Harlan's World is the only habitable planet in a star system approx. 80 light-years from Earth. It is host to three moons and a series of orbital platforms known colloquially as the Angels. Originally founded by Konrad Harlan and settled by the remnants of a Japanese keiretsu using East European labor, Harlan's World ethnic mix is primarily Slavic and Japanese, and is governed by both the Harlan family in particular and the Protectorate in general.
The world is small for a habitable planet, and its seas, that cover roughly 90% of the planet, slop about unpredictably under the influence of the three moons. The majority of the landmass on the world comprises island chains and archipelagos, the largest of which is the Millsport Archipelago, followed by Kossuth and then New Hokkaido. The length of the year is not stated, but it is said that a year on Harlan's World is longer than a year on Earth.
Originally colonized by an expedition led by Konrad Harlan, whose family would become the leading aristocracy of the planet. Over time, the city of Millsport would become the planetary capital. The planet's economy seems to be dependent on the mining of the metal used for Cortical Stacks. Harlan's World eventually fell into a massive planetary war known as the Unsettlement, led by Quellcrist Falconer and her followers.
