Beneath the bustle of the modern world lie hidden passages between the realms of yin and yang.
When ordinary people violate taboos surrounding funerals, homes, travel, or worship, they may attract vengeful ghosts, corpse demons, evil immortals, or gu poison monsters. Dark cultivators, clans that raise ghosts, black-market spirit merchants, and fallen gods of the netherworld also wreak havoc in secret.
All things are bound by cause and effect. Ghosts and monsters do not harm people without reason: resentment, curses, human wickedness, and an imbalance in the order of Heaven are all roots of disaster. Daoist arts, gu magic, and feng shui counterbalance one another. There are no effortless power-ups; victory in a battle of magic depends entirely on the arts’ strengths and weaknesses, as well as strategy and planning.
