Ok thanks for comments...
I'd have to agree with the fungrin stuff - thinking about it I'm not really sure why that scene is the way it is, though I liked both the scene and the character at the time.
For the Maghin scene - I will sharpen this scene, I agree it's proabbly a bit too long-winded and vague. It's there not to get you feeling for Maghin Chatka, but to:
1) Show the resurrection of the Third
2) Display a little of the heirarchy of the Order
3) Show that the Maghin is not actually as powerful (politically) as he should be in theory, and then finally...
4) Bump him off so that the new Maghin can come in. You've only seen a little of the new Maghin (Dunis Cho) so far, but he plays a bigger part later on.
It can't go further in the book though, because it happens before everything else! The new Maghin takes over from him, and I want him there ready to talk to Orm (there's a bit more going into his dialogue with Orm once I get round to the re-write, that should hopefully add to the feel).
The Yanish bit - definitely isn't going into the prologue. It's the start of the linear story.
The stuff with the Third in the prologue takes place about a month before the rest of the story, and it relates to stuff that you won't know about for a long time yet... so it's place is justified, trust me

It's important for reasons that won't come clear until later.
I'm a firm believer that the prologue should be set apart from the rest of the story in some way, whether in setting or style. It should be removed or abstract to a certain extent, and should hint at developments or stuff that you won't understand. I think that if you don't do this, and the prologue is just the first part of the story, why is it a prologue? Why not just call it Chapter 1 and be done with it?
Granted, mine needs work to get it right, but it's definitely staying as it is - hopefully you'll agree once the pieces come together.
I'd have to add though... a big part of this story is the mystery aspect. I know that a lot of stuff isn't going to make sense at first, and the majority of that is on purpose. I'm trying to get it so that the reader has enough to go on for the time being, and their curiosity is piqued, so that there will be pay-off later. Of course, it's getting that right that's important
