On the very next day, the group found another obstacle on their path. It was a relatively small town. If their goal was to invade and conquer, taking that place would be easy, but that wasn't their goal. In any case, dealing with a small town would be a bit more troublesome, even though Billy had two ways to deal with the situation. The second seemed better, but he decided to hold that idea for an emergency and he used the difficult one instead. Billy's idea was… To make rain like hell in the area.
For someone who used ThunderStorm to fry some dragons, making it pour was easy. Billy created some clouds when night fell and made them move to the town… Once that happened, he made it rain and that decreased the visibility of the people around, the rain also erased the footsteps that they left behind.
