High Steward of Highgarden

"The Andals swept across Westeros, destroying many ancient families and kingdoms. When the invaders arrived at the Reach led by Ser Alester Tyrell, House Gardener chose accommodation over battle, hoping honors and marriages would sate foreigners' ambition. The Tyrells were welcomed into service as hereditary stewards of Highgarden. Thousands of years later, they repaid the Gardeners for their acceptance."

- Randyll Tarly
