Becoming a true knight

To be recognised as a Knight and therefore be eligible to save a princess and become a king or queen you have to do some work for a current king. Saving villages, killing orks and other small monsters, that kind of thing. Of course, the king in this land is your father and the princess to save your sister with the dragon to slay your mother; this poses a problem.

Your father has never seen you but you mistakenly have his eyes and a few other facial characteristics. minus the dragon parts, you look like a younger female version of the king. You have hidden your wings and tail under a long brown cloak and your blue scales are under your armour.

You could travel North to the next kingdom and become a knight there or South East to the castle of your father.
