Description:
Large, Grey, Black and Imposing, shaped as the fortress it truly is, it might make bastion take note! This is exclusively a One Sith Command and Control Facility in the heartlands of their empire. It is large, heavily fortified, garrisoned well, and like most structures on Coruscant has several levels to it, some connected, some not. Above it there are several thousands of regular civilians going about their daily lives, elite of the military OS command making home among them in luxury, while below much of the surrounding space was cleared when the Galactic Alliance destroyed central centrax. The rest of the rubble since removed to leave a wide 25km firing zone around the ground of facility, exactly built to fit the Large Eros's firing range. There is cover dotted about in this zone to provide pillars for buildings above, but not a lot of it. Above this is not the case, with 2km at most of room to shoot, making any attack on the facility from above perhaps advised. What is above, are nestled turrets, small and large, with their own shield generators, often hidden in the structures themselves, that is the real danger here for anyone approaching, the angles you can be shot from in such an urbanized area, as well as any militia present.
Other challenges to be noted, are that you are moving through a civilian population center above, commercial, entertainment and business districts from Coruscants often many levels. A clever and ruthless commander might drop the entire lot down on the command centers head, the OS being a Sith Empire understand this vulnerability, their layers of shielding and their physical Turadium Blast shield built to withstand substantial collapses above and civilian loss of life should it come. Their Turadium Blas shield protects the inner wall and further inward, but not outside of it. Below you don't have that problem so much, it is a straight ground fight, but you do have a lot more guns at their optimum range to face, and the possibility of collapsing structures or debris from above during any firefight!
Two layers of walls at differing heights exist outside, each mounted with turrets. While outside there are perimeter scouts from the 771st scout infantry, as well as militia and sensors to report any trouble, you'll find walkers and tanks on patrol at regular intervals the closer you come. Inside there are many tight corridors, security check points, scanners, and at least four layers or grades of security with higher level keycards needed for each. Getting in an out the proper way takes time, even for a sith lord, as everyone is checked before they can enter the Command and Control heart of the facility.
In the very bottom lies a bunker, several hundred meters below the surface, also built of Turadium, it has room enough for perhaps 100 people to live for a month, with the living facilities a small population would require, and droids to assist. There is one lift down and only one, no other way to the surface should those people become trapped and no other way for anyone to get in to help them. The bunker is capable of broadcasting and acting as an emergency C&C for the surrounding forces, only with reduced range given it is underground.
Perhaps the most significant part of the facility, in its center, is the memorial wall, which you can see from the command center directly. A large black and golden holoslab of all the 769th's dead. Those present can scroll along the many thousand names and the conflicts they have been apart of. It too is heavily shielded, with room for ceremonial purposes to add more names as they come. The 769th are not clones, they are taken from the surrounding population, the only corps from the 5th army to do so. As such the 769th prize this memorial as sacred above all else, and will lay down every single life to protect its memory.
History:
Central Centrax was originally a bustling metropolis of some density, like the rest of the planet. Above you had the elite of the Sith Navy, and below them the many workers, average joes who keep a city alive, going about their day to day lives. One tragic day, it became the site of the Galactic Alliances's orbital fire, when one of their number fell unconscious at the controls, during their skirmish on Coruscant. This tragic death created the true fighting spirit of the 769th, being one of the few regular corps to exclusively use non clones, not just for their officers or specialised roles. The individualists as they are known, are fanatic in their defense of their homes and loved ones, in this historic place most especially of all.
Later during wargames and the formal founding of the 5th Army the facility was improved, fitted with the latest tech and as the 5th army itself was developed, and its command structure put into place, Centrax became one of their main nerve centers of operation, seizing the benefit such a symbol brought to the 769th stationed there.
Intent: Coruscant Command and Control, and for the upcoming invasion by the galactic alliance.
