Shades of Amber
…What can I say of Thessia, I never liked her, she was quite a bitch while we were younger always spoiling whatever small intrigues we attempted. She despised the petty cruelties that are so common among the courts, which is not to say she was not capable of them. She never really recovered from her sister’s death, and for years she was one Mandor and Dara’s fiercest fiercest opponents. But then, she was always one for lost causes…
The diaries of Lady Slaughna
