Gerda

"I might just be a servant among lords, but don't think for a moment I don't take my duties as seriously as the Jarl himself takes his!"

- Gerda

 is female nord in Dragonsreach, within the city of Whiterun. She tends to the needs of Jarl Balgruuf the Greater, serving as a maid in his quarters. She may also send thugs after you if you steal from Dragonsreach or Whiterun in order to, "teach [them] a lesson."

Gerda doesn't appear to like the Dragonborn. If the Dragonborn is standing in front of her, she will say, "No one is higher than the Jarl in these halls."
