We haven't actually started yet. We are still making characters and it will be a couple weeks before we begin.
The primary reason I am using Non-scaling NPCs is to simulate the array of low, mid, high and vast power of the opposing regents. If you are not familiar with Birthright, there are several ancient, evil and incredibly powerful beings that rule some of the realms. My players are the kinds of people who would march into their realm with an army and challenge them on Day 1 since Fantasy Craft normally scales all encounters. I just wanted to make clear up front that this would be a Bad Idea (tm).
No we wouldn't... not that we couldn't, but it's more fun enslaving their countries first.

Actually I'm very surpised at our current party make up. There's nary a dedicated fighter among us except me. I have a feeling my pech.. er halfling... is going to be tanking for the party. I may need to make adjustments on my character's plans.
