Revolutions

The Nine Revolution Skybreaker Bone Structure… It was one not just of Lightning, but of Thunder as well. 

Often, these two concepts were confused and combined into one, but this Bone Structure made certain that it was impossible to forget the latter. 

Thunder was the product of superheating the air. Another neglected fact about Lightning was just how hot it was, and it was this overwhelming heat combined with its speed that caused small sections of air to rapidly heat and then cool down. 

It was this process of expansion and contraction that triggered the thunderous booms usual for storms. 

However, these were forms of lightning that were often neglected because it was too fast, too powerful. Who cared about heat when your lightning was fast enough and powerful enough to pierce right through the head of an enemy like a blade? 

By extension, though, lightning was also extremely difficult to control.
