'I'm the irresistible Adrienne.' -Adrienne, Series I, Chapter 23

Bio: The eldest Tonnerre Sister and Bounty Huntress extraordinaire, Adrienne was a big-haired and big-chested material girl. Born into the Cielnoir clan, she and her younger sister, Alicia, would take any job that needed doing, no matter how heinous, just as long as it paid. Their missions ranged from simple kidnappings to murders, and they were both involved in the revival of Malaphaera. Adrienne and Alicia came from ten years in the future to kidnap Ana when she came to the past (our heroes' present day). Adrienne was a lively character, often on the obnoxious side, with a libido as large as her bra size. Adrienne had a liking for anything pretty and fluffy, and therefore had a large collection of jewellery, clothes and stuffed animals. We found out that Adrienne's first love was Allen Foehn, a Felaxian musician, but this relationship was very one-sided. Allen soon broke up with her.

When she first met Thorn, she instantly fell for him (whether he falls into the 'cute' or 'fluffy' category is not really known), and they had a brief relationship resulting in Lahrne. She seemed to love calling Thorn sickly sweet and often food-related pet names. Adrienne met her end in a fight between Thorn and Tobias, in which Tobias' Demon, Venah, went after Adrienne rather than Thorn. Thorn managed to rescue Lahrne from an alternate future, as he was not born during the time period in which Adrienne was killed. Her essence now resides in the skies of Dalimoor, occasionally causing storms. Lahrne was very attached to his mother and tried to unsuccessfully ressurect her by taking the power of the Cywyrms in the forest, Kitzie's kittens and Thorn.
