Tier was famous for its tightly interconnected multi-species society, a society which the habitat had been specifically designed to support.
Description[edit | edit source]
Tier was composed of nine levels arranged as a stepped cone revolving around a central axis. All of its levels revolved at the same speed, creating higher apparent gravity on the outer levels and lower apparent gravity on the inner levels. Levels were divided into compartments up to hundreds of kilometres long filled with atmospheres of different types and held at different temperatures. The habitat's hollow core was fitted with a complex array of mirrors and mirror fields providing precisely timed, attenuated and modulated light into the compartments. The design of Tier allows the various compartments to mimic the conditions on a hundered different worlds for a hundered different intelligent species. 
Levels Three and Four featured one standard gravity.
There were many facilities available in the c. 19th century CE. The View Hotel was located on Level Three, and the Night City was on Level Four. The Ysner-mistretl racetrack was one level up from the level containing the embassy of the Homomdan Empire. Elsewhere was an excellent Affront hunting reserve section.
History[edit | edit source]
The habitat did not send ships to investigate the Esperi Excession during the crisis in the c. 19th century CE.; Culture and Affronter craft were requested to leave Tier during the associated and short-lived Affront-Culture War.
Society[edit | edit source]
The Tier Sintricates distrusted any entities that had less of a biological basis than themselves. The movements and communications of drones and machine intelligences were closely monitored. The avatars of Minds were met with outright hostility beyond the outer docks, where they were extended every hospitality. The discrimination was gladly tolerated given Tier's other superlative social attributes.

Culture[edit | edit source]
Ysner-mistretl races were held on Tier for millennia by the 19th century CE. The race track resembled a two-kilometre wide circular amphitheatre, with each level of seats rotating at different speeds.
