Magical Wavelength Frequency or MWF is the flow of magic the user maintains. The higher frequency someones magic wavelength is the better their potential for using spells are. Most mages have an average MWF. Alchemists usually have a really low MWF and have trouble casting even basic spells. Anyone can channel their MWF frequency into other things, like ID locks on their homes to unlock their doors or into personal transportation vehicles like skyboards to get them to work.
