Say you hear rumours that Commander Maro is recruiting a new faction dedicated to stopping the Brotherhood. You talk to him and he tells you he needs your help ASAP. He reveals that a shady character has been, for example, creeping around Ivarstead. He asks you to check the scene out, and as you get there, an assassin in the DB armour is making his killer move on Narfi. You kill the assassin and report back to Maro, who gives you a gold reward and thanks you for saving an innocent life. This could continue for a while. You would prevent contracts from being carried out. And then, after stopping these murders, Maro says, "We received information of an assassination attempt on the Emperor. You will be part of his personal guard." You then kill an assassin as he escapes from the murder of the fake Emperor. Finally, you join the Penitus agents as they assault the Dark Brotherhood Sanctuary.
I thought it would be cool to have an alternate questline rather than what we have now. Just an idea and I'm sure some people will pick holes in it but hey, I think it'd be good. ^-^
