From publisher blurb:
TheDarkmaster toils endlessly to bring ruin to the world, crafting more horrific plagues, infections, and creatures along the way. The brutality of the world works ever harder to force nature into the endless arms race of survival, and disease is no different. Civilization forces the people of the world into ever more crowded and unsanitary conditions in the name of progress and safety in numbers.
These two-dozen new diseases are mere examples of the infinite festering conditions simmering in the pot of corrupted nature. They are designed to run the gamut of sicknesses and mechanical impacts on characters to enrich the struggles and triumphs of you characters, ranging from inconvenient, to dangerous, to outright deadly.
