A Knife in the Dark
Oblivion: Dark Brotherhood Quest
This is the first Dark Brotherhood quest, and is something of an "initiation" that will allow you to join this group of assassins. But first, to even get this quest, you'll need to commit the act of murder.
In order to get the Dark Brotherhood's attention, you need to kill someone without provocation. This means that bandits and quest enemies don't count. You need to find someone walking on the road, or sitting in their house— someone who wishes you no harm and doesn't deserve to die.
Try to avoid killing anyone important. In Oblivion, characters who are central to important quests cannot be killed (they simply go unconcious and are revived later). However, some characters who are helpful in quests can be killed. If a character is involved in a quest, the icon when you approach them will turn to a crown. Avoid killing these people, if possible.
Once you've killed someone, find a secure location to spend the night. This could be your home, or a bedroll at a campsite. (You might need to take out a bandit if you find a bedroll.)
When you wake up, you'll find a man in dark robes standing over you. He'll introduce himself as Lucien Lachance, a speaker for the Dark Brotherhood. He informs you that your brutal act has caught the Night Mother's attention, and that you've been invited to join the Dark Brotherhood. But first, you must complete a task.
If you're interested in joining the Brotherhood, you must fulfill an assassination request. Your mark is a man named Rufio, who can be found in the Inn of Ill Omen, just north of Bravil. Lucien gives you the Blade of Woe as a gift.
If you head to the inn, the owner will tell you that Rufio stays in the basement. You'll find a hatch just to the right of the door that leads outside. Most of the time, you'll find Rufio asleep. You can choose to kill him immediately or wake him and let him know he has to die.
Here's a great chance to increase your Sneak skill. Click the sneak button and walk around the room while Rufio is asleep. As you do, you'll gradually increase your Sneak skill. We recommend you do this until you get too bored, since Sneak skill can be invaluable for Dark Brotherhood and Theives Guild quests..
Once he's dead, go to sleep again (in a secure place) and Lucien will return. He'll welcome you into the Dark Brotherhood. He'll also give you instructions on how to enter the Dark Brotherhood sanctuary in Cheydinhal. You'll be sent there to speak with Ocheeva and Vicente Valtieri and move on to the next quest: Watery Grave.
