He's talking about the task he gave the player character in Oblivion, to kill all the members of the Cheydinhal Sanctuary. This quest was called 'The Purification'.
When LaChance was a member of the Dark Brotherhood, 200 years previously, it had a code of honour that was usually strictly adhered to. He clearly does not approve of the ways of the current Dark Brotherhood.
The only accessable Dark Brotherhood sanctuary in the game is the one in Cheydinhal and the Black Hand does not meet in any specific place.
the only person you get, is the high elf that accidentally kills the wrong traitor( i dont know if u beat it or not, so spoiler alert). the listeners kill Lucien Lachance by mistake.
yes he did because he comes up in your crosshairs when he walks out
No!
Hell no Assassin's Creed Brotherhood is way better
The Dark Brotherhood is simply a side-quest in the game. It isn't crucial to the storyline but being in the Dark Brotherhood allows you to get weapons/spells/etc. that are normally unattainable.
its not a cheat code, you get it when joining the dark brotherhood
To get in, you murder someone - kill an innocent person who did not provoke you. I recommend a Nord woman in Bruma called Alga, because she respawns. Then, the next time you sleep, a man named Lucien Lachance will visit you. He will instruct you to kill a man named Rufio at the Inn of Ill Omen. He is most easily killed in his sleep. Do so, and then the next time you sleep, Lachance will visit you again and confirm your initiation into the Dark Brotherhood as complete. If you want to finish the quest to join it quickly, simply sleep in Rufio's bed after killing him. Then go to the Cheydinhal Abandoned House and enter the basement. There is a tunnel dug out of the wall. At the end of the tunnel is a black door - activate the door. It will ask the question, "What is the colour of night?" Answer, "Sanguine, my Brother." Then go through the door, and speak to the Argonian in front of you - Ocheeva.
If your a high enough level (somewhere around 20) you can get them from either the dark brotherhood or off of a creature in oblivion.
You can only get the Languorwine Blade during the Dark Brotherhood quest, The Assassinated Man.
if you mean the dark brotherhood armor kill someone then sleep until you get invited into the family
It is already enchanted so you can't do anything to it.
