Manaria Sousse is the crown princess of the kingdom of Sousse and a distant relative of Claire. She's best known as the world's first confirmed quad-caster—someone with the rare ability to master all four elements at the highest level.
She was Claire's first love, though Claire initially mistook her for a boy. After helping Claire work through the trauma of losing her mother, the two grew genuinely close and maintained a correspondence for years afterward.
Manaria's time as crown princess ended when she was exiled from her kingdom. The exposure came down to her visits to brothels and, more specifically, an affair she had with one of her maids—a scandal significant enough to cost her her position.
