In a world consisting of numerous isles, a young hero from the Astora
Isle encounters the adventurer Kyle and follows him on an expedition on
the isle. They meet a mysterious girl named Iris and a talking white
cat, and together they make their way to the isle's ruins, where they
find a flying island. Kyle becomes consumed by darkness there, and the
party resolves to travel to the ends of the world on the flying island
in order to find the seven "Great Runes", following Kyle's words before
he disappeared.
