The Cutie Mark Crusaders are a curious bunch of fillies. That curiosity leads them to learn more about the strange realm where Clip, the friendly eldritch abomination, came from. And that leads them into an adventure to save their mentors (and Discord) from the clutches of the horrific creatures that dwell outside our reality.
An outsider looks for friendship and happiness among the citizens of Ponyville.
In the aftermath of Clip the friendly eldritch horror's visit to Equestria, the Cutie Mark Crusaders are drawn into a quest to save the Mane Six--and the universe--from the creeping madness of the nether realms.
