Three Suns Empire

The Three Suns Empire emerged as a federation uniting British and Japanese empires. Shortly after its formation, the Japanese Yamada Corporation merged with the British Weston Corporation, cementing the TSE's role as the leading economic power.

Originally consisting of British, Japanese, India, Indonesia, and Australian governments, the people of TSE gave up or sold their territories to the United Nations, shifting their focus to prioritizing technological and space exploration development. During their expansion into space, they found many planets consisting of valuable resources, further increasing their status as the leading economic power in space.

The TSE's main military force are the Royal Crown Marines.
