Before the cataclysm, Pierro was a royal mage of Khaenri'ah and lived with the Traveller's Sibling for a time. He failed to gain favour with Khaenri'ah's ruler, 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 among the pure-blooded Khaenri'ahns cursed with immortality, gazing upon Ronova as she implanted the curse upon him.
