The phrase 'once cast off wife now untouchable queen' instantly makes me think of Cersei Lannister from 'Game of Thrones'. Her journey is a rollercoaster of power plays and personal vendettas. Initially, she was married off to Robert Baratheon, a union that was more political than romantic, and she endured his infidelity and indifference. But after his death, she clawed her way to the Iron Throne through sheer cunning and ruthlessness. By the later seasons, she’s this untouchable figure, burning her enemies with wildfire and ruling with a cold, unshakable grip. What fascinates me is how her character flips the script—from being sidelined to becoming the most feared woman in Westeros.
Another angle is Daenerys Targaryen, though her arc is more about rising from exile than being cast off. But if we stretch it, her brother Viserys treated her as a pawn, selling her to Khal Drogo. From that low point, she builds an empire, only to become 'untouchable' in a tragic, fiery way. Both women embody the trope of underestimated figures who ascend to terrifying power, but Cersei’s story feels more like a calculated revenge fantasy.
