Comet Strike

The Comet Strike of 2134 was a huge impact event that caused supersonic shockwaves to travel twice around the world, blew out many hanyo survivariums, accelerated many machines' evolution, knocked over everything higher than a metre and filled the Tarim Basin and much of Australia with seawater. The exact location of the impact is not known, but it is thought to be in the vicinity of Iceland. The Comet itself seems to have been a piece of the Swift Tuttle comet which was supposed to pass close to the earth in 2127. The hanyos made a half-hearted attempt to track it, but it went off the scanners, suggesting disintegration. By 2134, all humans were underground, and the machine data recorded is puzzling at best. The Comet inaugurated the Dark and eventually led to the Flowering. It may have accelerated the already started flip over of the earth's magnetic poles.
