Region 11 - Klau'ead Pyue'ea'oed

Spoiler: Geography

Show

The region is part of the wider area nicknamed "the Blue North" by the Lojanese after the color of its waters, which is effected by the lack of contaminants and a seabed covered almost entirely by dead coral with a high albedo. The coral - dead and living - rather than rocks or the like, shapes the landscape, forming great sloping terraces.

The first few Lojanese expeditions trying establish a presence in region 11, although well-equipped, had been stymied and thrown into utter disorder by the near-impossibility of auditory communication. Having trained to communicate through alternate means and developed tools for measuring the distortion of sound, the explorers returned.

After exhaustive experiments that left more than a few members with tinnitus, they determined a clade of endemic plankton species to be the cause. The plankton absorbs the energy of sound with endothermic chemical reactions and uses the gathered energy for its movement and metabolism with exothermic reactions.

This phenomenon occurs in the entire region and is called the Silence by the locals - those among them who have visited other regions to be able to contrast it with normal conditions.

The colonies of the Lojanese and the Auros, respectively named Sau'eazhan and Kalo, are situated in the south, where a hospitable valley has enticed both peoples. Rivalry between the colonies has acquired a long-lasting character. Children pick fights with those from the other town, and adults have only harsh words for the neighbors. On the other hand, trade and cultural exchange has been inevitable, and the smaller, newer settlements are often populated diversely, without any enmity between the inhabitants.

Export: Sapcoral
The corals of the region consume many nutrients by filtering the water and slowly dissolving corpses and detritus that falls from above, in order to grow bulbs ranging in color from orange to purple filled with delicious nectar, by far the most accessible source of food in the region. However, about one-quarter of the bulbs, depending on the species, are filled with sticky sap instead, which rapidly expands due to the pressure inside the bulb and entraps any would-be feeder. The coral consumes the corpse to recoup the costs of growing the bulbs and the cycle continues. The two types of bulbs look identical until the membrane breaks. Which bulb contains what is determined by the shuffling of chromosomes in the one parent cell from which the bulb grows.
The probability of deadly bulbs is determined by evolution. Too great, and fish evolve not to try their luck. Too small, and the coral expends more energy than it consumes.
The sap is dyed a very bright, water-resistant color, but as it is extremely sticky, it must be mixed with some sort of powder or sand to weaken the glue if you ever want to remove the color.

Desired import: Fibers
Although the corals and the seafloor provide a cornucopia of food and building materials, there are scarce furred inhabitants or kelp from which fibers for tools could be extracted.

HS1: Ancient Hut
It is a small, approximately conical bamboo dwelling that has always been there. It is inhabited by the greatest of sages in Klau'ead Pyue'ea'oed. When the sage dies, another moves in. In exchange for being given porridge by the people, they spend all their time studying technology, learning magic and conversing with the gods in order to answer all questions asked.
