APOSTLE system – the Automatic Planetary Orbital-Stationary Tactical LinE – is Salangan integrated protection system. The first version of the APOSTLE was built many billions of years ago, but during the First War it was completely destroyed.
Subsequently, the system was not only restored and modernized, but changed many times. APOSTLE-13 is the latest version of the combat system, installed directly in the bark of Salangan; more and more later modifications were located on the Heaven floors, and during the Exodus Salangans took these systems with them.
At the same time, APOSTLE-13, obsolete and disconnected billions of years ago, was modernized (equipped with CHAOS-weapons) and re-activated to guard the now deserted planet.
