In 2043, the "red fog" swept across the world, shrouded in blood-colored fog day and night, causing electronic equipment to malfunction and human civilization to collapse. The red mist gives birth to "abnormalities" (zombies, alienated animals and plants), and also hides an ancient vampire group - they are not products of the red mist, but they awaken in troubled times and regard humans as blood food and "blood servants" (low-level transformers).
