There are a lot of stupid and terrible rumors in Equestria (and beyond) about flying city Starspire and his citizens night pegasi (batponies or thestrals).
For example, that night ponies are militarists and religious fanatics who drink blood, kidnapping foals, and in general responsible for half of the problems of poor ponies.
It's time to disprove them, by telling a story about three friends, living in time before the events of the original show for more, than a thousand years.
