EX-1 Keren

When the central government attempted to colonize this system in YE 30, they were surprised to discover that there were already 144,000 Elysians living on Keren. These Elysians had secretly moved to Keren during the Elysian exodus from Yamatai to Veritas around and before YE 16.

Flag of Keren

In YE 34, the Star Army of Yamatai built the Elysian Naval Arsenal on Keren III.

The Yamatai Star Empire placed a global communications network of Emrys Satellites into orbit in YE 36. Civilian cargo shipping is primarily provided by Trinary Star Shipping, which has storefronts in all of the planet's major cities.
