Garmund was the third son of Lord Ormund Hightower and his first wife, who died in childbed at some point. He had two elder brothers, Lyonel and Martyn, and a sister, Bethany. During the Dance of the Dragons, his father married again to Samantha Tarly, known as Lady Sam, who would later marry his brother Lyonel.
Garmund served as a page and cupbearer to House Tyrell at Highgarden during the Dance of the Dragons. In 131 AC, Lord Lyonel accepted Lord Corlys Velaryon's peace terms for the end of the war, despite initially resisting them. According to Grand Maester Munkun's True Telling, this is because the Tyrells forbade him to raise a host or go to war without their leave, with the implicit threat that Garmund would pay for Lyonel's disobedience with his life, as every ward is also a hostage.
