Usually it is a power that normal people don't have, and is wielded instead by a special caste (wizards, sorcerers, witches, mages, etc.)
While this is true for many examples, a significant number of magic questions describe the popular, widespread use of magic in society.
This line may accurately describe some magic questions, but it doesn't contribute much - the rest of the wiki pretty much says it all -
Magic or sorcery is an attempt to understand and exploit supernatural forces, using rituals, symbols, actions, gestures and language...
and it may alienate other questions.
Is there a good reason to keep this line of the wiki?
