Utopia Sphere dyson swarm, consists of billions of habitats and biospheres, populated by sophont and subsophont/subsapient beings. A similar nearby dyson is called Wallace.
The larger number of biospheres are inhabited by subsophont animal and plant life, which are provided with optimal conditions and a stable ecology. Many other habitats are home to presapient life and freed partial provolves, some of which have established tribal communities. A somewhat smaller number have prims and low tech sapients of all clades and categories, from hu to splice and neogen (but rarely more than one species per habitat). The habitats are very popular with biologists, sophontologists, and ethnologists. The system is linked by a medium gauge wormhole for visitors, and there are also several godweb archailect-only links for the Utopia Sphere minds and their seraiph.
