Maniac Storms are sudden shifts in reality caused by a change in belief in the Consensus. Essentially, one of these happen when the consensus as to what is "true" changes, such as people suddenly ceasing to believe in the theory of a geocentric universe, or a hollow earth, or even the notion of mythical creatures. These events paradoxically spawn Manes, and in some cases, Bardos.

Maniac Storms are often very quick and last an instant where old theories are discredited and releases floods of untapped mania that spawns bardos and causes new and originally mundane scientists to become Inspired.
