Near the end of the game Skies of Arcadia, you'll find a Valuan ship hanging around what's left of the Valuan capital. This isn't any ordinary vessel; the ship is a Valuan Spectre -class Spellship captained by Valua's most prominent mages.
In reality, these vessels don't actually take the fight to a canyon. Obviously, I embellished by setting the ships in the crags of the Valuan continent. It's kind of like the Beggar's Canyon race, except these two are taking potshots at one another whilst racing.
