The unfortunates in 2015’s The Fifth Season live on a world almost as active as Jupiter’s moon Io, a world constantly rattled by tremours and reshaped by volcanoes, a world where geological and historical timescales are the same.
Embracing whimsical gallows humour, they call their single landmass “The Stillness”.
Any particular community on this world can be certain that, in time, it will be wiped out by earthquake, tsunami, acid rain, or abrupt climate change. Humanity as a whole survives on the Stillness because until now, no calamity massive enough to kill absolutely every human has happened.
Thanks to the forward-thinking social policies of the Sanze Empire, humanity’s run of luck is about to end.
