The Third Year of the Longwinter: Spring Equinox
The ice spilled off the growing continental caps, and gathered in sheets over the open sea. From the mountains too the ice descended, the glaciers flowing down valleys gouged out by their predecessors millennia before. When they reached the lowland the glaciers spread out and flowed together, merging into sheets of ice that covered the ground, covering the traces of forests, farms, cities.
Across swathes of the northern continents, there were few people left to mark the latest equinox.
