Does Pestico (of Pestico's Dolls and Figurines) figure into CotCT at any point in later volumes? I've been thinking of having him get involved (to his detriment) with the party's little war with Gaedrun Lamm in my game (Lamm got away and has been Up To No Good ever since), but don't want to accidentally break anything if he's important later.
Pestico doesn't feature in the AP, so you can do what you like without breaking the upcoming.
Well, that's great news for me! (Bad news for Pestico though. Oh well, if you're going to mess with the plotline, you have to break a few NPCs along the way.)
