Gah! Sorry, I just noticed this.

And then the Boy will say its goblins in the forest, or they got captured by trolls in a cave in the hills, or maybe bandits. And then I'll just roll with that. I have a little map I use of the general area, as well as one of the town his guy lives in. That helps frame things. Sometimes he'll just look at the map and want to explore.
Don't stress out over NPC stats, etc. I just use the "Average" stat values form everyone, unless I'm making a boss monster of some sort. And just use the quick NPC creation stuff in the Chronicler's chapter when he's interacting with something that doesn't want to kill him.
You'll have a lot of fun. I've found its a great way to exercise my creative muscles just trying to keep up with his crazy ideas.
