Arthur Redwyne was the firstborn child of Alebar Redwyne and Princess Rhaenys Targaryen, who was King Aemon VI daughter. Alebar was the grandson of Lord Paxter Redwyne and the son of the heir to the Arbor, Horas Redwyne. He was born in the 334th year after Aegon I Targaryen’s conquest of Westeros, and after a labor that lasted several hours. His hair was light and lacked colour as a babe, though it would eventually turn red, though his eyes were the purple eyes that his mother had.
