Don't worry, starting with just my FC first, but since I'm trying to create an event that's happening in the world, its always nice to have people outside the FC knowing. For example, when you need to talk to a flames officer, its one thing to talk to another NPC run by the storyteller, another to talk to another player who's running a flames officer.
If you always do what you've always done, you'll only know what you've always known. And that's boring.
