In Destroyer's Expedition, Princess Zelda is 17. She lives in Hyrule Castle with her father, the king. She is very skilled in magic, being capable of creating a fireball, making a shield, and warping somewhere else.
The king: Zelda loves her father very much, he is a good ruler, and a good father.
Link: Zelda has strong feelings for Link, but thinks that, since there is no royalty in his blood whatsoever, her father will not approve.
