This High Septon was appointed High Septon at the age of eight, making him the youngest High Septon in the history of Westeros.
His appointment was made by King Baelor I Targaryen who informed the Most Devout that the Seven had revealed the new High Septon's identity to him after the sudden death of his predecessor. The boy was said to be a street urchin or the son of a draper, but Baelor claimed he saw the boy perform miracles, that the boy spoke to doves and they answered him back in the voice of the gods. Despite their misgivings the Most Devout agreed to the King's request since Baelor did so much for the Faith of the Seven. Though Baelor claimed the boy could work miracles, he failed to save the King's life when he fasted himself to death.
