A "Magic System" refers to the set of rules and principles that govern how magic works within a fictional universe. It defines the sources of magical power, the limitations of its use, and the consequences of its application. Magic systems can vary widely, from simple spells to complex rituals, and can be influenced by factors such as cultural beliefs, natural elements, or magical creatures. In literature and games, a well-defined magic system enhances world-building and character development. It allows for consistent storytelling and can create tension and conflict. Examples of magic systems include hard magic, which has strict rules, and soft magic, which is more mysterious and undefined, often used to create wonder and intrigue.
