The farther east one goes across the Ocean of Glass, the colder and drier the air becomes. Modern scholars have struggled to understand this phenomenon, but to no avail. If one travels far enough, the sea currents all change, drawing east, just as all winds begin to draw in the same direction. Myths persist, however, of something greater, an ancient devouring evil detailed in the legends of the barbarian savages who line among the isles of the Glass Ocean. The legends tell of a voracious creature, a great demon trying to draw the entire world into its maw. An expedition sent during the Star Dynasty to discover the truth of these legends never returned and was presumed lost at sea.
