The Elysian Naval Arsenal is a massive Elysian Celestial Navy facility that serves as a storage, maintenance, and production facility for military equipment. It was built on Keren III in late YE 34 by the Star Army of Yamatai to increase Elysia's defensive capacity.
Ground facilities are built in a traditional style reminiscent of great cathedrals and columned temples, made with free-standing giant stone bricks that will stand the test of time, and decorated with stained glass windows and elaborate carvings. Statues of great Elysian warriors stand on columns overlooking fountains and reflecting pools, watching over the great parade fields and plazas. Although built by the Star Army, it couldn't be more clear that it was built with Elysian design input and with great appreciation for Elysians.
Underground, the Naval Arsenal is equipped with armored bunkers designed to resist attack by starship weapons, connected by a vast network of utility tunnels and underground storage areas. It is quite a fortress.
