For a while I've been thinking about a Agent that can be interacted with during the game. This interaction could be a simple dialog or a quest. This project I'm working on aims to help the game designer to create dynamic and procedural quest or dialogues, once the Agent has some information about itself to answer the player (it's name, it's age, what it's doing...).Please read the README, take a look at the example and see if this project is somewhat helpful.
