SHING!
Gravis appeared close to his next Law Comprehension Area, the Law Comprehension Area for the Major Law of Lightning's Power. Gravis hadn't entered yet, but he could already see it.
Gravis saw a calm, gigantic storm cloud, which floated above some craters. No lightning bolts left the cloud, and everything was silent.
However, Gravis felt the enormous power inside the storm cloud. It wasn't that the storm cloud didn't have enough power to strike the ground, but that the power had been so incredibly concentrated that it didn't touch anything. It was like all the power had been condensed on a single point, and the power even grew as time passed.
Gravis looked at the craters and could guess what happened here. The storm cloud would continue to gather more power until the power became so enormous that everything would unload in a single lightning bolt, which would create another crater.
