Ersetu is the home world of the Kishargal and capital world of the Constitutional Dominion of Ersetu. Ersetu is a harsh, unusual world, tidally locked with it's star Kuangirru

The smaller the fire, the closer one must sit in order to stay warm - such is the story of any living world reliant on a red dwarf. Though the smaller size also means trillions of years of stability and no explosion at the end; Ersetu must sit so close to its parent star that gravity ends up acting noticeably different on opposite sides of the planet. Tidal forces have a stronger influence on the day side, griping it over and over, until millennia after its formation, the world nearly ceased to spin.

Though Ersetu does technically still rotate, it is so slow that the nearby red sun stays permanently affixed to it's place in the sky. In this case, a situation that ought to be optimal for the existence of life instead roasts the day side and leaves the night side to freeze. In the twilight, however, between fire and ice, a temperate band of failing to dim light is where the most biodiversity can be found - fighting for what space and energy it can to survive.

This phenomenon also means that, as plate tectonics move the continents around, the day side creates maelstroms when open ocean and deserts when dry land. In this modern epoch it is a sea of storms; clear in the middle, with systems spinning off towards the twilight, building massive depressions as the hot moist air drives into the cooler air further from daylight. With this, sea level is also at one of its historical low points with so much water locked in the atmosphere and night side ice cap.

Ersetu is moderately larger than your average terrestrial planet and has one small moon, Hursamgu. Due to the nature of Ersetu's rotation, the Kishargal had no sense of day and night as most species know it until they settled on one of their moons. Instead, their concept of time, cycles that evolved from the orbit of their moon.


Spanning the western hemisphere of the world, Alba is the largest and most populated continent on Ersetu. Alba is home to the majority of the Kishargal populace and the location of the capital city.


The smallest continent on Ersetu, Dearrsadh is a large island to the north of Alba.


The chain of islands to the far northeastern hemisphere of Ersetu.


The only major land mass on the sun side of Ersetu. Ghalldachd is a windswept, storm battered land of eternal light. While there are those Kishargal who live there, they number very few and are the hardiest of the species.


The third largest continent on the planet, Kiengir is the second most heavily populated, occupying the twilight band in the eastern hemisphere of the planet. Kiengir is notable for it's vast desert.

Planetary Ring

Constructed around the twilight band of Ersetu is the great ring city. The ring allowed the populace of Ersetu who did not wish to travel to other worlds or systems, to grow beyond the confines of the planet. Millions of Kishargal reside in the ring city, along with infrastructure to aid the planet below in power generation, shipping and the growing of food to name a few. Nearly the entire surface of the side of the ring that faces their star, Kuangirru, is lined with massive solar power collectors and banks of storage batteries. These collectors are the primary power source for the ring, though a great deal of the collected energy is sent down to Ersetu through the massive spires that connect the ring to the planet below. Since it's construction, the ring has become an essential power generation facility for the home world, providing the majority of all electrical power to the planet. This has allowed much of the old power generation infrastructure to be dismantled. In addition, the massive farming and ranching complexes built into the ring have all but supplanted farming on the surface of Ersetu, providing the bulk of vegetable and livestock production for the planet below and export to other worlds in the Dominion.

The ring city is primarily reached by sets of massive space elevators built into the 8 towers that support the orbital ring. These massive structure, now millennia old, reach up from the surface of Ersetu and act as much as huge vertical cities as they do support structures.


The capital city of Ersetu and the seat of power of the Constitutional Dominion of Ersetu. Kurumtamtu is an ancient city built on the site of the oldest settlement known to the Kishargal people, the city of Ersumatumtu. For generations, Kurumtamtu stood as a trade hub and center for knowledge and art and the apex of Kishargal society. A sprawling coastal metropolis on the eastern seaboard of the main continent, at it's center is the great harbor, overlooked by the white walls and spires of the castle Dunakkin.


An ancient mountaintop fortress city, Ardcarrik, the fortress of the stars, sits atop one of Ersetu's highest mountain ranges.


One of and the largest of a very few cities on the stormy day side of Ersetu. Ballyagherty was once the wartime stronghold of the followers of Kuangirru, the goddess of life and eternal light. Comprised of a massive and thickly walled castle, the fortress city is forever battered by the winds and rains of the eternal storms that swirl about the day side of Ersetu.


Caenn is a large city in the northern hemisphere of the capital continent, also the site of the second major tower constructed for the orbital ring city. The sprawling metropolis's centerpiece is the massive structure that reaches up to the stars. The lower several kilometers of the tower are part of the city, which has built up around its base and sides. From a distance, the city, ever cloaked in twilight and lit with millions of twinkling lights, looks something like an massive decorated holiday tree.


A desert city to the far east, across the great seas. Cèic was once the farthest outpost of clan Kinnon, a great trading hub for exotic spices and goods and the center point for the great mining expeditions in the era of exploitation. Cèic is still a center of trade on Ersetu and a place where a great many craftsman produce wondrous creations.


Castle on the Eastern Coast of the Alba in the northern territorial claim of Issael. Site of a famous battle of the Ersetuan Civil War where a severely outnumbered Warad troop defended against a Legion of Kinnon armies, and won. Harlaech today is a very small, but bustling, port city home to the Harlaech Docks. Castle Harlaech stands on a nearby height, strategically guarding both the port and the western hillside from its elevated position.


The city of Lann dominates the tiny island in which it shares it's name. Lann was once the capital of a now long forgotten seafaring clan, whose corsairs preyed upon the shipping in the northern seas. Now a major port city, Lann is also home to many of the best civilian shipwrights on Ersetu.


Lharak is where the great orbital ring city began. The first tower was begun here and the city grew around the structure as millions of Kishargal came looking for work. An immense industrial complex grew, and still serves as the largest manufacturing center on Ersetu. The city it's self is massive, climbing miles and miles up the sides of the tower. Lharak is an artificial mountain that claws at the heavens.


A small city in the south seas, built around the base of a dormant volcano. Once notable for frequently having to be rebuilt after rogue storms or volcanic eruption, it is now known for its idyllic sandy beaches and hot springs.


The ancestral capital of clan Kinnon. This coastal city sits upon high white cliffs and surrounds the castle Skye, ancient seat of power of the Kinnons.


Ersetu's lone moon, Hursamgu, is a large body that hosts abundant with life of its own. Some scientists theorize that it was another planet developing in the system's early history whose orbit crossed too close to Ersetu's and was captured by the larger world's gravity well. Hursamgu has a similar atmospheric composition to Ersetu's and is easily habitable by the Kishargal. Hursamgu is a a humid and wet world; its atmosphere thick with fog and clouds all the time. No part of the small world is ever dry or free of condensation or rain. The moon is covered in plant life, mostly a massive ever-growing moss-like plant that stretches across great swaths of the surface. The moon has considerably lower gravity than Ersetu and, unlike it's planet, does have a day-night cycle as it orbits Ersetu. Arrivals on this small companion world were the first to experience the concept of day and night. To this day, that seems unnatural to those Ersetu who do not travel from the surface of the home world.

There are many cities on the surface of Hursamgu now. The Kishargal colonized their moon many thousands of years ago as their first step out into the universe beyond their home body.
