Honor is (Un)dead

It all started with a cough. In the wintery tundra of Edo Period Japan, this would be passed off as a mere fever in the cold climate of the season. But it was more than that. People died, rising once again as savage parodies of themselves, attacking anyone near them. But it was merely passed as folklore, vengeful spirits and such nonsense, another one of those cautionary tales, but never taken seriously. Now the entire country is infected with these horrors beyond comprehension, desperation is as common place as the crimson-colored blood that stained the pure white snow. Honor is dead, the government has fallen, THEY have risen.
