A great machine from the stars lands near the Gryphon capital, its origins and cargo unknown. News of this event reaches the ears of Princess Celestia, and decides to personally aid the Gryphon authorities in their investigations. Tagging along is her faithful student, Twilight Sparkle, and an armed contingent of the Royal Guard.

Even before arriving, things seem oddly tense: the Gryphon Queen is being secretive and uncooperative with the Equestrians; Gryphons on the ground are on the edge; people have gone missing; strange black creatures have been sighted within the no-go zone.

What's the secret to the abandoned alien ship? Where has its crew gone to? Is it really deserted?

Enter the horrors of another world...
