A Jongleur
Jongleurs are people who have talents in either music, comedy, tumbling, or magic tricks.
They travel around the country performing for money at local taverns and inns. The presence of a jongleur ensures that a tavern will do better business, and the performer will also receive drinks, a meal, and a place to stay on the house. Will posed as a jongleur once while he was on a mission to Castle Macindaw to find the so-called Sorcerer. He also posed as a Jongleur in Hibernia, to get information in The Green Harper about The Outsiders. Will and Maddie posed as a traveling father and daughter jongleur duo for a secret mission in Gallica in The Missing Prince.
Jongleurs are welcomed with open arms everywhere they go, and they often make good money. In addition, a strange phenomena happens that, after an hour of performing for a group of people, a jongleur will be welcomed into their midst and talked to and in front of as if everyone had known him their entire lives. Being a jongleur is, presumably, a male profession.
