History and Background

In YE 41, when the Motoyoshi Clan returned to the Yugumo Cluster, it was decided by Ketsurui-Motoyoshi Katsuko that the clan would invest in the recovery and restoration of the region. The Yugumo Corporation absorbed many companies that had suffered hardship after the Second Mishhuvurthyar War and set out to put people to work and restore the economy.

It was decided later that year, that further investment would need to be made in the local economy. In YE 42 it was proposed that a Ge-H1-7A - Kōdaina Minato-Class Orbital Installation would help boost trade and economic growth. The development of the station took a massive investment from the Motoyoshi Clan, Yugumo Corporation, local governments and the Yamatai Star Empire. The Yugumo Corporation approached the Tamahagane Corporation and started the process of constructing the station in early YE 42.5)

The original plan had the station set to be finished by the end of YE 42, but due to supply shortages attributed to the Kuvexian War, the station would not be completed until early YE 43.

In YE 44, it was decided by Ketsurui-Motoyoshi Katsuko that through modifications such as the addition of experimental Yumeoibito Hyperspace Fold Drive drives developed at Nemesis Bastion, that Port Jiyuu would become a colony platform for the Colonization Initiative Alliance fleet.6)

A city known for its landscapes; lush gardens and crystal blue waterways. It is a feat of engineering and a vibrant living city where people live, work, and play. The city is divided into five prefectures with Asagumo-jo in the center.

Asagumo City is a marvel of Yamataian ingenuity and architecture. It captures elements from both Tokyo and Kyoto.


Asagumo-jo is the private palace residence of the Motoyoshi Clan on Port Jiyuu. It is located at the very center of Asagumo City and was constructed in YE 43.
