Imagine an interstellar setting that incorporates the most cutting-edge ideas in nanotech, space exploration, germline engineering, artificial intelligence, and transhumanism, to create a hard science "future history" set over thousands of years, as terragen life expands throughout the galaxy at close to the speed of light

Imagine a vast civilization ruled over by god-like Archailects, linked by artificial wormholes, destabilised by ascensions and transcensions as nanotech civilizations and superturing entities break through singularity barriers, while clarketech devices from the hypersingularitan powers are found on abandoned planets or drifting in space, mystifying archaeologists and scientists alike...

A civilization peopled by a diversity of sophont beings that is mindboggling - gengineered humans, biochip and nanotech enhanced cyborgs, human-animal splices and rianths, lazurogened prehistoric life, nanocivilizations, pro- and anti-human ai, sentient ships and buildings, virtual universes, robot empires...

Imagine countless colonised and terraformed worlds, biospheres, orbital habitats, space stations, ships, fleets, alliances, mysterious aliens, factions, intrigues, memetic subversion, and more, much more.
