Planet Seva Settings
As the title suggests, the bulk of the story takes place on the planet Seva, home of peace, prosperity, and feathers. The settings on the planet happen to be rather diverse, and there is no need to spoil any of that for those who haven't read the book.
The story does take place in other places, most noticeable being our own planet Earth, known throughout Esrevni for its violence, greed, and pretty much all of the negative aspects. (Which of course overlooks the positive, but this is the perspective of completely different civilizations).
As far as the timing goes, the book most likely takes place in recent times (According to the current time line, it is spring 2003). The duration of the story is around a week, but a lot can happen in that time...
