Looking for an old IF game about escaping a dragon's lair

I was hoping someone could help me out here, or at least find someone else who remembers–I don’t think this game is on the internet anymore, but it’s worth asking.

About 10-15 years ago, I played a short online chatbot-style IF game, I think it was hosted on some university server and was stated as an experiment to explore the genre. In the game, you started out having blundered into an occupied dragon’s lair, and had to talk your way back out of it–the only way to live was to convince the dragon to let you go. I can’t remember the name, but I’d love to find some reference to it again.

A brief walkthrough, if it jogs anyone’s memory:

The dragon’s mate is sick or injured. By asking questions you can learn that she exists, and learn that there is medicine that will help her which your captor is unable to retrieve. You can convince the dragon that you can retrieve it for him, but he does not expect humans to be honorable by default, and you must say “I vow to return”.
