Sea of a Thousand Currents

The largest body of freshwater on the planet. The sea rises and falls each day, bringing all manner of sea life to the regions surrounding it, providing sustenance to everything along its shore. So vast is this sea, that the shorebound observer would see only the faint silhouette of the surrounding lands on the horizon. It is beneath this colossal well that House Nautica dwell, traversing the deeps and sharing visions of the futures they foresee.

## The Spiral Keep

Depth: 550 metres below sea-level.

An immense conch, settled and pressed into the very bottom of the seabed. The pressure here is so intense, that the integrity of this mysterious structure is pressed to its limit. Only with the magical power of House Nautica's leaders does the Keep stand pristine. The messages from this coil are carried to the surface by way of billions of tiny bubbles.

## Redrock Cove

The seemingly tranquil beaches of Redrock Cove hold a plethora of resources and unique wildlife that the sea usually shelters beneath the surf. Creatures from all around come to plunder or protect these shores.

Housing: None.

A strip of land between the cliffs of The Shifting Expanse and Sea, Redrock Cove almost completely disappears beneath the waves at high tide. The waters retreat again in the morning, revealing washed up shellfish and sea-plants. Animals and birds patrol the shallows, all seaking easy pickings brought by the movements of the tides.

## Tsunami Flats

Temperature Range: 20.5°C - 30.3°C

A becalmed coastal stretch of shoals and giant tidal pools. House Nautica occupy the pools, burrowing into the loamy sand and shaping half-submerged underwater caves with their small magics. Sustenance, in the form of amphibious reptiles and fish, is abundant. Although seemingly a frontier, it is at these shores that House Nautica is most able to protect their charges, employing tidal wave defenses to menace away aggressors.

Housing: Abundant

A home in the Tsunami Flats is built besides, or within, the many tidal pools in the area. Totally submerged in the evening, the entrance are sealed off with a giant bubble of air, granting control of the water levels inside and allowing all creatures to live here. Pushing through the half-submerged bouncy, oddly strong bubble leads to caves that vary in size, but share the firm, fine-grained floors decorated by natural seashells and embeded corals. The sunlight that shines through the water casts shiny, undulating shadows on the smooth, sandy walls. With easy access to freshwater pools and hot springs in the winter, this is a luxury home for those who don't mind getting their feet wet.

## Fishspine Reef

Depth: 0 - 80m

Temperature Range: 26.5°C - 32°C

The Fishspine contains coral reefs sprawling over a large area, with small cave systems that can be found beneath the surface. The most shallow area of the sea, there are few environmental hazards and no predators call this biome home.

    The coral here roots deep into the dried marrow of gargantuan bones left behind from an ancient battle in a forgotten era. Whether these remains are of monstrous fish, beasts of yore, or something completely other, the Fishspine is crowded by a lost history, sunken artifacts, and drowned spirits.

Housing: Plenty

The Fishpine Reef is a highly active home, with fasinating sea creatures constantly swimming back and fro. Houses are build along hollow, cone-like structures. On the outside, there can be many ridges or coral that easily lend to the hollowing and construction of a house within the coral's bony structure. Here, shools of fish are a common sight, and the water is filled with the crowing of sea-creatures. The shallow water means much the light of the sun illuminates the area easily, and people living on the outside of these long, coral spines can create for themselves a small, underwater balcony to raise vibrant sea plants.

An alternative building site is to construct their house within the hollow of these giant cones. Here, the water is much more peaceful, with the majority of the cacophy and bustling sea-life blocked out by the thick, coral walls. A dim ambience, artificial lighting is often a substitute here, as far less sunlight peak out from the cracks and gaps along the shelf. Only smaller fish tend to dart through these pipes, and many come within for its shelter to rest. And so, these are the more favoured building sites for those who prefer their quiet.

Leaving the house requires a swim, so always have a scuba suit handy. Alternatively, simply encase yourself in an airbubble, and travel unimpeded through the waves.

## Kelp Beds

Depth: 0 - 160m

The Kelp Beds is characterized by the abundance of Creepvines, and possesses a distinct greenish hue in the water.

It is located at medium-shallow depths, and is home to many passive life forms, with some exceptions. The seabed is mostly mossy and sandy, with the terrain being comprised of grassy knolls and arches, sometimes showing entrances to small cavern systems. There are many canyons to be found in these beds.

Housing: None

The Kelp Beds and the Fishspine Reef are the most productive places in the Sea. They are home to an abundance of creatures and plants, making them a great producers of natural resources. The Kelp Beds is home to some larger predators, and is currently not inhabited by House Nautica, remaining a public, and mostly wild space.

## Leviathan Trench

Depth: 180 - 550m

Temperature Range: 13.4°C - 14.3°C

The deepest part of the world. The sea beneath the sea is a treacherous and savage place possessing of an unforgiving undertow and precious little light. Many wonders are said to exist here - more relics of prehistory - shrouded, even from House Nautica's gaze, by a silty, unbroken twilight occupied by alien fish, and far worse. It is in the safety of the cliff faces that people dig their homes, and into the unknown that their bravest dare dive.

The Leviathan Trench continues deep beneath the earth, with one end leading into the Inactive Lava Zone and the other to the Lost River. Small openings along the walls leads to a large cavern with a dense population of huge, translucent, purple Jellyshrooms, along with structures such as stalactites and stalagmites.

Housing: Common

Although the deepest parts reachable from this trench are around two kilometres underwater, The local area only drops down about 500 metres, and only inhabited for the first 300, with the Spiral Keep being the only exception. These two, long walls make for excellent construction sites, and there are plenty of homes carved out here. The sea-floor first gives way to this fissure at 180 metres down, and many homes are created just along the rockface here closer to the surface. However, some choose to live farther down, with the last of the homes speckling away at 300m below the surface.

Homes here are easily the largest of the Sea of a Thousand Currents, as there is a large amount of space avaliable, extending in all directions. But the trench's depth means that little to no sunlight touches its walls, so artifical lighting is required. Bioluminescent fauna and flora are common, and provide an eerie, but beautiful backdrop. Terrestrial creatures require a special suit to travel without health consequences at these depths, which House Nautica is happy to provide. A special mouthpiece draws oxygen directly from the water, removing any need for O2 tanks. Never brigher than twilight and always pink, this place is not for everyone. But for the nocturnal, or those who just enjoy such an atmousphere, the Leviathan Trench makes for a mysterious and grand locale.

## Grassy Plateaus

Depth: 50 - 170m

Temperature Range: 19°C - 27.2°C

Grassy Plateaus are characterized by large, pillar-like structures seemingly created from water current erosion, smooth marine plains, and sandy terrain almost completely carpeted with Blood Grass, giving the Grassy Plateaus their distinctive name.

Housing: None
