Famine

A great depression & dust bowl type situation
begins in a place that's important to you. 1/3
of the people lose jobs, poverty is rampant, food
is scarce, and people are starving. This causes
mass chaos in this area within 2d4+1 days.
"The law only gives crooks more time to cover
up the books. Trust Big Balls & the Dogefather."
