Rasen Kaikyo
“Roughly translated as "The Winding Straight," this part of the Ruby Sea is known for its treacherous currents. Some say the name is far more apt than outsiders might realize, given the many parties that have a vested interest in the region, and how difficult it can be to avoid running afoul of them all.
— In-game description
Rasen Kaikyo is an area in The Ruby Sea.
Landmarks
The Ruby Price
By order of the bakufu, Suenokuni brought earth and stone from the mainland to construct this fortification atop a natural reef. Arrayed with countless cannons, it serves as a defensive outpost against foreign invaders. Those who maintain it must serve for three years before they are permitted to return home.
Barrier Isle
This small island marks the border of Hingashi's territorial claim. Nevertheless, the fishermen of Isari are frequently seen in the surrounding waters. While these incursions are somewhat tolerated, larger foreign vessels sighted in the vicinity of the island may be warned off by cannon fire from the Ruby Price.
Sakazuki
Its name meaning "goblet," this island is said to be the birthplace of the Confederacy, where rival pirates first toasted as brothers and pledged themselves to a common cause. Today it remains an important outpost, constantly garrisoned by sharp-eyed guards who keep watch for vessels that sail the Ruby Sea.
Hells' Lid
Day and night, the volcano on this island spews ash into the air and lava into the sea. By all accounts, it has always been active, hence its name and an ancient tale which tells of oni that once lived beneath its surface, until the legendary hero Tenzen and the Four Lords drove them into the sea.
The Isle of Bekko
Though the isle is within Kojin territory, they themselves consider the name inauspicious, as it refers to the shells of sea tortoises—for which the creatures are hunted. Of course, other peoples harbor no such superstitions, and will use it freely even in the presence of a Kojin.
Onokoro
Legend has it that when the kami first descended from their celestial realm they came to Onokoro, and there built Heaven-on-High. Though the island and the tower are regarded as sacred by some, the Confederates who now call it home do not share their beliefs.
Crick
For the longest time, folk gave these shores a wide berth for fear of the kami, who they believed erected the enigmatic tower known as Heaven-on-High. The pirates of the Confederacy harbored no such fears, however, and one day they claimed the land for their own and established an outpost.
Heaven-on-High
A slender tower of stone stacked to impossible heights, seemingly piercing the very heavens. Aside from a Far eastern myth that attributes its creation to the kami, little is known about the structure. During a time of war, audacous pirates of the Confederacy made landfall and claimed the spot for their own.
Ten-thousand-year Pine
As the name suggests, it is believed that this tree has lived for more than ten thousand years. Of course, there is no reliable way to ascertain the age of the tree, and all that can be said with certainty is that it is older than anyone can remember.
Quickscape Pier
Even the most valiant pirate must be prepared to beat a hasty retreat, and it is for that reason this pier was initially constructed. These days it is mostly used for the inspection and maintenance of Confederate vessels.
Shoal Rock
One of many isles that pepper the Ruby Sea, hemmed in to the north by an enormous circular formation of coral whereupon the Confederacy established an outpost. According to Hingan historians, the isle was formed of magma that spewed forth from Hells' Lid.
The Coral Banquet
This large wooden platform built atop the reef is primarily utilized as a lookout post. From here, Confederate sentries maintain a constant vigil to ensure that they are not caught unawares by invading forces from the north.
Tamamizu
An underwater village founded by the peaceful Kojin of the Blue. Though the Kojin are able to survive for long periods without air, they do not possess gills like the Sahagin. So it was that they developed magicks that allowed them to create an immense bubble of air within which to dwell.
Sui-no-Sato
In the distant past, a group of Raen were driven from their homeland by the fires of war, and sought refuge beneath the sea with the aid of the Kojin. Together, they built what would become Sui-no-Sato. For fear of being forced to flee again, however, they make every effort to avoid outside contact, and so little is known about their society.
The Kobayashi Maru
This Hingan vessel was caugth in a terrible storm which damaged its rudder and set it adrift in the Ruby Sea, until the currents delivered it into Confederate waters. Spying the prize, the pirates sent their ships to demand the Ruby Tithe, and when the captain refused, the Kobayashi Maru was summarily sunk.
Saibai Cavern
One of many caves beneath the waters of the Ruby Sea, it is named for its abundance of shellfish which are regularly harvested by the people of Sui-no-Sato.
Exile
Kagami, a Kojin sage, once called this cavern home. Believing her reflection to be another being with her own thoughts and dreams, she quit Tamamizu and resolved to live apart from her doppelganger.
The Anemone Gardens
This vibrant colony of anemones is highly prized by the Kojin, who harvest the plant-like creatures for medicinal purposes.
The Adventure
This Lominsan vessel was commissioned by an Ul'dahn merchant who sought to conduct business in Kugane, but never reached his destination. Though the circumstances surrounding the ship's sinking are unclear, a surviving sailor claims that vengeful spirits of the sea were responsible.
