Your are completely fine opting out and...

Manipulating the plot of the characters or trying to prevent them
from meeting any goal, or helping them is perfectly fine.

Remember..Carrion Fields is an open world game and we encourage
Roleplaying, not just Pking. Have fun with it any way you wish.

I would expect if there is a character running around that is say..

An Anathema..That all Imperials are gunning for them.
