For Princess Luna, the evening seems like it will be business as usual, at least until strange lights begin appearing in the darkening sky over Canterlot, amidst other odd goings-on. Unbeknownst to Equestria and the world at large, an ancient and mysterious culture the Earth has not seen in millenia has finally returned after much hijinks and exploration in the cosmos, curious as to what has become of their beloved ball of rock and its unique inhabitants in their long absence.

Now Luna's face to face with jovial hornless minotaurs clad in gear that belongs in an Equestrian sci-fi flick. Maybe Celestia's outlandish claims weren't so outlandish, after all.

Crossover tag due to certain overly obvious references.
