Prince Gawen Gardener was a member of House Gardener of Highgarden and the second son of Mern IX Gardener, King of the Reach.
When his father, King Mern IX, made an alliance with Loren I Lannister, King of the Rock, to join their armies against Aegon the Conqueror, Gawen rode beside him carrying the Gardener banner. Gawen burned in the Field of Fire alongside his father, brothers, and his father's grandsons when Aegon and his sisters, Visenya and Rhaenys, unleashed the fury of their dragons.
