A Lovecraft-Lite story. Starts slightly dark, but turns light soon.

Used as a distraction, an unnumbered amount of humans were let loose on Equestrian soil. As the released try to make sense of both their surroundings and their own now alien bodies, strangely sentient wildlife, talkative yet indecipherable horse-things and unearthly physics of this strange new place, while their former jailer sets out to return them to the prison of flesh they were temporarily released from.

Torn between blending in the alien society anonymously or making their presence known, the former humans must decide whether to become the men or monsters of this new and eerie place.
