Eos (Cosmoria)

As far as stars go, Eos numbers among the smallest in Cosmoria. At just 200,000 km across, its habitable zone lies a mere two million kilometers from its surface. Under normal circumstances, this star would have a population somewhere in the billions, a mote on the scale of Cosmoria's civilizations. Eos, however, is not a normal star for surrounding it is a megastructure dwarfing nearly all others. This massive structure is a large flat disk orbiting this dwarf star. On this disk reside hundreds of trillions, environments unseen anywhere else, and some of the most influential empires in history.

The gateway from Aylathiya to wider Cosmoria, Eos lies in the center of the civilization of Martial Space. An economic powerhouse: merchants, companies, and governments often use the large structure as a staging ground for their commerce of all kinds. Underneath the trade-friendly orderly surface is an eternal conflict as dozens of factions strive to take advantage of Eos' lucrative position. A gilded world, the guise only occasionally disappears. When it does disappear, however, it disappears with great force, leaving the rest of Cosmoria suffering generation-defining recessions at best.

Nearly every group imaginable takes credit for the creation of Eos, from the Dotsk who have a reputation for building mega-structures, to nationalists in Florathel that claim only the Lareas Alliance could have created the structure. Historians on Eos sometimes credit its creation to Ohko's Civilization, but they just as often credit the First Aeterna Society. Regardless of the origin, it has continually existed for 2 to 4 million years, likely taking much of this time to construct. It is technically unfinished, as a large section of the structure has never been filled in.

The world remained a backwater on the galactic stage until the rise of the Triumvirate Civilization 200,000 years before the present day. This civilization's meteoric rise caused Eos' population to balloon to over a quadrillion by 15,000 BCE. When the Triumvirate fractured as its three leaders went their separate ways, the resulting war caused its population to dip below one trillion, resulting in a galactic recession that has still technically not ended. From then, Eos has continually united and fractured until the modern day, currently existing united under the Greater Martial Consilium.

Structure

Habitable Zones

A mere one million kilometers away from its star lies in the innermost region of Eos. This area, with an average temperature of 500 Celsius, seas of lead are common. In a thin ring around the center, certain areas are hot enough for even silica to begin melting, creating a hellish environment of nearly 2000 celsius. This innermost region is home to the Orcubor and the cooler areas serves as the home to the Atlins.

Further out lies an area that is too hot for liquid water to exist but also too cold for the seas of lead. This area was originally lifeless, however, life from D'Naevium, a similar environment, seized the opportunity to live in this otherwise barren region. Artificial life and self-replicating machines also call the region home, their creators having little motivation to purge the area of them. Besides the Ror Units, few species find this area comfortable.

The largest region by area is that which can sustain liquid water. This area is divided into two parts, the "summer" and "winter" zones. Large seas cover much of this area, sustaining a flourishing ecosystem of mostly carbon-based life. Holding the bulk of the population, industrial capacity, and economic production, this area has historically been the most powerful force in the object's history. The winter area freezes over as Eos wobbles relative to Mili.

Orbiting Bodies

Numerous bodies orbit Eos, many of which are fragments of the object that were broken off of it in its long history. One such planet, Hikari, was a large mass of Eos that had enough mass to collapse into a sphere.
