Yanko was born in the castle of Denark, the kingdom known for being the most powerful with many cave mines filled with gold around their land. He is an illegitimate Prince, despite that, his father - the King - and the Queen only had two other children, both daughters. Meaning that when his father dies the crown will fall to him.

Because of his "illegitimate" title, there have been many rumours made up about him. That he is a monster with huge claws and fangs - all false, of course.
