Mudge was a swineherd in service to House Osgrey during the reign of King Aerys I Targaryen.
By 211 AC, Mudge was an old man and was stoop-backed. He was a follower of the Faith of the Seven.
Mudge once traveled to Oldtown. He led the devotions every seventh day for those sworn to House Osgrey. However, twice a year, a real septon came through to forgive people's sins.
