This is a world located in the Triangulum galaxy. It’s system consists of a low mass red dwarf with six planets: Three Neptune sized gas giants and two other rocky planets slightly larger than Earth’s moon. It has an atmosphere of 31% oxygen, 67.4% nitrogen and 1.6% methane. At present, the year is 130 local days long with 5 months of 26 days each. In earth rotations however, it’s about 196 days.
The parent star is extremely young; it formed about 1.8 billion years ago, followed by the six major orbiting planets within the next 400 million years. Single celled bacteria emerged in the oceans of Aptia around 900 million years ago, with multicellular life appearing circa 570 million. 484 million years ago, a mass extinction caused by volcanic activity forced some of the sea life to adapt to life on land; a total of 88% of prior species were wiped out. By 100 million BCE, a plethora of land creatures existed, including reddish trees that grow as high as 800 feet (240 meters) known as bloodrods.
23 million years ago, an intelligent creature evolved known as Neopithicus. The Neopithicans had spread to all three major land masses by 16 million BCE, and began using rocks along with sticks from bloodrods as tools around that time. Their Stone Age continued to the present, for now.
By the year 30,000 CE, the Neopithicans began using cooked food and and hunted in families. The first permanent villages were built around 34,000 CE, followed by irragation canals during the rest of the 35th millennium. By 36,000, farm based cities were built along with temples and other buildings. And in 36,034 CE, the first international railroads were built between the tighly packed land masses. Their history after this point has not been fully documented for some unknown reason.
