For the past seven centuries, Sentinel Towers had been things that the monsters wandering the wasteland avoided at all costs—even mindless Aberrants and wandering spirits born from abandoned magical energy instinctively kept away from these dangerous facilities, brimming with immense energy and capable of releasing purifying beams at any moment. It was rare for monsters to approach a Sentinel Tower in groups, and for them to launch an attack of their own accord was unprecedented.

The ancient Alert Devices remaining around the tower could no longer stand against the assembled Aberrant legion, while orders from the upper Command Node had dispersed the instinctive resistance lurking within those monsters' chaotic minds. At a single command, tens of thousands of Aberrants and magical-energy spirits turned across the wasteland, aiming their terrifying spearhead at the magnificent tower standing upon the wasteland highlands.
