A short, severe eulogy for the planet, told in three movements separated by intervals too large for language. The first day belongs to an artificial mind, the last thing on Earth that knows it is on Earth, narrowing through its final hours of compute. The second belongs to a single archaeon four kilometres down, the last living cell in a planet long sterile. The third belongs to matter itself, dispersing into the dance and cooling of the cosmos, where the music continues and is, in the same motion, ending. A book about endings at three scales, written to be read in one sitting.
