Plachta

Plachta is a character in Atelier Sophie: The Alchemist of the Mysterious Book, Atelier Firis: The Alchemist and the Mysterious Journey and Atelier Lydie & Suelle: The Alchemists and the Mysterious Paintings. Originally an alchemist that was turned into a book 500 years ago, one day Sophie discovers her and then she becomes Sophie's alchemy teacher. Plachta is a talking book who has lost her memories. As Sophie comes up with new recipes and adds them to the book, she recovers new memories. It is eventually revealed that 500 years ago, Plachta was once a human alchemist. With the help of Sophie and her friends, her soul is moved to a doll body, allowing Plachta to live a human-like life again. Plachta and Luard were once close friends, but she eventually had to fight him when Luard got obsessed with a harmful kind of alchemy. Plachta ruptured Luard's soul into the artificial lifeforms known as Atomina and Meklet. However, fearing that Luard would regain his ability to use alchemy through the Cauldron of Alchemical Brilliance, she sealed her soul inside a book. Plachta is also the creator of the cauldron.
