Very cool and thematic! I will definitely be adding this to my tool belt. I noticed that the Silence, Frame, and Entrench Orders on page 6 all have identical descriptions.
I also noticed that there are multiple abilities that have mismatched mechanics, such stating that a Sin's next action is Hard when CAIN opponents do not make actions and are not affected by Hard. Similarly there are abilities that apply Stress to Sins, which do not take stress.
