Chaos (13th Dimension)

The Chaos, or Chaos Sea, is a dangerous environmental phenomenon covering a significant proportion of the world in the 13th Dimension. It was caused by the Fall of Typhon, an event that occured in the distant past, either before, during or after the void century, though the alteration of time incured by the event makes accuracy difficult.

The Chaos manifests itself vissibly as coloured fog, usually silvery or grey. Within it, the fundamental laws of reality are considerably altered, in extreme cases beyond any recognition. This makes travelling through chaos areas extemely dangerous, and has made the task of traversing the New World and Grand Line far harder than it may have been otherwise.
