Setting
The Asylians have made use of every aspect of their military technologies to create these defensive bases, each one the size of a moon. The bases provide full service facilities for any size starship, they have a civilian housing section located deep in their cores, save from any assault that does not destroy the station outright.
In the event of an enemy invasion of significant force, lock down commences, allowing the civilian sections to be locked off from the military ones. It takes only five cycles to achieve this, and once achieved, nothing short of breaking the station in half will allow access to the civilian section.
Full support of fighter squads, repair systems, drone automation, and many other technologies, plus a number of psionic weapon and defense networks, as well as the IDT defensive measure ensure that a station can hold out long enough for reinforcements to be brought in via world gate.
Communication within the Baleon Fortresses, and between them, is maintained via Psychoactive Channels that allow instantanous transmission of thoughts, impressions, images, and even feelings to and from the units responsible for handling transmissions and communications.
Advanced detection systems, including Solid State Tachyon scanners, or SST scans, allow the crew of the station to watch the void of space for any irregularities of any sort, including cosmic background radiation. Psionic scouts, and even old fashioned IR and EMG scans, along with regular patrols, ensure that even a fly would not be able to get through undetected.
In short, The Baleon Fortresses are the castle walls that any would be assailant of Asylia would have to overcome before having even a chance of touching her heart.
