The princesses of Equestria are imprisoned and their land sealed. A librarian discovers a book that transports him to their world and it is up to him to discover why they were imprisoned, who imprisoned them and ultimately, free them.
This is an alternate universe of Mister Citadel's “The Mare Who Wants a Human Child”. This is another what-if scenario. Thanks to Flint Sparks for suggesting changes.
Due to Mystquestria being unpublished, this story will be on hiatus until further notice.
