The vessels of the Scarlet Brotherhood hold complete dominion here - in the Densac Gulf, Azure Sea, and Jerlea Bay. While peace allows traders to sail these waters from the north, few take the chance. The Azure Sea has always had a plentiful share of sea monsters, and most traders used to stick to the coasts of the Iron League states, but monsters seem to be more common there now (unless the ships are those of the Brotherhood, strangely enough). Kraken and coastal sea lions are among the hazards of the Azure and Jerlea Bay, and rumors of morkoths laired around the Olman Islands are a deterrent to travel in the Densac Gulf. The Gulf itself is said to open into a vast ocean stretching well into Lower Oerik, but its waters are unmapped beyond northern Amedio.

The Scarlet Brotherhood has by no means subjugated all of Amedio. Along its coastline and small offshore islands, pirated prove as irksome a threat to Brotherhood ships as they previously did to those of other nations. Some of these pirates are said to be assisted by weather-controlling magic, and to use arrows coated in paralyzing alkaloid poisons from the jungles.

The western half of the Azure Sea is also known to be infested with great swathes of seaweeds that slow ships and render the air foul and noxious, in addition to concealing monsters such as merrow and scrags.
