"Here's all you need to know: I'm a werewolf. I like killing things. I love Astrid. I hate annoying people. And the color blue gives me a headache."


Arnbjorn is a Nord assassin and a member of the Dark Brotherhood, as well as a Werewolf. He is married to the leader of the Dark Brotherhood, Astrid.


He is an ex-member of the Companions. He was asked to leave because his "unorthodox" methods were offensive to other members. It is unclear what these methods were or how they were offensive, however, given his current status, it seems possible he used underhanded, duplicitous techniques that would have offended the Companions' sense of honor. He joined The Circle and became a werewolf prior to his expulsion.

He initially disapproves of the Dragonborn, showing a rude attitude, but after several successful assassinations, he begins to respect and even envy the Dragonborn.

If the Dragonborn is also a werewolf, however, he will immediately know and react a bit more amiably. Regardless of whether they are a werewolf or not, Arnbjorn will use little nicknames such as "lambshank," "beef roast," "tidbit," or "hamhock." He says not to take offense from the nicknames.


The Cure for MadnessEdit

When returning to the Sanctuary after killing Gaius Maro, there is Astrid and some other Dark Brotherhood members standing around Veezara, who is wounded. Astrid will tell the player to go chase after Cicero, who attacked her and the other Brotherhood members in a fit of rage over their dislike of the Night Mother. Astrid also tells the player to find her husband, who chased after Cicero to protect the other members. After traveling to the Dawnstar Sanctuary, Arnbjorn is found heavily bleeding outside the black door, unable to continue.

To Kill an EmpireEdit

Arnbjorn is killed during the assault on the Dark Brotherhood Sanctuary, where he dies in werewolf form while holding off Penitus Oculatus agents. His death is scripted and he will still die even if the Penitus Oculatus are killed first.

Destroy the Dark Brotherhood!Edit

Arnbjorn is one of the assassins needed to be eliminated if the player kills Astrid during With Friends Like These...


  • "Should have figured Astrid would send you."
  • "Gee, thanks for the help."
  • "What gave it away?"
  • "Do me a favor and kill that little jester twice. Just to make sure."
  • "Sister/Brother."


  • He wears a unique short sleeved variation of the shrouded armor. If the armor is stolen and equipped, regardless of the character, it will have long sleeves.
  • He never wears any sort of footwear or gloves, possibly due to his Lycanthropy.
  • He is the only Dark Brotherhood character who will never give any useful advice when asked for it before a mission, apart from Cicero, who does not have that dialogue option.
  • He can sometimes be seen in the forge part of the sanctuary attacking nothing because of movements made by two-handed attacks. He may be seen using a dual one-handed power strike, despite using a two-handed battleaxe.
  • He, like many other members of the Dark Brotherhood, thinks Cicero is insane.
  • When he dies at the hands of the Penitus Oculatus, Arnbjorn will have the body piece of the Shrouded Armor in his inventory. However, if he is killed during Destroy the Dark Brotherhood!, he will only have one or two randomly enchanted battleaxes in his inventory.
  • When returning to the Sanctuary after finishing the first contract(s), when everyone is gathered around the Night Mother's coffin and her Keeper, Festus Krex calls Arnbjorn a "great lumbering lapdog" when he is rude to Cicero. Also, during The Cure for Madness, Cicero calls Arnbjorn a "stupid wolf" and "hulking sheepdog," in derogatory reference to Arnbjorn being a werewolf.
  • He appears to dislike daggers, as he calls the one wielded by Cicero a "butter knife."
  • Out of the rest of the Brotherhood members, Arnbjorn is the most disrespecting to the Night Mother, even going as far to call her Cicero's "pet corpse."
  • When greeting him for the first time during Sanctuary, he calls the player character "fresh meat."
  • Arnbjorn's death is scripted; even if the Dragonborn kills all the Penitus Oculatus agents attacking Arnbjorn, he will simply collapse and die, seemingly without cause.
