The Dark Brotherhood Forever

"Accept his gold, then kill the target. So begins a contract, bound in blood."

- The Night Mother

This quest is a Radiant Story quest and repeats infinitely.

Background
''I am now the Listener and leader of the Dark Brotherhood in Skyrim. It is my duty to hear the words of our unholy matron, the Night Mother, and do as she commands...''

Walkthrough
The mission repeats itself with the three objectives: Approach the Night Mother's coffin, speak with the contact, then kill the target.

After eliminating the target, a new one can be initiated by returning to the Sanctuary and speaking with the Night Mother. The Night Mother may contact the Listener telepathically with new contracts, although this is usually not the case.

Targets are randomly generated the moment the quest begins. Re-loading saves before speaking to the contractor can be exploited to gain a specific target. This may be useful for unlocking the "Master Criminal" achievement or trophy without killing Essential characters.

Bugs

 * The Reckless Mage in Winterhold may sometimes appear in the inn, even if the player has not approached the Night Mother or the client. Killing him will result in the quest completing permanently.
 * There is an exploit to get double the gold from a client, walk up to them and let them talk, when they start talk hit A, X or E, you will get the gold they were going to pay you, then they will repeat what they were going to say, let them finish and you will get the same amount of gold given you when you pressed the talk button. This does not work every time in the patched version.
 * For some reason if you kill the Grim Shieldmaiden in Markarth or the Traveling Dignitary in Solitude, the city guards will attack you despite you being hidden and them being far away. (This sometimes happens in the patched version). A workaround for this is to pickpocket the target and get caught, causing them to attack you (make sure you're far away from any guards when you do this). You're then free to kill the target or allow the guards to do it for you; you'll get credit either way.
 * There's a trick to killing target NPCs in crowded areas without drawing aggro or a bounty. Make sure that 1.) you're sneaking; 2.) there are no guards or NPCs in your immediate vicinity; 3.) you are far enough from the intended target for the quest marker above his/her head to NOT show. Use a bow to hit the target, and provided you A.) have the proper bonuses to ranged sneak attacks, and/or B.) the target is unarmored, the target should die instantly. Furthermore, if there are any NPCs in the target's vicinity, they won't even skip a beat. You can even walk up and loot the body or get your arrow back, and the other NPCs will act as though nothing happened at all. Tested on the Traveling Dignitary  [In solitude [PC] NPC's do comment  about the body and the guards do attack] and Ma'randru-jo. Does not appear to work on Grim Shieldmaiden guards still attack irrespective of the distance between you, them and the target. Only workaround found was a frenzy spell or pick-pocketed frenzy poison. (Tested 360)
 * There's another trick to this, simply equip the fury spell, make sure you're hidden, and cast the spell on the target.
 * Commanding a follower such as a Dark Brotherhood Initiate or Cicero to kill the target for you will prove an adequate workaround.
 * Sometimes, for some reason this quest may disappear from the active quest list, so then the quest won't restart. If you desire to bring back this quest use the console with the command setstage DBrecurring 200
 * Sometimes, when you enter the Penitus Oculatus Outpost, none of the NPC's will interact with you, including the contact named "Corrupt Guard." One way to fix this is to steal some items from the table and have the outside guards come inside to attempt to arrest you, get them to fight you until all the witnesses are dead and you are finally able to speak to your target. Another solution is to quit the outpost, wander a little on the wild and killing things, and then return to the outpost. Or you can just exit the building and walk back inside...
 * Sometimes upon killing a contract and completing the Dark Brotherhood Forever quest, game will freeze when the quest resets.
 * Sometimes the Dishonored Skald will not talk to you or interact in anyway. There is no fix and this will force you to abandon the quest.
