In the years just before the final solution of the Final War was inadvertently released, the Hard Times that effected Deneb Sector as well as the rest of the Third Imperium, left their mark here. It was not as bad as some of the Black War in the old Imperial mains, however occasionally dastardly efforts were conducted, in this case by Vargr and more infrequently, by the Imperial Navy.
Filangger (2001) had hosted an Imperial resort before Vargr occupation. Secretly, the Imperium had also maintained weapons research outpost nearly equivalent to a research station, but this was purely military. It was fairly safe on the ocean bottom well away from any civilized habitats, but had nevertheless been evacuated when the Vargr came. To assure that the Vargr would gain nothing from the abandoned outpost, it was heavily bombarded by a taskforce that has forcibly made its way into the system.
An unpredicted outcome of the bombardment was the shifting of a crustal plate which resulted in a subterranean outgassing. The gases caused a lowering of the planet's surface temperature. The seas rose and the former Waterworld became a Glacier world. All things being equal, this mini-Ice age should last another thousand years.
The Vargr on Dzoungdzi (1802) had permitted a large and corrupt Corsair band to stash a munitions dump on their world. The corsairs had not told the people of Dzoungdzi that this dump would also have some chemical weapons as well. Imperial Intelligence had discovered the dump, but had no foreknowledge of the particularly insidious nature of some of the containers. The dump was bombed from orbit and the explosion resulted in a mildly unhealthy chemical taint in the planet's atmosphere.
