of activation.Local Defences - The perimeter of a fortress-monastery is covered in hundreds of separate weapons turrets, including laser cannons and a missile launchers in each.Missile Silos - Multiple missile silos are spread over a Chapter Planet and are the main force of a Chapter's ground-to-orbit weapons. They are each controlled from the armoured room within the Librarium.Penitorium - Space Marine Battle-Brothers guilty of any kind of transgression are held here as a form of remedial and penitent punishment.Dungeon - The Dungeons lie deep beneath the Apothecarion and are home to the common prisoners, but not Battle-Brothers, who would be placed in the Penitorium. The walls are lined with reinforced diamantine although prisoners don't spend long in the dungeons before being taken to the Apothecarion for interrogation.
