The Kounzu Faashi system consists of an orange dwarf star and a white dwarf in a relatively close orbit; nevertheless this small system contains a relatively large planet, the gas giant Saiygdja. This world is locked in mean-motion resonance with the white dwarf star Conwisa, the former completing five retrograde orbits in the time it takes for the latter to make two orbits, permitting it to survive the perturbation of the companion.

This system was first reached in 2096 AT by the autonomous exploration craft Vayu, and was first colonised during the Age of Expansion. Apart from the massive gas giant, this system had few easlily available resources, so the population was relatively small in number at first. During the formation of the white dwarf this system had been subject to very strong outgassing from the dying star, and this affected the composition of the atmosphere of Saiygdja. Using atmospheric extraction technology, the inhabitants of this system were able to construct an array of rotating space habitats.

The Uncontents

One unusual culture that emerged in this system during the Consolidation Era was the Cult of Uncontentment, a dystheistic and cynical movement that may have been influenced by the sparse nature of the local system. The Uncontents believed that the Known Universe was a failed experiment by an unknown entity or group of entities, and that these entities were either no longer interested in the fate of the universe, or that they no longer had the capability to affect events inside their creation. In particular many Uncontents believed that the period of cosmic Inflation had accidentally or deliberately continued for too long, making the Known Universe relatively empty and doomed to an even emptier future.

Some Uncontents believed that there may be better universes elsewhere in the multiverse, and that it may be possible to find such locations and migrate to them. Other Uncontents anticipated that eventually the Terragen civilisation might gain the capacity to create new and better universes of their own. A number of Uncontents have subsequently become involved in research into such possibilities, and a few have passed up the toposophic ladder into transapienthood, and (in the Current Era) some are believed to be involved in the creation and design of baby universes.
