... but I've been thinking about this, and I suspect that not all the paranormal phenomena are of the same origin. The food spoilage is the land's sickness in response to the Dragon's lack of health, but the Bubbles of Evil are directly from Shai'tan, evil, foul, corrupt, twisted things that have frequently been targeted at the weaknesses and frailties of their victims.

And things like the shifting buildings or the Village in Shiota... those are not deliberately evil, I suspect they are the result of the Pattern fraying as the Seals get broken, the Bore gets reopened, and balefire getting used in greater quantities.

So there would be three separate causes for different supernatural phenomena - the Dragon Reborn, Shai'tan, and the Pattern.
