POD's that cause Magic to reappear in a magicless world

Special thanks to Adam

The Bavarian Illuminati and or the Initiated brothers of asia contact "something" which is probably better left undisturbed, it rolls over and hits its metaphysical alarm clock, and wowie zowie magic appears

Halley's comet returned in 1834, and magic returned with it.

Ghost dance 1890. The Indians have had enough of getting pushed around by the U.S. and aren't going to take it anymore. Around the time the white folk having Seances. Sprinkle a little voodoo and you have a paradigm shift.

in 1908 the capstone that kept magic out of the world for centuries blows, and magic returns to the world. Violently

Alister Crowley: Mister Crowley gets that special package he's  waited for his whole life. ( it's symbolic of course)

1939 to 1945 Hitler Himmler and his "Order of the deaths head" trips over a metaphysical singularity, Coinciding with the population of Germany being "On vacation"

(From Adam) 1943 in the Philadelphia naval yards. A destroyer Escort, the USS Eldridge, has been fitted with a brand new "stealth" Generator. The Generator is capable of rendering the entire ship invisible to both visual and radar scans.

It's bad enough few people know of its existence, worse that even fewer knew how it worked. Because to be invisible, the ship had to break through time and space. and that's what happened.

1946/47 L ron Hubbard, and Scientist John Whiteside Parsons enact the "babylon working" in a California desert, coincidentially about the time of Alistar Crowley's death, and an upsurge in flying disc sightings. (we can't stop here. This is bat country!)
