《Ophiuchus Historia》
.
At the turn of a dying century, humanity turns towards life amongst the stars as the universal solution to all its problems. Massive space stations envisioned in each of the five Earth-Moon Lagrange points formed a region around the blue planet that would come to be known as the 'Earth Sphere'. However, the peace they bought would prove to be short-lived as conflicts once again break out amongst major players on the world stage for resources and territorial rights on the newly completed space colonies.
A massive exodus began, abandoning the Earth to its own folly, and lasted nearly thirty years until territorial lines are redrawn and the various warring factions lose interest. Three years after this uneasy truce, world leaders were finally convinced to come together and negotiate an alliance to open a new chapter in humankind's history.
A hundred and thirty-three years after the successful launch of the first colony satellite, a new year designation was retroactively applied to commemorate the first step towards universal harmony: A.C., After Colony.
消逝的世纪末，人类转向迁居宇宙以解决地球上的种种问题。 设在地球与月亮两天体之间的五个天平点上的庞大太空站环绕着地球，与地球形成了后来所谓的'地球圈'。 可惜，这番功夫所换来的和平并不持久。 地球各个主要权势为了互相竞争资源及新开发的殖民领地，再次发生斗争。
逃离战火的人们纷纷舍弃地球，移民宇宙殖民地，直到约三十年后，共争的各方重新划下领域界线，失去战意收场。 之后又经三年，才说服世界领导人聚首结盟，终于展开了历史新章。
距离首座殖民卫星发射一百三十三年，人类为纪念向世界和平迈出第一步，倒冠新年号 '殖民后'，统称：A.C., After Colony。
