===Unbelief===

Despite barely surviving from the encounter with Typhus, it was not yet over for Admiral Quarren's men. Many would sicken and die from disease on the return trip to Belis Corona, but the fleet still managed to return with it ships still usable.

Compared to Belis Corona though, it was pretty bad. Many plague hulks had slipped through the piecemeal blockades arrayed against them, and the same disease that had infected their crew spread like wildfire through the inhabited worlds of the Cadian and Agripinaa sectors. As the plagues killed millions, panic soon spread, and inter-system traffic was halted to contain the pandemic.

As despair and morale among the local populations fell, apocalyptic cults began to appear on every benighted world, and preached that the Emperor's wrath had descended upon everyone as punishment for their wickedness. Only the faithful would be spared the Curse of Unbelief, and masses of self-flagellating devotees began to fill the streets of these worlds, attracted by both their fiery rhetoric as well as their surprising health.

Just at a time when the Imperial Guard forces were begining to have to deal with local mobs killing people left and right, the dead came back as servants of Chaos, the infections of Nurgle clearly serving as a time-delayed invasion tool.

Within months millions of plague zombies clawed themselves out from the makeshift graves they had been buried in among the dozens of worlds in the Belis Corona and Agripinaa sectors, and threw themselves on their still-living relatives. The Guard are pushed to the breaking point trying to contain both the zombie outbreak ''and'' the mobs of zealots running amok, while the Navy was still recovering from the initial plagues, and thus in no position to either defend these worlds or bring in orbital support.

The '''Terminus Est''' at the head of a Chaos fleet entered the sector, to begin running amok against the defenseless Imperial worlds.
