The Autumn Uprising, led by Lord Kedar Pandey, was a rebellion in the Summerlands from 12 to 13 SM. It resulted in the extinction of House Summers, which had ruled the Summerlands since the eighth century of the Empyrean Ascendancy Era. 

In 481 SM, Lord Morvan Osmont had his men assassinate the members of House Thoren and installed House Ashmire as the new Lord Protector of the Summerlands.
