You were about to leave whiterun when Lydia runs up to you "Sorry we didnt have a chance to properly meet, but my names Lydia and The Jarl has appointed me to be your housecarl. It's an honor to serve you. The Jarl has recognised you as a person of great importance in the hold. A hero. The title of Thane is an honor, a gift for your service. Guards will know to look the other way, if you let them know who you are."
