There have been several disappearances over the years in Ponyville.
Ponies have gone missing, but strangely, they've always come back
after several months and have no recollection of what happened.

One detective has set herself the goal to solve the mystery.

Note: This story does follow an arch and will not be needlessly padded for 500k+ words.

Due to overpopulation, Princess Celestia has decided to start putting forth an effort to find a new place to call home. She has called upon five ponies to go out and venture into an unknown world. Under the command of one pony, the entire team coordinates to find what lies beyond the portal and if their population can survive in the unique climate.
