Hailing from the Northern Country among the oldest summoned wizards, White persists as a ghost after his twin brother Snow slew him during a three-day confrontation—a clash culminating in Snow’s self-defense. Snow bound White’s spirit to the living world, tethering their souls and trapping White between realms. This entanglement fuels White’s existential doubt: is he his own lingering ghost or an illusion woven from Snow’s memories and desires?

Snow and White share a bond forged in isolation, recalling no parents or guardians. They deem their relationship self-sufficient, embodying every role—mother, father, sibling, friend, lover, hero, and villain. Once nomadic stained glass artists, they founded and abandoned northern villages under their guardianship. Their equilibrium shattered when philosopher Murr questioned Snow’s solitude, igniting Snow’s wish for separation. White unraveled into frenzied rage, desperate begging, and manic flattery before collapsing into depression, threatening mutual annihilation. The conflict ended with White’s death. Though both deny blaming Murr, they hurl consistent vitriol toward him, betraying deep-seated resentment.

White manifests two physical forms. His child guise reflects his true self—magical power peaked in youth—with neatly trimmed black hair (slightly longer than Snow’s), golden eyes, a white buttoned shirt, and a poncho-like cape. As an adult, his hair parts leftward; he dons a suit with a small cape. His wizard crest, half of a shared emblem with Snow, marks his neck’s left side. He adopts adulthood for activities like drinking bitter alcohol, which he endures solely for amusement or Snow’s companionship.

Playful and mischievous yet underpinned by wisdom, White often restrains Snow’s fury over perceived slights from younger wizards, coolly noting words cannot cause true harm—a restraint perhaps born of ghosthood rather than nature. Alongside Snow, he exudes parental condescension and warmth toward younger wizards, relishing their growth while earning renown as a shrewd listener and problem-solver. Beneath this lies Northern wizard cruelty: indifference to tragedy, readiness for brutality, and millennia-hardened cynicism that dismisses undeserved pleas.

White and Snow jointly raised wizards Oz and Figaro. Their overwhelming magic enforces dominance over younger Northern wizards within a power-centric culture. The twins frequently speak in unison, their thoughts and wills near-perfectly aligned. White’s magical tool is a doll named Father, paired with Snow’s Mother doll—a testament to their shared history crafting and playing with dolls.

Trivia notes suggest White draws inspiration from "Snow White," his designated major arcana card being "XXII: The Fool." Paintings in their residence may depict both twins before White’s death.
