Magic can be used by the humans and magical creatures of the Endless Woods but some humans choose not to focus on sorcery. Magic can alter the fabric of reality and defy the natural laws, cast enchantments and curses, mogrify into animals and plants, manipulate the elements, summon storms and create illusions. The morality of magic relies on the user and can be used for Good or Evil.
There is no one way to use magic but to summon and use it, someone must summon enough emotion and purpose to use magic. While emotion and will, someone can use magic. Mogrifying into animals seems to require only sheer force of will. However, other forms of magic require more than just thought and emotion to acquire the desired effects. Spells, a set of words spoken in a certain manner can focus magic and better change the world around the user. Mogrification into plants like tulips and ferns seems to require a spell.
