Friard d'Indret was a 6th-century religious figure known for his missionary work in the Nantes region. Born into a family of laborers in Besné, he eventually sought a life of asceticism. After spending time in solitude on the Loire island of Vindomitte, he joined a companion named Secondel. Together, they lived lives defined by prayer and penance, eventually settling in the Brière marshes to reside in separate cells.
