A pink mare with a light blue mane wakes up in a dark and unfamiliar room, unable to remember anything. As far as she can tell, she is alone.

Soon however, a strange blue-ish gray pony with green, prehensile hair shows up, claiming to be the dark side of the pink mare.

On a dare, a stallion goes into the Everfree Forest at night. After getting hurt, he finds a strange monster that barely resembles a pony. What it does next though is truly stranger.
