Amarantha

Amarantha is a High Fae, former general of Hybern who proclaimed herself as the High Queen of Prythian. Amarantha tricked the seven High Lords out of their power and took control of Prythian within days and proclaimed herself High Queen of Prythian. She then set up her court in Under the Mountain, a sacred place for Prythian. She took Rhysand, now High Lord of the Night Court, as her sex slave as a punishment for his father's actions, Rhysand complied but secretly hated her. Ever since she became High Queen, Amarantha attempted to win over Tamlin for the past hundred years. Amarantha remains unopposed to this day.
