Exa

Exa was the origin of the Exans and the birthplace of the Intergalactic Empire, converted into a Planetoid Warship known as the Star Palace, and destroyed at the end of the Trans-Galactic War.

Overview
Exa was the fourth world from the star of the Regen System, originating in the Immateriax Galaxy. After being converted into a terracity, its size was increased far beyond its original diameter. Located at a hyperspace nexus, the planet was a Weave hole, being completely devoid of magic. After being built into the Star Palace, the original planet no longer existed. Its day lasted 45 Terran hours, but dark clouds in its atmosphere made the planet perpetually grey and dark.

Geography
Exa's original geography usually consisted of mountains and plains of black rocks, with most of its surface dominated by grey oceans. Due to the dark and discolored appearance of soil, rocks, water, and other natural formations, the entire planet appeared grey from orbit.

Urban layout
The first cities on Exa were massive, consisting of imposing and often monolithic structures. Megacities were structured to be both living areas and factories for technology. Exan architecture was built to accommodate their species' large size. As a terracity, the planet became even more militarized, with very little actual residences, replaced with military barracks, power plants, defense armaments, and soon, an artificial star as its core, Exa now ballooned far beyond its original size. As the Star Palace, Exa bore somewhat of a resemblance to a flying saucer, with what appeared to be artificial rings and what appeared to be a city on its north pole, with a massive cannon visible on its northern hemisphere.

Environment
The general environment of Exa was cold across the planet, with a toxic atmosphere that would prove quickly lethal to Humans. The climate would have very little variations across the planet, although the temperatures were known to get especially frigid across most of the planet, especially the poles, at the beginning and end of the planet's year. The atmospheric composition was utilized for the Star Palace's artificial atmosphere generators.

Citizens
The first and only true citizens of Exa are the Exans themselves, although Imperial soldiers and commanders of various species were allowed to stay on Exa once it became the Star Palace. The general demonym for Exa remains "Exan," like the native species.

Native species
The only native sapient species on Exa are the Exans, a species of massive, hyper-intelligent cephalopodic non-humanoid beings. After becoming amphibious, the Exans managed to create oversized technologies that allowed them to build smaller and more intricately, as their massive forms previously made such things near-impossible. Exans are feared and hated across galaxy clusters for their imperialism, conquest, and intergalactic genocides.

Flora
Little is known of Exan flora, as no known specimen survived the terracity conversion. However, one species of flora present in old Exan architecture ornaments was a skeletal tree-like organism.

Fauna
Like Exan flora, native Exan fauna is nearly extinct, but was known to consist of lifeforms that were either very bulky or very spindly due to their planet's low gravity. Oceans were populated by mostly bulky creatures of great sizes, such as the Exans themselves and even larger creatures, while land creatures were more often tall and lanky. The only known specimen of Exan fauna to survive after the Trans-Galactic War is an aquatic species known as Roundfish, which bear a great resemblance to a Terran pufferfish, but is perpetually "puffed," its round body being filled with meat and organs rather than water or air.

Government and politics
Exa had always been dominated by monarchies, most apparent with the Intergalactic Empire, an authoritarian cyberocratic state, collecting and controlling information on the planet's populace and workings. Due to the computing aspect of operating a cyberocractic state, top leadership was always handled by cyborg or digitized Exans, operating militaristic policies and controlling data. When Exa was converted to the Star Palace, it was ruled directly by the Intergalactic Emperor, and became a military establishment, although Imperial ministries were still based within the Star Palace. Dissent was always swiftly punished, soon outlawed under the Empire, pushing a more totalitarian policy.

Military
Exa was the original main command of the incredibly formidable Imperial military, with a dedicated division of royal guards assigned to especially important government offices across the planet. Imperial fleets and planetary divisions were known to be stationed and deployed from Exa, activities which increased drastically after the conversion to the Star Palace.

Law Enforcement
Exa's law enforcement was traditionally militarized, handled by dedicated squadrons under Imperial rule, and the need for a law enforcement agency became obsolete once the planet became a Planetoid Warship.

Public Works
Prior to conversion to the Star Palace, Exa was dominated by towering megacities, with Exans populating only select buildings, with all other buildings being factories, utility plants, or military establishments. It operated like most terracities, with almost all products being recyclable or non-disposable, although almost all transportation was public, with private transportation being reserved for top military officials. Structures and hoverlanes were built to be quite large in order to accommodate the large sizes of the Exans. All public works assets were absorbed into the Star Palace, often repurposed or removed as the world expanded.

Economics
Prior to conversion to the Star Palace, Exa's economy was built off of its manufacturing of advanced technology, and of all the wealth taken from the worlds it conquered. However, the planet's economy soon became second to its military-industrial complex, and was practically eliminated from the surface when the planet became entirely militarized.
