The Arbor is a large island off the southwest coast of the continent of Westeros, famous for its wines and the massive Redwyne fleet, roughly equal in size to the royal fleet. Lord Paxter Redwyne is the head of the house, and is brother-in-law and friend to Lord Mace Tyrell. By his wife Mina of house Tyrell, he has had three children: the twin sons, Ser Horas and Ser Hobber (mocked as Horror and Slobber), and a daughter, Desmera. Lady Mina’s mother is also a Redwyne, the notorious Queen of Thorns, Lady Olenna.
In the past, Ser Ryam Redwyne was one of the greatestt knights in history and served as Lord Commander of the Kingsguard. He was also Hand to a king, but he was a failure in that office.
