Pandora's Box

Tourists think this town is magical.
That's because it looks like it belongs in a fairytale.
It's not.
But it's the home of a family that are quite magical indeed.
You would them find the floating around aimlessly while reading...
Nursing flowers back to their youth in seconds...
And even summoning the elements in the palms of their hands...
A loving couple raising their seven foster kids seem nothing out of the ordinary. They are content with their lives but not so much themselves. Just like everyone else they have their deep desires, big fears and secrets that don't deserve to be said out loud.
They have become used to living a life where they hide most of themselves.
But they were never given a reason why.
Why are they living like this?
Why were they only kids when they came here?
What is the real reason they're forced to stay hidden?
