Honor Thy Family

Have you slighted a member of the Dark Brotherhood Family? They aren’t concerned with you stealing anything from the Sanctuary, but they draw the line at violence. This objective triggers if you strike (accidentally or otherwise) any Family member once and then sheath your weapon. This is important; continue to brandish your weapon, and the whole Family turns hostile! After you calm down, you are instructed to speak with Nazir and pay the fine imposed for your behavior. Return with 500 gold pieces, and you may continue working with the Dark Brotherhood.
