You will likely meet Arnbjorn where Astid usually hangs out, in their bedroom, which is fantastic as you can fight him one on one. Well, regardless of the “Commander’s” poor decision-making skills, head on over to the Dark Brotherhood Sanctuary west of Falkreath and head inside the sanctuary. Honor? This guy wants ONE person to take on the whole place. He’ll tell you to head over there and put everyone inside to the sword, as it should be “our honor”. He’ll tell you the time to strike is now and give you the passcode for the Dark Brotherhood’s Sanctuary door: “Silence, my Brother”.
Tell Commander Maro the news and he’ll be ecstatic. Head on over to Dragon Bridge and enter the Penitus Oculatus Outpost. Once you do that, you will be told to report to Commander Maro, in the village of Dragon Bridge.
You’ll then be told to report what you did to any guard (and it really doesnt’ matter who you report it to). With the leader of the Dark Brotherhood dead, you can free the captives, loot her body, and escape.
