The gatekeeper of the (unnamed) Roman wall is Julian, the fifth member of his family to hold the job. In Hal Foster's comic strip, Valiant and Gawain also journeyed to a wall which was built during the days of the Roman Empire - specifically the famous Hadrian's Wall - and encountered the third-generation guard Julian, who also assisted Valiant in his investigating the source behind unclear reports of danger to Camelot.
