Magic Systems Quick Reference for Fantasy Writers

The fundamental origin or fuel that enables magical effects in your world

Example: Brandon Sanderson's Stormlight Archive uses stormlight captured in gemstones; Terry Pratchett's Discworld treats magic as a natural force like gravity

How individuals tap into, channel, or manipulate magical power

Example: Rothfuss's Name of the Wind requires understanding true names; Le Guin's Earthsea uses spoken words in the Old Speech; genetic inheritance in Harry Potter

The physical, mental, or ritual actions required to produce magical effects

Example: Precise wand movements and incantations (Harry Potter), mental visualization and willpower (Wheel of Time), or runic inscriptions (Elder Scrolls)

Physical, mental, or spiritual toll that magic takes on the user

Example: Physical exhaustion in Mistborn, aging in Howl's Moving Castle, or sanity loss when touching the True Source's tainted half in Wheel of Time

Limited availability of magical fuel, components, or catalysts

Example: Rare spell components in D&D, finite mana pools, depleting stormlight in gemstones, or the gradual weakening of magic in Tolkien's Middle-earth

Training, talent, or knowledge barriers that prevent universal access to magic

Example: Years of study at Hogwarts, innate Allomantic genetics in Mistborn, or the rare ability to hear the Music of Creation in Middle-earth

Specific areas or types of effects that magic can and cannot influence

Example: Sanderson's Allomancy only affects metals; Earthsea magic cannot create food; Harry Potter's magic cannot resurrect the dead or create true love

How magic shapes culture, economy, governance, and daily life in your world

Example: Magic-powered industry in Eberron, wizard aristocracy in Dresden Files, or the careful balance of power between Aes Sedai and nations in Wheel of Time

How the existence of magic has shaped species, cultures, and civilizations over time

Example: Anti-magic materials like iron affecting fae, societies built around controlling mages, or the development of magic-resistant architecture and warfare

The fundamental principles that govern how magic behaves, even if characters don't fully understand them

Example: Conservation of energy in Fullmetal Alchemist's alchemy, Sanderson's Laws of Magic, or the balance between Order and Chaos in Moorcock's Eternal Champion

What characters and cultures don't know about magic, creating room for discovery and plot development

Example: Lost magical arts, forbidden knowledge, evolving understanding of magic's true nature, or rediscovering ancient techniques

What happens when magic goes wrong, is misused, or encounters interference

Example: Wheel of Time's taint causing madness, spell failure in D&D, or magical accidents creating permanent consequences like lycanthropy
