SSTO

The Southern Stability and Trade Organization (SSTO) was established to promote regional stability and trade, initially founded by the Meridian Republic and United Aequor Federation. Forty years ago, Meridian extended an invitation to the Aurorian Republic, but due to strained relations between Aequor and Aurorian, Aequor only agreed to allow Aurorian's inclusion if Meridian also invited Heliosia. This marked the beginning of SSTO's expansion, which occurred just before the outbreak of the Heliosia civil war.
