Abasdarhon's Castle

/ You forgot about the episode where the structuralist is impressed by a conversation with a necromancer and starts to question herself, wondering if she's living her life correctly, and if the voice in her head is misleading her? At first, she just doubts, then it scares her, and Maylin eventually almost decides to be good. But then something bad happens to her; some scoundrel tries to drug/poison/take advantage of/kill her, all at once. Cassmetra immediately says, "I told you so!" And that's it; Maylin becomes the final evil boss. /
