Over the last several months, the world has been rocked by a strange phenomenon: waves of unconsciousness engulf the entirety of the known world, rendering all sentient creatures unconscious. These ‘Psychic Events’ have no warning and occur at random times. They are consistently followed by turbulent storms sweeping in at high speeds from the East a few minutes after the Event subsides and creatures begin to regain consciousness.
For some unknown reason, several members of the PCs are immune to the unconsciousness. They are warned with swiftly-building headaches that break at the moment of the Psychic Event.
The PCs have recently found out that there are other creatures that are immune to the Psychic Events.
