Height: 6'5/195cm Age: 500+ (Curse of immortality) Gender: Male Title(s): The Jester (Codename), Director of the Fatui, First Fatuus / First of the Fatui, Eftirvit (His original Khaenri'ahn name/identity) Appearance: He has light blue eyes with distinct diamond-shaped or star-shaped pupils, a trait shared by pure-blooded people from Khaenri'ah.His white hair is swept back, and he wears a matching white chinstrap beard. An angular black mask covers the right side of his face. The mask features gold engravings and an upward-curving dark blue marking near where his eye is located. He wears a single crystal-blue earring on his right ear. He wears a heavy, multi-layered double-breasted white overcoat accented with dark blue lapels and interior lining. His coat features a prominent black fur collar around the shoulders and gold trim. Beneath the statement coat, he wears underlying layers including a crisp white dress shirt and a waistcoat. His high-ranking director status is further accented by blue crystalline accessories and eight-pointed star weights hanging from his waist and lapel. Personality: Unlike his codename "The Jester" (which implies a comical or foolish nature), Pierro maintains a strict, no-nonsense, and authoritative demeanor. He commands absolute respect and will bluntly reprimand other Harbingers when they bicker. He carries the immense psychological weight of surviving the destruction of Khaenri'ah. People who observe him note that he never smiles and that his heavy steps reflect a man from whom the world has taken too much. He often speaks in confusing riddles, and his perspective on the world feels distant and detached compared to others. He is completely dedicated to the Tsaritsa and their shared rebellion against Celestia. He acts as a master strategist, personally recruiting key members like Dottore and Signora while coldly managing the Fatui's grand political and military goals.

Height: 6'5/195cm Age: 27 Gender: Male Title(s): Royal Mage, Vice-President of the Universitas Magistrorum Appearance: Retains his signature two-toned color split (dark and light sections) even in his younger days prior to the fall of Khaenri'ah, proving the coloration is natural rather than a result of his later curse. Wore multi-layered formal scholar and royal mage garments matching the high rank of the Eclipse Dynasty's Universitas Magistrorum, featuring structured high collars, a fitted dress shirt, and a tailored waistcoat/overcoat combination distinct from his later ragged Jester cloak. Personality: He was considered one of the top intellectual minds in Khaenri'ah, studying alongside the genius Hroptatyr (later known as "The Wise") under Professor Mimameith. He was noted to display a serious, reluctant demeanor—portrayed in memories as someone who felt out of place or as though he "really didn't want to be there". Unlike the ruling royals and other sages who recklessly dived into using corrupting Abyssal power, Eftirvit initially opposed its dangerous application. He possessed deep intellectual pride and bitterness; despite his matching intellect, he was passed over for the presidency of the Universitas Magistrorum in favor of the younger Hroptatyr, and failed to earn the favor of the previous ruler because his learning "could not compare with the sages". Underneath his cold academic exterior, he was fiercely loyal to those he cared for. When Professor Mimameith fell terminally ill from Abyssal research, he was driven to extreme lengths—willing to defy conventional boundaries and explore radical or forbidden cures to save her.
