Mern IX Gardener

Mern Gardener, also known as Mern IX, was the last of the Gardener Kings of the Reach. When Aegon the Conqueror invaded Westeros, King Mern joined forces with Loren Lannister, the King of the Rock, to face Aegon in battle.

However, Aegon unleashed his three dragons, Vhagar, Meraxes and Balerion the Black Dread against the combined might of the Kingdoms of the Reach and the Rock. Four thousand men perished, consumed by the dragons' fire, earning the site of the battle the name of 'the Field of Fire.' Among the dead was King Mern himself. With Mern's death, the Gardener dynasty became extinct.
