The Christmas Flood

The Christmas Flood was a disastrous event that took place on Christmas Day, 2082, in Appalachia. David Thorpe, the leader of the Cutthroats, destroyed Summersville Dam to attack the Responders, who had captured his lover Rosalynn Jeffries. It devastated the city of Charleston and caused the death of over 1000 Appalachian survivors, including Jeffries.
