20 years prior to the events of Octopath Traveler, Josef performed the Kindling ceremony, in which a priest of the Sacred Flame takes Aelfric's Lanthorn and lights the Sacred Flame in Saintsbridge, Goldshore, and Flamesgrace.
5 years later, he adopted Ophilia, who had been orphaned as the result of a war, and introduced her to his daughter, Lianna. He taught the girls to treasure the gift of life.
During current events, at the onset of Lianna's Kindling ceremony, he falls ill due to being discreetly poisoned by Mattias. He understands and accepts Ophilia's willingness to perform the pilgrimage in her sister's place. He succumbs to the poison around the time Ophilia reaches Goldshore.
