Retired Battle Monk
Tall and strong, aging but fit. His shaved head is tanned, leathery, and has stubble revealing male pattern baldness. He rarely wears anything but sleeveless saffron Buddhist monk robes.
Though mostly retired from the Ascension war and modern society, Art does spend an evening every month or so with the Old Guys watching major historical sporting events as they occurred in alternate timelines.
It is common knowledge that Art fought the hot part of the Ascension War for several decades before retiring to the monastery. Beyond that, few details are available.
