- Wallace Dyson - Text by M. Alan Kazlev
Utopia Sphere dyson swarm, containing billions of vast habitats populated by sophont and subsophont/subsapient beings. A similar nearby dyson is called Wilson. However, a larger number of habitats in Wallace are home to subsophont life. The ecologies and local environments of each habitat are carefully maintained at optimal conditions by utility fog and low grade / partial angelnetting. The habitats are very popular with biologists, animal psychologists, 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 seraiphim.

In 6222 a Nimbus colony was set up on Xi Bootis B I, but it persisted only for 400 years before dissipating. The inhabitants are mainly mixed baseline, tweak and cyborgs, ruled by the famous Xil AI. The Etaoin Roltz remain, having become a holy order guarding the sacred sites and ecology of the planet.
