A young witch from the Chalk, a farming region on the Disc, who begins her training as a witch at nine years old and gradually grows into one of the most capable witches on the Disc. Tiffany's story across five novels is Pratchett's exploration of growing up, responsibility, and what it means to be the person who stands between the community and the things that threaten it. She is aided by the Nac Mac Feegle (tiny, blue, extremely violent fairy folk) and eventually becomes the witch of the Chalk.
