"They're evil, those two."
Idith Branko (b.1993) was introduced in Charlie Bone and the Castle of Mirrors. She is one of the bad endowed children, and is descended from one of the Red King's bad children, Olga. She is a telekinetic, like her twin sister, Inez Branko. She is also distantly related to Zelda Dobinsky, who is also a telekinetic. Idith and her sister hardly ever talk, and are impossible to tell apart. They don't always get along with each other. Idith's family owns a shop called "Fine and Fancy" which was renamed "Not the Pets' Cafe" in the eighth book. Her mother Natalia Branko (Maiden name Natalia Dobinski) is also telekinetic, and she can produce anything she wants out of thin air, and her father is normal.
Inez and Idith both have "...shiny black hair, cut just below the ears, long bangs, and complexions that were so pale and smooth, they looked like porcelain." The twins only smile when somebody is in trouble. Idith also has sharp blue eyes, and a piercing gaze like her twin sister Inez. The twins are said to have china dark blue eyes in the fourth book, and black eyes in the fifth, so the colour could be in between.
Like her distant relative Zelda, and her twin Inez, Idith is telekinetic. Her powers, along with her sisters, can lift ladders, topple chimnies and lampposts, and other amazing but terrifying things.
