|Title||Lord of Riverrun|
|Book(s)||The World of Ice and Fire (mentioned)|
When the riverlands were invaded by Harwyn Hoare, King of the Iron Islands, Tommen's natural son, Ser Samwell Rivers, was slain at the Tumblestone. Lord Tommen abandoned Riverrun without a fight and fled with all his strength to join the host assembled at Raventree Hall under Lady Agnes Blackwood. Resistance, however, proved futile and the riverlands fell to King Harwyn.
