Woah! Nice slice of action indeed. There be dragons: probably the whole concept of dragons arose (China very very early?!?) from ancient visitations by cometary or asteroidal bodies that either came very close, or within the upper atmosphere, or even coupled with impacts individual or multiple, of the earth - back when those now well understood cosmic bodies where completely misunderstood and a fearful things indeed. Can you imagine it? There be dragons! Or comets, maybe...!?!
