Veng the Manipulator is one of the most hideous enemies to mankind the world has ever known. His unique combination of Psionic abilities and magic items allow him to sneak into his victims dreams, and modify and direct the dreams, as well as “adjust memories”. Over the years, he has ‘programmed’ an insidious network of totally devoted followers. Using his natural ability of ‘Wisdom Drain’, he has created an army of willing slaves.
Magic should have side effects, both expected and unexpected - fortuitous and deplorable. Expected side effects add anticipation, while unexpected ones increase the drama of the scene. The result can be comedic or dire, it dpends on which circumstances work best for your game.
