Chie Research Base is a space station built from the damaged remains of a Blrakkrashiverinth Battleship. The location of the base was kept secret but it was somewhere in the small nebula south of the “Creepy Passage.” It was originally operated by the Star Army of Yamatai, but after the separation of the United Outer Colonies from the Yamatai Star Empire, the base was left under UOC control.
The exactly whereabouts of the base are currently unknown but they are once again inside Yamatai's territory.
Chie was assigned various units that were tasked with collecting salvage from Mishhuvuthyar battle sites and bringing it to Chie for study1).
Research from Chie Research Base, including a membrane-based water circulation system, was used in the designs of the Ayana-Class Escort, Amaterasu-Class Cruiser, and Nir-Class Colony Ship and became part of Motoyoshi Fleet Yards Life Support Systems.
