There are differences between the Seat Witches.
Margaret is the youngest Seat Witch, with unparalleled talent. However, among the Seat Witches, she is not particularly strong, ranking at the bottom.
She is still young and has potential for improvement, but the Prophet and others have no expectations of her, believing she has gone astray; otherwise, she wouldn't have been discarded back then.
Years ago, during the Conqueror's expedition, the Prophet led a group of witches to escape the court and established the Witch Forest. Over the past hundred years, eight Seat Witches have emerged from the Witch Forest.
By the standards of the Conquest era, only Thunder and the Prophet could be regarded as Seat Witches, while the others were merely High Ranking Witches — The witches have been severely oppressed in recent years, leaving no trace of their old combat power, and the external environment is extremely harsh, so the past standards cannot be applied.
