The indoor thunderstorm came from one source: a little girl no older than twelve. The superpower, despite how destructive it looked, wasn’t actually dangerous, if she could actually control it.
In the past, they would have locked her away for everyone’s safety. Now there were laws against that, so they had to get creative. Considering her age, they decided to lock away her powers and keep it dormant until she was ready.
For years, it was the perfect solution. Then she finished high school, and her parents requested for her powers to be returned so she had some form of self-defence when she moved out for college.
Except, the power wouldn’t wake up.
