Asteroid and volatile-rich system in Sparks Cluster (IC 4756) - capital of The Grand Confluence, a multi-clade civilization.
The Grand Confluence
Multi-clade civilisation in the Sparks, a local stellar cluster (IC 4756), attracting other species to join into the "grand confluence". It is a large, somewhat expansionist asymptote civilisation.
The Grand Confluence apparently developed around a very early (pre-First Federation?) AI probe ("The Founder") from the Sol system, that for its own reasons set up a "waystation" to build various transapientech devices in orbit in the very asteroid and volatile-rich system now called Confluence (Lambda Scintilla). Later various clades arrived, likely intrigued by the emissions from the now long defunct transapientech factories. They traded, fought, combined and synthesized for a long time before developing into the current form, not unlike the development of Gerkletoss. Over time a stable religion/philosophy has developed, where all beings are invited to join the unique and all-encompassing stability and confluence the civilisation can offer.
