Margaery Hightower

Margaery of (446 AC - 466 AC) House Hightower was the daughter of the King in the Hightower, Reginald Hightower. During Loren's War, Margaery and her twin sister Elena were captured by Loren Lannister. Loren hoped to use the two hostages as leverage to convince Loren to give up Brightwater Keep and its surrounding lands, but Reginald refused. The armies of Hightower and Lannister clashed outside of Brightwater, and Loren was defeated. As his army returned to their ships, Loren returned Reginald's daughters to him...by catapult. The death of Margaery and Elena was heavily felt by Reginald, who swore vengeance. Their deaths are the motivation behind Reginald's attack on House Lannister at the end of The Red Spring and the start Iron War.
