Ser Arthur Arryn is a knight from Gulltown in the Vale. He is currently in service with Septon Joseth, a travelling holy man currently on a tour of the eastern Riverlands.
Arthur, accompanied by Septon Joseth, visits and stays in the village of Redwater Watch for three days where they deliver sermons and perform a small amount of public service for the locals. Following their stay, they arrive in the nearby larger (and dirtier) Dale's Town whose general filthiness, both physical and spiritual, upsets both men though they agree to remain there for the night before moving on. While booking themselves a room in the Maidenvault, a former brother converted into an inn, Arthur makes the acquaintance of another travelling knight - Ser Gwayne, hailing from the small town of Llyn in the northern Reach.
