The Planet was settled by Colonist of Oyata, once their world became almost uninhabitable. The large amount of inhabitants of the Planet had to be evacuated to this planet who was a reconstruction of the old Oyata, who had been incredibly polluted and destroyed during some of the Conflicts of the Empire. Some early settlers had already colonised other worlds, and many people from Oyatan origin left those worlds to come to Eyen due to it being a place to preserve Oyata culture. Its Fauna was also transported to the Planet, most notably the old Vilin Flower, who adapted well to Eyen's ecosystem.
The Colonization of Eyen was sponsored by the Weng Family after Imperial approval.
Eyen was the main center of a large battle between the forces of the Empire of Mankind and the Alliance of Five, who had been bombarding the Planet during several months causing millions of deaths.
