Alluvion
Alluvion is the holy city and home of the god of technology Triune and the ever-expanding epicentre of intelligent activity in the Drift.1
Geography
Alluvion has a roughly ovoid shape and rests atop a relatively flat asteroid. An accretion disc composed of chunks of other planes claimed by the Drift spirals slowly into the city, gradually adding to its mass. A massive, unfathomably black gravity well beneath Alluvion draws in this stream of planar detritus; Triune’s faithful believe the god has harnessed a black hole. The gravity in the city itself is comparable to that of Absalom Station, and a carefully filtered atmosphere supports most oxygen-breathing life.1
Alluvion travels throughout the Drift whenever Triune wills it or at least according to no predictable timetable. Those who have experienced such relocation while in Alluvion compare it to entering or exiting the Drift. Only those summoned by Triune to the city can reliably find their way there.1
Government
Alluvion is ruled by Triune and its high priests, who concern themselves primarily with collecting, organising and interpreting information.1
Inhabitants
The majority of Alluvion's population are androids, and the city has a significant verthani minority with a fanatical embrace of cybernetic augmentation. Thousands of modular anacite servitors called animotes crawl incessantly through Alluvion, harvesting portions of other planes from the accretion disc and incorporating them into the ever-growing city, extending its infrastructure and repairing damage. In addition to its indeterminate and changeable location, the city is defended by the technomancers who make up the priesthood as well as the animotes, which can join together to form building-sized enforcers.1
Culture
Alluvion serves as a microcosm of the Drift, incorporating portions of the multiverse's planes and functioning as a proving ground for advanced technology. Technological advancement rules every aspect of the communities here, including developing technology to a point where it mimics biological life. Alluvion has a number of public and private facilities devoted to virtually every facet of technological research. In addition, the city boasts a surprising diversity of cuisine that results from modified plants and animals as well as widespread interest in molecular gastronomy.1
Some of Alluvion's faithful continue to worship one of Triune's constituent gods, with androids devoted to Casandalee, anacites to Epoch, and a few ysoki to Brigh.1
Resources
Alluvion's greatest resources by far are the vast repositories of information and innovations. Interconnected research facilities full of cutting-edge equipment allow multidisciplinary collaboration and research. Researchers perform endless experiments with universal polymer bases, which are in nearly unlimited supply here (though carefully apportioned by institute heads), and the multifunction units themselves are constantly being experimented on. Rumours abound of quantum-state UPBs, which can serve several functions simultaneously, and biological UPBs that may eliminate the blurry line between biology and technology at the molecular level. Other minor industries revolve around the rare minerals sometimes drawn into the accretion disc.1
Alluvion's power supply is seemingly limitless and never falters despite the constant and significant draw.1
