The fourth-and-only-surviving planet of the Alpha Centauri triple-star system — homeworld of a civilization that has died and rebuilt itself two hundred times under three unpredictable suns.
Trisolaris is the experience of three-body chaos lived as planetary fact. Its inhabitants evolved the ability to dehydrate themselves into sheets that can be stored and rehydrated when conditions return to habitable — a single long survival strategy made flesh. Two hundred civilizations have risen on its soil and two hundred have died, frozen, burned or pulled apart by tides. The current civilization, Number 200, has finally reached a level of technology that lets it abandon the planet entirely. In this book Trisolaris is known to the reader mostly through the game and through a few transmissions decoded by the ETO. It is not yet visible. It is coming.
From orbit, a small terrestrial world with a single oversized moon, illuminated unpredictably by one, two or three suns at any given time. Surface conditions vary from frozen-air dark to surface-melting glare in a single day. What civilizations have endured: scaffolded glass cities, vast sun-mirrored plazas, and (in Civilization 200) the unfolded sophons hanging in the sky like geometric cathedrals.
