The idea of
hard magic and soft magic was popularized by [Brandon] Sanderson for world building and creating magic systems in fictional settings.
[38][39][40] The terminology of hard and soft originate from
hard and soft sciences,
hard science fiction,
hard fantasy and
soft science fiction and both terms are approximate ways of characterizing two ends of a spectrum.
[41][42] Hard magic systems follow specific rules, the magic is controlled and explained to the reader in the narrative detailing the mechanics behind the way the magic 'works', and can be used for building interesting worlds that revolve around the magic system.
[43][44] Soft magic systems may not have clearly defined rules or limitations, or provide limited exposition regarding their workings, and are used to create a sense of wonder to the reader.
[38][45][46]
Sanderson's three laws of magic are creative writing guidelines that can be used to create magic systems for fantasy stories.
- An author's ability to solve conflict with magic is directly proportional to how well the reader understands said magic.[41]
- Weaknesses, limits and costs are more interesting than powers.[47]
- The author should expand on what is already a part of the magic system before something entirely new is added, as this may otherwise entirely change how the magic systems fits into the fictional world.[48]
