Song of Ice and Fire
House Redwyne of The Arbor
Although the Lords of Redwyne have been sworn to Highgarden for over a thousand years, in more recent times these traditional enemies of House Vara have often found common cause with them. Both supported the Targaryens in the War of the Usurper (Known as Robert’s Rebellion in the north) and neither had much use for most of the Blackfyre pretenders.
The Arbor maintains the greatest fleet in Westeros and this has landlocked the armies of Oroca when their states were at war with each other. However, the Redwyne’s have never been able to rout the Mardoxian armies from their mountains, even after sacking Oroca Hall.
