The Equestrian Royal Navy has... Declined. What used to be flotillas upon flotillas of mighty vessels is now a collection of small sailboats, albeit in excellent repair and with all the conveniences and tech of modern Equestrian sailing.
However, when a threat to Equestria rears its head, Twilight Sparkle - along with Equestria's most magically-talented mares - must embark on an ocean-bound adventure to save the land!
...This can only go well.
