Lambert sends Hubert to the Ardennes to live amongst the people and creatures of the forest. He studies to become a priest, and is soon ordained. Following Lamberts's assassination, Hubert becomes Bishop of Maastricht, then of Liége. Throughout his life he remains known as the apostle of the Ardennes, venturing much into the forest, gaining the trust (and the faith) of its people through the outdoorsman skills acquired during his hunting life. Hubertus becomes a reference and a sought voice whenever matters of the forest are on the table.
