Harrald

Harrald Law-Giver is a male Nord in and the son of Laila Law-Giver.

History
He is a Stormcloak sympathizer who expresses concern about the threat of exile and spies. He thinks his brother, Saerlund Law-Giver, a fool and a traitor, and would gladly see him hanging from the gallows for having the audacity to speak of his love for the Empire.

Kill Harrald and Laila will send Hired Thugs.

Location
He is either in the training area outside of Mistveil Keep, or in the throne room. When the Dragonborn questions him about the son of a Jarl using a dagger, he says it was a training accident and explains that his sword is being repaired by the blacksmith, Balimund. If offering to fetch it for him, it starts a miscellaneous quest. Upon completion of said quest, he gives the Dragnborn a few random gemstones for the trouble.

Bugs

 * If you decide to give Riften to the Imperials during the main quest line, and the place is loaded with Imperial Guards, he may still act as if the Imperials have yet to take over the city. Providing that you haven't started the Civil War Questline of course.
 * After you retrieve his sword, Harrald may continue to use his dagger and his disposition towards you might not change.
