Twilight Sparkle embarks on a mission which takes her to Archer III, an untouched planet of the Archer system within the outer rims of the Galactic Equestrian Nation. As an accomplished scientist working for the Royal Equestrian Navy, she will lead a team of mares in the seemingly straight-forward expedition that Princess Celestia and Princess Luna insist is merely a colonization attempt. However, some groups seek to expose something powerful that the Princesses sought to be kept out of the wrong clutches.

Things quickly spin out of control, and the entire Equestrian Nation threatens to erupt into a chaotic struggle for existence.
