Chaos Vortex

Chaos Vortex (混沌の渦) is a vortex obstructing southward routes in El Phildin.

Background
Heading east from the south of the Medium Mare (内海) lies the Chaos Vortex, which is said to swallow everything in its vicinity. It is situated precisely where the Gagharv converges into the ocean, with rainstorms sweeping over the seas surrounding the vortex due to the Gagharv's turbulent air. As a result, many ships are sunk without ever laying their eyes on the vortex.
