Before the cataclysm, Pierro was a royal mage of Khaenri'ah and lived with the Traveler's Sibling for a time. He failed to gain favor with Khaenri'ah's ruler, likely King Irmin, due to being less capable than the country's sages and could not stop them from doing something that tore away the "veil of sin." This brought "divine wrath and destruction" to the nation, and Pierro was presumably among the pure-blooded Khaenri'ahns cursed with immortality.
