Hello I am new to the forums so I do hope this is in the correct location.
I am currently writing out an investigation that my party will be going through at sometime. A little background information is needed on both the adventure and the party.
Party:
1. They are very combat oriented and don't normally think of investigating anything unless it is spoon fed to them from the start through me.
2. Everything CAN be solved by violence.
3. The party is made of Sister of Battle, Tech-Priest, Psyker, and a Guardsman, and an Assassin. There is a npc adept that I use to help them anywhere non-combat wise, but I don't want the npc to be the only way they advance.
Campaign:
1. An Adeptus Arbites precinct house was bombed and they are sent to investigate why it happened.
2. Through the investigation, they will have to confront a bishop about the Frateris Militia possibly being behind it. The Arbites will have been doing an investigation alongside the party, and so will burst in during the party's "interrogation" of the bishop. Through means I have yet not fully thought out, the Arbites and the Militia with the bishop will get into a scuffle and shots will be fired.
Now to the question: Would a Sister of Battle be obligated by Imperial Creed/Moral Duty/etc to help protect the Bishop from the Arbiters? Especially if he calls upon the faithful to protect him from the heathens.
The Arbites are not corrupted, just doing what they see as right to avenge the death of several officers.
I am trying to change the tone of the party to be less combat oriented, which I will admit I have been feeding from the first couple of sessions.
