Need some help getting started in the Dark Brotherhood. Wiki really didn't tell me in full detail, just talked about the quest when you talk to Aventus Arentino.

I did his quest, killed Grelod and my friend said to just go to sleep (24 hrs max) and someone will awaken you and ask you to join, etc. etc. I did this twice now I've slept 24 hrs.

I even went around the Stone Quarter of Windhelm and found someone to kill (Nils) just so I could get thrown in jail hoping that would do it. And it didn't.. so why am I not being greeted here?

Don't get it..

Did you get the Mysterious Note?

Nope, I have nothing. Just says "Innocence Lost" is completed.

The key phrase from the wiki is: "Sometime after you've killed http://www.uesp.net/wiki/Skyrim:Grelod_the_Kind and received your reward from http://www.uesp.net/wiki/Skyrim:Aventus_Aretino, the http://www.uesp.net/wiki/Skyrim:Courier will approach you and deliver a http://www.uesp.net/wiki/Skyrim:Mysterious_Note_%28DB%29 bearing the ominous words "We know"." So maybe wander a bit so you run into the courier.

Okay I tried sleeping a couple more times in Windhelm, nothing. Go to Riften and rent a room, sleep.. and BOOM starts up? Like, did I have to be in Riften or something I don't get it? Lol.

But I'm all good now it started, just got outta the Shack. Thanks for the help!

There is probably a random or unspecified amount of time that needs to pass between you killing that poor old defenseless lady in the orphanage ( ) and the courier delivering the note.

I bet you haven't returned to Arventus Aretino and received your reward have you? I did the same thing on my assassin, haha

The note doesn't need to be delivered. But it is random. One time I went from Windhelm after returning to Arentino to Kynesgrove, and the courier shows up. Another time it took almost a week of game time.

3 days have to pass and try sleeping at the inn in Riverwood, that always worked for me. Also, check your inventory for the mysterious note, its the one with a black hand on it. As long as you don't open that note, they won't contact you or visit you when you're asleep. Hope this helps.
