Yeah sure, it would be way to clunky for me to respond to everything and I don't want to have to RP every person you come into contact with :P feel free to make up NPC's throughout the RP to interact with, just not any that will really alter the story line by sending you away from the group or doing something too significant. The NPC's that I don't want you to control will most likely be the ones you fight and the important figures like the Baron.
