The Ten Black Days of Eleint

Revolution

Commoners rise up and slaughter many Tethyrian nobles, including the royal family, ending the Lion's Dynasty and beginning the Tethyrian Interregnum, where Tethyr has no clear ruler

Commoners rise up and slaughter many Tethyrian nobles, including the royal family.  Of the 56 landed nobles, and over 100 lesser, titled nobles, only two dukes, a count, and five barons survived the Black Days. Over 550 family members had been murdered and over 1700 commoners had been killed by mercenary guards or out-of-control fires.  The Lions' Dynasty, which had ruled Tethyr since 959 DR was utterly destroyed, leaving no clear ruler and beginning a dark period of war and calamity known as the Tethyrian Interregnum.
