The Cunningham family was different, Extraordinary, special, whatever you say. Orlean Cunningham was having a special power since the day he was born. He could control and talk/communicate with different elements such a fire water, etc. His wife Nancy Rivers wasn't any different. She could levitate objects since the very beginning. And when they found each other, they knew, they knew they had someone in their life they could finally trust. So what did they do? They married each other. Their children were not any different. Elena the oldest, was 12. So was the oddest. She was the most powerful in the whole family. She was a sorceress. She could levitate, cause, conjure etc. But she lacked the powers of her siblings. The Cunninghams had two more children later on. Kelson and Kaelyn the twins, CURRENTLY 12. But unfortunately they lost Elena in a fire.
Orlean and Nancy knew that they had to give their twins the proper education so, they sent them to BLITS VALLEY SCHOOL OF EXTRAORDINARIES. There Kelson and Kaelyn would find people just like them and would be taught the right use of their powers and not only how to use their powers but muggle studies ( in words of Harry Potter).
"Listen both of you, we've been to Blits Valley in our childhood. It is a really peaceful place. But please just be careful" Nancy explained to her 2 12 year olds.
