To most, thoughts of yordles do not conjure images to be feared. The easygoing half-pint race, though fierce, is often regarded with some degree of joviality. Their high-pitched voices and naturally cute forms inspire something of a protective instinct in the larger races, or at least bring to mind images of children playing at being adults. Every now and again, however, a yordle turns so bad that even at its small stature it strikes terror into the hearts of others. Veigar is one such twisted yordle. As a master of the magical black arts, as well as a corrupter of cosmic energy, he is one of the most powerful sorcerers on Valoran.
