Viridi Greater is the 6th planet of the Hope System in the Ambrosia Galaxy. It was a frozen ice world before being aquaformed the Ambrosia Alliance of United Systems that forms a dual-planet system with its sister world Viridi Lesser.

Overview

Viridi Greater was a frozen dwarf planet located within the outskirts of Hope's inner planetary system.

Originally, Viridi Greater existed as a moon of Acconda. During this period in its history, the world was a temperate oceanic moon with a vast emerald green ocean covering its entire surface, though no known life is thought to have lived there.

It would be aquaformed by the Ambrosia Alliance of United Systems in 10,650 CE, becoming the temperate O-Class world it once was again.

Geography

Its surface is covered in raised ice ridges, small ice dunes, and bumps. As well, massive areas of harden snow created from the freezing of the dwarf planet's ancient atmosphere.

Unlike most oceanaic worlds that have frozen over, Viridi Greater is not an ice shell world. Instead, this layer of ice spreads all the way down to its core.

Viridi Greater forms a dual-planet system with its sister moon, Viridi Lesser. However unlike most dual-planet systems, the two ice worlds are so close in size that they both orbit each other almost perfectly in a wildly chaotic orbit that will eventually make the two crash into each other.

Climate

Viridi exists within the outskirts of Hope's inner planetary system, meaning that it is quite cold. With a frigid temperature of -153 Celsius there was little hopes of being able to be terraformed, Viridi seems to be not worth the effort to colonize as there are better bodies near by, such as Haven and Douma.

However, though terraforming seemed to be off the table, the Ambrosia Alliance of United Systems would make the world at least semi-habitable to humans through the use of: "Aquaforming". They would heat the dwarf planet's icy surface, melting the water-ice while the dwarf planet's gravity would hold onto the water, forming a thick atmosphere. Through the runaway greenhouse effect of this event, the atmosphere would become thick and trap the heat.

However originally, Viridi had a quite hospitable temperature of around three degrees Celsius. Allowing for its native Havenites to live quite comfortably.

History

Viridi Greater formed from the debris of Acconda's planetary formation disk alongside its sister moons in 4,795,900,000 BCE.

As it cooled from its formation, the moon would have its surface covered in a large fresh water ocean encircling the entire moon. And with its newly formed thick ethane atmosphere, it gave the moon a distinctive emerald green coloring.

Viridi Greater would receive its first tenants in the form of the Havenites in 2,489,466,000 BCE, as they would establish massive floating cities across its lunar ocean.

However in 1,600,215,000 BCE, its parent planet would cross into the orbit of Douma, sending it and its sister moon hurtling out of their orbits. Afterwards, the now dwarf planet would begin to have its surface ocean freeze, forming one large ice structure tunneling all the way down to its core, destroying the Havenite colonies that were housed there. The two former moons would remain in gravitational resonance with each other, forming a dual-planet system.

Much later in its history, it would be discovered by the Human Alliance of Ambrosia in 10,265 CE as they entered within its home star system. However due to it being very inhospitable, no colonies would be established there. Until' it was aquaformed in 10,680 CE by the Human Alliance of Ambrosia's successors, the Ambrosia Alliance of United Systems, then many human cities would be spread across the newly created planetary ocean.
