Acid Season: 2322–2329 Imperial. Proximate cause: plus-ten-level shake. Location: unknown; far ocean. A sudden plate shift birthed a chain of volcanoes in the path of a major jet stream. This jet stream became acidified, flowing toward the western coast and eventually around most of the Stillness. Most coastal comms perished in the initial tsunami; the rest failed or were forced to relocate when their fleets and port facilities corroded and the fishing dried up. Atmospheric occlusion by clouds lasted seven years; coastal pH levels remained untenable for many years more.
