Kitsune. Those spirits of the oriental world that have as much place in their fables then dragons and such. The mood, humor, lifespan. The manifestation explained. How they feed, on what they feed, and how it affects the enrivonement. The different moods depending on the type. Its rather interesting. I dwelled on for an hour or two and I seriously think something can be done
