The members of the eternally stoic haruchai call this abomination a "fall". I call it "Holy crap! Let's get outta here!"

Another term for a caesure and the one most used by the haruchai, the Masters of The Land to describe these perversions of the natural order of things. However, no matter what you call them, being swallowed up by one of these time- and space-splintering eldritch tornadoes of the mightiest of arcane puissance is going to seriously screw you up.

So, on that basis... run away! Run away NOW!
