House Redwyne of the Arbor holds the lush island at the southwest tip of the Reach, where the soil is rich, the sun is generous, and the grapes the smallfolk tread each autumn become the most famous wines in the known world. Arbor gold and Arbor red are poured at the tables of King's Landing and at the courts of Pentos and Volantis alike, and a great share of the wealth of the Reach passes through Redwyne hands.
The Redwynes also field the largest fleet in the realm, hundreds of war galleys strong, with which they keep the ironborn from their shores. Lord Paxter Redwyne is wed to Mina Tyrell, sister of Mace, and his twin sons Horas and Hobber, known the realm over as Horror and Slobber, are second cousins to the heirs of Highgarden.
