Arpeia (Planet)

Arpeia is a planet located in the Foggy Way, which is the largest galaxy in the Neighbor Group. The Neighbor Group is part of the Polefi Supercluster of galaxies. The Foggy Way is a large spiral galaxy, and Arpeia is located in one of the spiral arms (called the Siroyam Arm) which lies about two-thirds of the way out from the galactic center. Here, it is part of the Mavar System, which consists of 11 planets, numerous comets, asteroids, and dwarf planets that orbit the star named Mav. Arpeia is the 4th planet from Mav and is orbited by two moons named Golma and Mirat.

Arpeia is composed of six main continents. From west to east on the map, these are Granheim, Cagri, Tarepas, Okirias to the north, Kretila to the south, and the uninhabited continent of the Mertsodia at planet's southern pole. Arpeia's major oceans are the Bolic, Soldak, Makiric, Sundar, and Trolrem. Other major bodies of water include the Dolm Sea, the Brafen Sea, Lake Elemos, the Ashen Sea, Lake Kolv, and the South Granish Sea.

Planetary History
Arpeia’s existence as a planet is divided into four Geological Epochs: the Evirean, Ankifean, Priavivic, the Kotenbavivic, which is the current era.

Life on Arpeia traces back to billions of years in the past. Arpeia as a planetary mass formed approximately 4.8 billion years ago, and evidence suggests life emerged approximately 3.7 BYA. The similarities in life on Arpeia indicate that species evolved from a universal common ancestor and underwent significant divergence across varied periods of time.

Primordial soup of coexisting microorganisms were the source of early life during the Ankifean Epoch. In these habitats, much of early evolution and development of life occurred. Photosynthesis, which evolved approximately 3.6 BYA, caused an oxygen buildup in the atmosphere, with led to the planet to gradually shift from a reducing atmosphere to an oxidizing one. As a consequence of the oxidation, many early species died out, and the remaining bacterial life forms served as a basis for future multicellular lifeforms.

After many years of new dominant lifeforms emerging and going extinct, mammals began to take their place as the new ruling class of animals. Eventually, a bipedal species related to the rest of the Great Apes learned the use of tools, collective learning, and many other foundational elements of intelligence. These were the humans, and they would make their mark across the entire world.

Humanity on Arpeia
Anatomically modern humans on Arpeia arose about 300,000 years ago. These humans spread across the planet, settling on every major continent by at least 50,000 years before the Great Collapse. The advent of agriculture around 10,000 years BGC resulted in the development of sedentary societies, giving way to the rise of civilization and eventually the modern, technologically advanced, and interconnected world of nations.

The most recent piece of land discovered by humans was the island of Turboria in 1901. Due to its proximity to Mertsodia, the island hosts a small research station.
