Flight and Fall [ON HOLD]

ON HOLD until further notice given; possibly until Summer or until Next Generation is finished

A Winglock story, influenced a bit by the Maximum Ride stories.
There are five of them. Five successful mutants, avian-humans. They grew up together, a family, their home three rooms in a secret facility. They have never truly seen the outside world, the country of Britain outside where they are, and have no hopes to.
Then there chance comes. To be free. To fly from the prison they have forever been held in. And of course, they take it.
A decision the eldest, Mycroft, forever regrets.
Because they left something precious behind.
