This story is a sequel to The Red Sun Rises: Voyages
Princess Luna has been assassinated. In order to revive her sister, Celestia ventures to the east of Griffonstone. After a 'minor' mishap, she allies with an American fleet to get to the Dominion of Apollo, where an answer may be had.
In her absence, Princess Twilight and Princess Cadence rule Equestria. They keep Crimson Dawn as the military commander because of his effectiveness in achieving victory on the battlefield. What happens while they work could never be expected. It is over the top, even for their enemy, King Sombra, and the Crystal Empire.
As he fights off the Crystal Empire's armies, Colonel Crimson Dawn deals with memories of past wars, past battles. And it's up to the epitomes of friendship to help him get through the flashbacks.
