Looking for Pathologic RP suggestions

I have been thinking about doing a Kingmaker run inspired by the game Pathologic. My MC is a vivisectionist/knife master and is supposed to Daniil Dankovsky.

I usually play as a good aligned character, so this time I want to start out as true neutral and see where it goes.

So what decisions/setups in Kingmakers do you think would fit with Daniil's character? Any particular companions/builds I should focus on? Any particular advisors I should use?
