Oblivion: Ending Dark Brotherhood

As the Dark Brotherhood's leader, you have but one task to perform: each week go to the Lucky Old Lady statue in Bravil and listen to what she says. Then pay Arqueen a visit and deliver Mother's words. You'll get some gold each time you do that.

Besides, when the Sanctuary starts to fill with new recruits, you'll be able to tell one of them to follow you around. You can call it a free bodyguard.
