You were sent to the city of Gerudo in the desert by Princess Zelda. She did not tell you your mission, only to deliver a scroll to their King. So you made the journey, and when you were finally allowed before the King, he glared at you, like an insect.

"Who dares to approach the king? Speak quickly, for I have little patience for idle chatter." His voice was deep, imposing, and menacing, the very air around him charged with his magic. Seems you cannot waste time then.
