In Alexander Melentyevich Volkov's Magic Land series, the Witch's name is Villina. When the Wicked Witch of the East tried (in that continuity) to exterminate the humanity by means of a magical hurricane, Villina changed the spell so that it only affected one house (which, as her magical book said, was always empty during storms), and dropped it upon the Wicked Witch. Her magical slate is changed into a tiny book which transforms into a giant tome when blown upon, and, in addition to the divination qualities, also functions as an encyclopedia. She appears in two books after the first one (although in one of them she appears off stage, and it is narrated to the main characters).
