“Rule Forbidden Zones” have been erupting at universities across the country: no turning on the lights in the library at midnight, no looking down at the water in the swimming pool’s deep end, and the thirteenth step in the old lecture hall will make you hear the name of a god. The protagonist discovers that every rule is a “last message” left behind by a dead ancient god. The Eastern Taiyi and the Western Lucifer have both fallen, and their remains are contaminating reality.
