The Equestrian Ministry of Nature keeps a statistic - the census of monsters. It is used for a lot of other private and government decisions, like calculating insurance premiums, garrison sizes and marking of natural preserves. Yet, the data for this statistic has never in the ministry's history properly and fully collected, due to lack of volunteers mentally and physically able to make the survey.
One pony from a tribe that had for centuries been banished from Equestria tries to change that.

More character tags shall be added as the story progresses.
