Jat-Krula

The Jat-Krula, or the Maginot Sphere, is a complex structure. As a higher-dimensional fortress designed to protect the Orion Complex, it comprises millions of defensive stations spread across a bubble of thousands of light-years, all calibrated specifically to block any incoming approach vector into the Orion Complex from the outside galaxy. As such, it is far from a straight line or even a bubble. In fact, the line installations' pattern is seemingly random, but has its own logic to it - one that is only apparent when viewed from within Slipstream space; the closest terrestrial analog might be an early modern star fort, but in three dimensions. Single line installations hardly protect any location in particular, but work in concert with the others to form a supposedly impregnable chain. This, however, also was the cause of the system's downfall. If even a handful of facilities were disabled, it would compromise the entire Line. By the present day, only a small fraction of the system remains active and in synchrony with the rest of the Jat-Krula array, but the relative few (which still include tens if not hundreds of thousands of stations) have still caused considerable inconvenience to the modern civilizations.
