Writing exercise – If magical, dragon-shifting humans ruled the world…


You are 16 years old.  A race of magical, dragon-shifting humans has taken over the earth and everyone is captured and removed to training camps, but for what type of training, you are yet to learn.  The elderly are deemed useless and ‘removed’ from society, including your beloved grand-parents.   After several months of  painful mental and physical ‘testing’, you find out you are to be eliminated and are thrown into a pit with others like you…others unworthy of the new race.  Unworthy to live.  Determined to stay alive, you brainstorm and discover there is one thing that exists that can return the world to  normal and rid it of the black magic that has veiled the world.

What is that one thing and how do you get it?  Feel free to elaborate.
