Solo

Solo, also known as Logo Dau to the Buff Clan, is an Earth-like planet home to a Terran colony at Point A-7 in the Andromeda Galaxy. It is orbited by two moons. Solo was where the Sixth Civilization machines Ideon and the Solo Ship were excavated, and where humanity and the Buff Clan made first contact. The colony became a flashpoint of long, drawn-out conflict between the Solo colonists and the Buff Clan, and the planet was quickly abandoned after this.

History
Eons before, Solo was used by the Sixth Civilization at some point, as they disappeared and the Ideon and Solo Ship were left behind there.

Terran colonists eventually found and colonized Solo, managing to build at least a city named New Lopia, which also housed an airport for any future colonists to land. At least two waves of immigrants managed to successfully settle down before the colony was abandoned.

Six months prior to the Buff Clan encounter, a scientific excavation team discovered the existence of the Sixth Civilization with the Ideon and the Solo Ship. The military eventually got wind of the excavation and the soldier, Bes Jordan attempted to seize their research. The colony was abandoned by the Solo Colonists when the Buff Clan attacked the excavation site and leveled New Lopia, killing many of the third wave of immigrants.
