The Greater APAC Co-prosperity Sphere, also known as GACS, Pan-Asian Treaty Organization, or the Sphere, is the supranational political-economic alliance & the dominant power in APAC space. Covering a space sovereign of over classified parsecs, with over classified googolplex sentients, it includes the majority of great powers across APAC, with colonial interests scattering entire known cosmos & beyond. The alliance traced their roots to a mutual treaty between the Yamatoran, the NKR & many outer worlds of the Confederates during their war against the Borg. The GACS, along with PEE and GCSS, would be the single pan-multiverse largest economy, had it been one sovereign nation, based on GDP alone.
