Temperatures plunge far below freezing for several days. Despite the valiant efforts of your slaves and overseers, your crops do not survive.
The angry Gods plunge your land into complete darkness for 27 days. When you finally see the sun again, your fields are covered with yellow, rotting, lifeless plants.
Rain pours from the sky day and night for nearly a month. Your fields have become lakes. Your crops are destroyed.
The temperature soars, and the sun stares down out of a cloudless sky for 3 solid weeks. Nothing remains of your crops but dried husks.
Ranks upon ranks of marching Soldier Ants cut a swath through the land and destroy your fields.
Suddenly, a shadow passes over the land. . . An immense swarming cloud of hungry locusts descends upon your fields and devours your crop.
