Water Wall

the rough waves that destroy ships in the ocean to the northwest of Mizyak. The water surges out from Adroa, making it unreachable.
  As one approaches the far northwest, the horizon begins to blur, consumed by the shimmering and roaring Water Wall. A towering spectacle of cascading torrents, it serves as an impassable barrier, its waters crashing down with such force that they emanate an almost musical resonance. The magic infused within casts an ethereal glow, making it appear as if the sea itself has risen to defy the sky. Those who attempt to breach it find their vessels repelled, ensuring that the mysteries of the far western seas remain elusive.
  It is said the pulsing waves of this pillar that cause the waves all around the world to flow.
