Lizbeth Sargant, head of House Sargant and the second season’s central antagonist, clawed her way to power through ruthless ambition, compelled by aristocratic demands to produce an heir. She wed a highborn noble, bore a son named Adam, and coldly disposed of her husband once his purpose was served. Adam initially thrived under her control but ultimately defied her, eloping with Iris, a human slave. Lizbeth hunted the pair years later, precipitating Iris’s murder and Adam’s self-destruction, then seized their daughter Philomela and her mechanical guardian, Alcyone, dragging them to House Sargant’s gilded prison.

Philomela endured years of brutalization under Lizbeth’s tyranny—beaten, berated, and locked in darkness for perceived inadequacies. Lizbeth reprogrammed Alcyone to strip the child of solace, weaponizing isolation. Her machinations birthed the Webster Tragedy: werewolves, manipulated into slaughtering the Webster clan, stole their arcane spiders for House Rickenbacker. Philomela, forced to watch the carnage, bore scars of terror and guilt.

Years later, Lizbeth coerced Philomela into wielding the Testament of Carnamagos, a forbidden grimoire, to siphon magic from academy students. Feigning promises to resurrect Philomela’s parents, she plotted to sacrifice the girl to resurrect Adam. During the ritual, confronted by Chise and allies, Lizbeth merged with the grimoire’s essence, summoning a primordial entity. Adam’s curse—embedded in Alcyone’s core—erupted as a vengeful shadow, assaulting Lizbeth. Though she taunted Philomela with psychological torment, the girl, fortified by allies, repelled the entity using ancient runes.

Lizbeth’s reign ended when a Webster Tragedy survivor—a werewolf cub she’d enslaved—severed her head to silence her secrets. She died defiant, offering Philomela and Lucy Webster no absolution, her motives entombed with her.

A portrait of calcified malice, Lizbeth weaponized kinship and legacy, reducing lives to instruments for her dominion. Her arc epitomized the rot within magical aristocracy—a cycle of exploitation where power devours compassion, and heirs inherit only ruin.
