I really liked how your magic systems seem to be built. Very interesting and great possibilities. I did however get a little confused as to how the sword worked. Was it his blood that fuels it or is it blood in general that makes it work. Second i think i agree that your characters need a system of beliefs to check their actions. Its obvious that Till feels guilty about what he did in the past, hence the soup kitchens ect... but this same regret is not presenting itself when he is killing people or speaking with his clients. I know your planning on doing something with this already, so I guess what i would consider is this if he was a thief in a former life his system might be a little skewed if only because in order to do things like steal or murder your mind would have to be able to reconcile your actions. So that might make some of his actions in the chapter things he might not have remorse over. Also when he is talking about building another orphanage it felt like he was doing what was sociably the correct thing to do when betraying ones country or commiting a crime. At first i thought maybe the nobles had a system of penances for misdeeds, say indulgences for crime. Just something that came to me as i was reading.
I enjoyed reading this and I am looking forward to seeing what happens next.
