- A travelling teacher in a world falling apart.
- The teachers are more than just people who teach children in classes. They are a group dedicated to rebuilding society by retraining the way people think.

- "Hannah" is one of the few teachers who have travelled out into "the wilds" away from the normal civilisation and became the "headteacher" of a zone that had previously had no teachers at all.
