Crop circles and fairy lights?

[not_technicolor]

[Tonight, out in one of the fields there is a dragon-sized circle oval of well trampled stalks and floating just above the corn are fist-sized balls of light/fire. Most are shades of blue and white but there might be a golden or brown one in there too. They look like they're dancing. Investigate?]

((Shima is playing with his magic. The balls are cool to the touch and people can pick them up and carry them (or catch them in baskets, as the case may be)))
