|Title||Lord of Stone Hedge|
|Book(s)||The World of Ice and Fire (mentioned)|
Harwyn Hoare, King of the Iron Islands, invaded the northern riverlands when they were under the rule of the Storm King Arrec Durrandon. Lothar's neighbour, Lady Agnes Blackwood, led the rivermen in resisting Harwyn's ironborn, but Lord Lothar attacked her army from behind. Some have theorized that Lothar hoped to become King of the Trident once Harwyn defeated Arrec. However, Harwyn claimed the riverlands for House Hoare. Six months later Lothar rebelled against this new King of the Isles and the Rivers, but Harwyn crushed the rebellion, sacking Stone Hedge and starving Lothar in a crow cage.
