Politea Brumae is a graduate of Alfea, and was Daphne’s best friend and roommate. She’s also from Domino (specifically the Kingdom of Aletene), which helped the girls bond faster, and they became close really fast. She’s the Fairy of Poisonous Fish, being able to control, generate and accentuate different types of poisonous fluids, spores and such related to animals. Her Source is Poison, with added Water and Fauna. She did the Sirenix Quest alongside Daphne after their last year at Alfea, and managed to get a record time in beating it as mere Enchantix faires - the usual time limit for Enchantix fairies is 10 weeks, they did it in 3 days. She’s also an elf.
While she did genuinely like Daphne (and more than as a friend I might add), she’s inmensely jealous of how, thanks to her Dragon Aura, she can do more complicated magic far more easily, as well as a low dislike for Daphne’s privileged status as a Princess. Said bitterness grew over time, and she found herself both loathing and loving her best friend, almost to a point of obsession. She realized this was toxic behavior and distanced herself for a while, but the feelings increased, and she started missing her terribly. The day before she tried to visit Daphne, she was approached by Myraria herself, who offered her a chance to be even stronger than Daphne if she would help her enter the castle. Politea’s will shattered and she gleefully accepted. Once inside the castle, she freed Myraria (who had hid inside her hand mirror) and was promptly turned into stone by the Witch, as “thanks”, claiming this was better than outright killing her. She was sent to Infimare rather than Obsidia, however, and spent there the next 18 years until Bloom and Daphne broke the Curse of Domino. She blamed Daphne and “Nina” (Bloom’s baby name) for her situation, even if she knew her decision was hers alone, and ended up traveling through Infimare without a path, planning a “revenge” for a couple years until a golden chance arose.
