So... you just went into his nobles house, talked to him, went into his quarters, lockpicked his desk and found the note about the assassination of Brianna. I really don't think we have to speed things up since Shogun said he would be happy to be the bad guy, so we could give him some time to work.
What could make a little more sense would that maybe, me and Deagan encountered each other in Lainlalten. Maybe Deagan threw out something convicing or something, so that Hecate wouldn't kill him as he really wanted.
Hecate starts trusting Deagan...
Shogun who will be controlling the bad guy will be one who sent the letter to Hecate about arranging a meeting. Both of them meet, talk about this and Hecate wants to have the job to kill this pregnant woman.
Since Hecate starts to see Deagan he get's a little bit uncarefull and tells Deagan about the assassination. Deagan is like "holy cow" you know, because out from the details and discription he knows it's Brianna.
From there we start working - Shogun won't tell Hecate about the prophecy, only hand out a large amount of gold. So all Deagan will know is that someone wants Brianna dead, but not why.
From there we get into a few assassination attempts. Then a little more in, we start to unfold this mystery when you (Arygon) get back with Brianna and the rest, and maybe one of these wise women who have been following Arygon or what ever they've done, see Brianna and want to speak to her...
Something like that... That's just my thought - since I think things are unfolding to fast with you suddenly finding out about both the prophecy AND the assassination of a pregnant woman...
