Boiling Season: 1842–1845 Imperial. Proximate cause: hot spot eruption beneath a great lake. Location: Somidlats, Lake Tekkaris quartent. The eruption launched millions of gallons of steam and particulates into the air, which triggered acidic rain and atmospheric occlusion over the southern half of the continent for three years. The northern half suffered no negative impacts, however, so archeomests dispute whether this qualifies as a “true” Season.
