The Aetheric Ocean is the great eastern sea of Eryndor, a vast stretch of water where fog hangs low and thick almost year-round. Sailors say the air tastes different there, and that at night the mists glow with faint shifting colours, as if something just beneath the waves is breathing. Beyond its grey horizon lie the Crosswaves, a complex set of wave patterns, and the Shattered Reach, for those stubborn or foolish enough to try for them.
