Veruca and Morrigan (Jewels In The Sky)

They were Veruca and Morrigan, the two collaborators of the Auberinian people. Their parents had helped with the Onitarian Holocaust as overseers. Before their execution, Veruca and Morrigan had vowed to finish what their parents had started, even it meant betraying and killing their own people. Of course Veruca dies in the fourth story and Morrigan (who disguises herself as Dylan in the 13th story) keeps being loyal to the evil Empress.
