Mordent

 

Introduction

Mordent is a rugged and challenging world located deep within Omnium space. Known for its harsh environmental conditions and formidable gravity, Mordent stands as a testament to the resilience and adaptability of the Omnium settlers who call it home. Despite its inhospitable nature, the planet serves as a critical industrial and strategic hub within the Omnium, hosting specialized operations and research facilities that thrive under its unique physical conditions.

Geography and Environment

Mordent’s surface is defined by extremes. With a radius of 7,481 kilometers and a gravity of 1.29G, it exerts immense physical strain on all forms of life and infrastructure. Its orbit period of 7.49 years creates prolonged seasons — long, turbulent cycles of storms, dust fronts, and deep freezes. The planet is tidally locked, with one hemisphere trapped in perpetual daylight and the other in endless night. The day side is dominated by hurricane-force winds, radiation exposure, and vast dust plains, while the night side lies beneath glaciers and frozen seas, illuminated by geothermal vents and rare tectonic light plumes.

The mean surface temperature of 259K (-14°C) and an atmospheric pressure of 7.93 atm combine to form a crushing, high-density environment. Human survival requires pressurized suits, reinforced structures, and constant atmospheric regulation. Roughly 31.17% of Mordent’s surface is covered by water and ice, concentrated on the night side and in subterranean reserves. These frozen resources provide both the colony’s lifeline and its industrial backbone, feeding water extraction, metal refining, and chemical synthesis facilities across the twilight zone.

Population and Society

Mordent’s total population numbers only 21,600, spread across several fortified settlements within the twilight band — the narrow strip separating day from night. These communities are heavily shielded from surface conditions and interconnected by underground maglev tunnels that serve as conduits for power, water, and transport. Daily life is governed by discipline and endurance: inhabitants endure intense gravity, oppressive air pressure, and isolation with stoic precision.

Welcome to the Twilight Run Universe

By the twenty-third century, humanity had long since left Earth behind. Colonies stretched across dozens of star systems, and Terrans believed themselves an expansive and unchallenged civilization. For a time, it seemed nothing could slow their rise.

 

That belief ended when the Anirans and the Cetians revealed themselves. They were not strangers from distant space, but ancient branches of humanity that had grown in parallel, hidden from Terran sight. The Anirans, guardians of harmony and tradition, and the Cetians, architects of survival and resilience, unveiled a history far deeper than Earth had ever known. Their arrival transformed Terran science, politics, and identity, stirring awe, doubt, and unease.

 

To preserve peace, the great powers of Earth joined with the Cetian Consortium and the Aniran Omnium to form the Council of the Core and the Mutual Defense Force. It was a first attempt at true interstellar unity, yet suspicion still lingered. Centuries of distance had left wounds not easily healed.

 

And beyond the mapped stars, something else is stirring. Rumors tell of a hostile presence waiting in the dark, silent and watching.

 

As alliances strain and rivalries return, the three branches of humanity face a choice. Stand together against what lies beyond, or fall divided before it.

 

Twilight Run is a Universe of wonders, curiosity, survival, diplomacy, and the unsettling truth that humanity is not alone—and may not be ready.
