I got this idea from Mordjinn in this other thread. The cards worked so well for Eye for an Eye that I decided to make a set for Winds of Change. These really helped the players keep track of all the NPCs, gave them a handy space for notes, etc.
This set contains cards for all named NPC's in the adventure material. There are also some extra birds, because I wanted to take the bird theme to a whole new level of entertainment, and throw up a bit of a smokescreen for the more important birds. Gehimnis causes strange behavior in our feathered friends!
