Kill the Dragonfly

In this place and time, twins are considered as something sacred. At the age of 3, they are brought to the King to determine which one becomes the "Successor" and which one is "Disposed-of".

It happens to be that one of the twins was able to escape their death, getting a new start in life.
Being 3 years old, everyone believed that the twin died in the wilderness.
But what if that wasn't true?
What really happened to the run away girl?
And is she really what everyone thinks? Or is there more to what the eye sees?
What truly happened to her?
And who saved her?
