The Obelisk Gate (The Broken Earth, #2)

by N.K. Jemisin

Season of Yellow Seas: Approximately 9200 Before Imperial. Proximate cause: unknown. Location: Eastern and Western Coastals, and coastal regions as far south as the Antarctics. This Season is only known through written accounts found in Equatorial ruins. For unknown reasons, a widespread bacterial bloom toxified nearly all sea life and caused coastal famines for several decades. Twin Season: Approximately 9800 Before Imperial. Proximate cause: volcanic eruption. Location: Somidlats. Per songs and oral histories dating from the time, the eruption of one volcanic vent caused a three-year occlusion. As this began to clear, it was followed by a second eruption of a different vent, which extended the occlusion by thirty more years.
