The war, led by Lyanna's fiancé Robert, her brother Eddard, and their foster father Jon Arryn, lasted "close to a year".[36] Lyanna's exact whereabouts during this time are unknown. Rhaegar himself could not be found, either, for a large part of the war,[22] though he finally returned "from the south"[37] after King Aerys II had dispatched Ser Gerold Hightower, Lord Commander of the Kingsguard, to find him.[22] Robert and Eddard faced Prince Rhaegar and the royal army at the Trident, where Robert slew Rhaegar in single combat and the rebels defeated the royal army.[3] A fortnight later, the Sack of King's Landing officially ended the war,[38] though Lyanna still remained missing and the last opposition still had to be dealt with. From King's Landing, Eddard Stark rode south to the Stormlands to lift the siege of Storm's End. From there he rode to the a place Rhaegar was said to have named the Tower of Joy, located in the Red Mountains of Dorne.
