Two months have passed since the starship carrying evacuees from Earth crashed on Equus. All that were on-board have recovered from their injuries, and the starship has been repaired. At the same time, Twilight has ordered Flurry Heart and the Young Six to lead Equestria's top soldiers in a defensive battle to assist the Inklings, Octarians, and Salmonlings in securing a peace treaty to settle the conflict with the humans who have returned from deep underwater. Will this mission succeed?
