The courier with the Dark Brotherhood's message has not arrived. It has been several days since I have completed the quest.

Is there any way to work around this issue in order to begin the Dark Brotherhood?

You don't need the courier to start the quest. Just sleep.

If the courier doesn't appear after waiting a few days, sleep in a bed for at least 8 hours and the quest will continue.

• Sometimes this can take several days, even with sleeping.
• If the courier still does not appear, try fast traveling to a different hold and waiting.

You don't need the courier, unless you want to begin a collection.

You don't need to sleep 8 hours, one is enough and you can sleep anywhere: a guard bedroll, your bed at home, a bed in an inn, any bed in which you can sleep actually.

By the way, Dholland662, you did report the murder to Aventus, did you? If you didn't, you'll never be able to be abducted by Astrid.

Ha, ha okay then...
